[ Upstream commit 7f0d078667a494466991aa7133f49594f32ff6a2 ]
Commit 747834ab8347 ("ARM: OMAP2+: hwmod: revise hardreset behavior") made
the call to _enable() conditional based on no oh->rst_lines_cnt. This
caused the return value to be potentially uninitialized. Curiously we see
no compiler warnings for this, probably as this gets inlined.
We call _setup_reset() from _setup() and only _setup_postsetup() if the
return value is zero. Currently the return value can be uninitialized for
cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

With a wl1251 child node of mmc3 in the device tree decoded
in omap_hsmmc.c to handle special wl1251 initialization, we do
no longer need to instantiate the mmc3 through pdata quirks.
We also can remove the wlan regulator and reset/interrupt definitions
and do them through device tree.

[ Upstream commit 8ad8041b98c665b6147e607b749586d6e20ba73a ]
For ti,sysc-omap4 compatible devices with no sysstatus register, we do have
reset done status available in the SOFTRESET bit that clears when the reset
is done. This is documented for example in am437x TRM for DMTIMER_TIOCP_CFG
register. The am335x TRM just says that SOFTRESET bit value 1 means reset is
ongoing, but it behaves the same way clearing after reset is done.
With the ti-sysc driver handling this automatically based on no sysstatus
register defined, we see warnings if SYSC_HAS_RESET_STATUS is missing in the
legacy platform data:
ti-sysc 48042000.target-module: sysc_flags 00000222 != 00000022
ti-sysc 48044000.target-module: sysc_flags 00000222 != 00000022
ti-sysc 48046000.target-module: sysc_flags 00000222 != 00000022
...
Let's fix these warnings by adding SYSC_HAS_RESET_STATUS. Let's also
remove the useless parentheses while at it.
If it turns out we do have ti,sysc-omap4 compatible devices without a
working SOFTRESET bit we can set up additional quirk handling for it.

[ Upstream commit 45da5e09dd32fa98c32eaafe2513db6bd75e2f4f ]
We have errata i688 workaround produce warnings on SoCs other than
omap4 and omap5:
omap4_sram_init:Unable to allocate sram needed to handle errata I688
omap4_sram_init:Unable to get sram pool needed to handle errata I688
This is happening because there is no ti,omap4-mpu node, or no SRAM
to configure for the other SoCs, so let's remove the warning based
on the SoC revision checks.
As nobody has complained it seems that the other SoC variants do not
need this workaround.

omap3xxx_prm_enable_io_wakeup() is marked __init, but its caller is not, so
we get a warning with clang-8:
WARNING: vmlinux.o(.text+0x343c8): Section mismatch in reference from the function omap3xxx_prm_late_init() to the function .init.text:omap3xxx_prm_enable_io_wakeup()
The function omap3xxx_prm_late_init() references
the function __init omap3xxx_prm_enable_io_wakeup().
This is often because omap3xxx_prm_late_init lacks a __init
annotation or the annotation of omap3xxx_prm_enable_io_wakeup is wrong.
When building with gcc, omap3xxx_prm_enable_io_wakeup() is always
inlined, so we never noticed in the past.

[ Upstream commit 5388a5b82199facacd3d7ac0d05aca6e8f902fed ]
machine_crash_nonpanic_core() does this:
while (1)
cpu_relax();
because the kernel has crashed, and we have no known safe way to deal
with the CPU. So, we place the CPU into an infinite loop which we
expect it to never exit - at least not until the system as a whole is
reset by some method.
In the absence of erratum 754327, this code assembles to:
b .
In other words, an infinite loop. When erratum 754327 is enabled,
this becomes:
1: dmb
b 1b
It has been observed that on some systems (eg, OMAP4) where, if a
crash is triggered, the system tries to kexec into the panic kernel,
but fails after taking the secondary CPU down - placing it into one
of these loops. This causes the system to livelock, and the most
noticable effect is the system stops after issuing:
Loading crashdump kernel...
to the system console.
The tested as working solution I came up with was to add wfe() to
these infinite loops thusly:
while (1) {
cpu_relax();
wfe();
}
which, without 754327 builds to:
1: wfe
b 1b
or with 754327 is enabled:
1: dmb
wfe
b 1b
Adding "wfe" does two things depending on the environment we're running
under:
- where we're running on bare metal, and the processor implements
"wfe", it stops us spinning endlessly in a loop where we're never
going to do any useful work.
- if we're running in a VM, it allows the CPU to be given back to the
hypervisor and rescheduled for other purposes (maybe a different VM)
rather than wasting CPU cycles inside a crashed VM.
However, in light of erratum 794072, Will Deacon wanted to see 10 nops
as well - which is reasonable to cover the case where we have erratum
754327 enabled _and_ we have a processor that doesn't implement the
wfe hint.
So, we now end up with:
1: wfe
b 1b
when erratum 754327 is disabled, or:
1: dmb
nop
nop
nop
nop
nop
nop
nop
nop
nop
nop
wfe
b 1b
when erratum 754327 is enabled. We also get the dmb + 10 nop
sequence elsewhere in the kernel, in terminating loops.
This is reasonable - it means we get the workaround for erratum
794072 when erratum 754327 is enabled, but still relinquish the dead
processor - either by placing it in a lower power mode when wfe is
implemented as such or by returning it to the hypervisior, or in the
case where wfe is a no-op, we use the workaround specified in erratum
794072 to avoid the problem.
These as two entirely orthogonal problems - the 10 nops addresses
erratum 794072, and the wfe is an optimisation that makes the system
more efficient when crashed either in terms of power consumption or
by allowing the host/other VMs to make use of the CPU.
I don't see any reason not to use kexec() inside a VM - it has the
potential to provide automated recovery from a failure of the VMs
kernel with the opportunity for saving a crashdump of the failure.
A panic() with a reboot timeout won't do that, and reading the
libvirt documentation, setting on_reboot to "preserve" won't either
(the documentation states "The preserve action for an on_reboot event
is treated as a destroy".) Surely it has to be a good thing to
avoiding having CPUs spinning inside a VM that is doing no useful
work.

[ Upstream commit 6d609b35c815ba20132b7b64bcca04516bb17c56 ]
When the RTC lock and unlock functions were introduced it was likely
assumed that they would always be called from irq enabled context, hence
the use of local_irq_disable/enable. This is no longer true as the
RTC+DDR path makes a late call during the suspend path after irqs
have been disabled to enable the RTC hwmod which calls both unlock and
lock, leading to IRQs being reenabled through the local_irq_enable call
in omap_hwmod_rtc_lock call.
To avoid this change the local_irq_disable/enable to
local_irq_save/restore to ensure that from whatever context this is
called the proper IRQ configuration is maintained.

Call secure services to enable ACTLR[0] (Enable invalidates of BTB with
ICIALLU) when branch hardening is enabled for kernel.
On GP devices OMAP5/DRA7, there is no possibility to update secure
side since "secure world" is ROM and there are no override mechanisms
possible. On HS devices, appropriate PPA should do the workarounds as
well.
However, the configuration is only done for secondary core, since it is
expected that firmware/bootloader will have enabled the required
configuration for the primary boot core (note: bootloaders typically
will NOT enable secondary processors, since it has no need to do so).

[ Upstream commit d3be6d2a08bd26580562d9714d3d97ea9ba22c73 ]
For platform_suspend_ops, the finish call is too late to re-enable wake
irqs and we need re-enable wake irqs on wake call instead.
Otherwise noirq resume for devices has already happened. And then
dev_pm_disarm_wake_irq() has already disabled the dedicated wake irqs
when the interrupt triggers and the wake irq is never handled.
For devices that are already in PM runtime suspended state when we
enter suspend this means that a possible wake irq will never trigger.
And this can lead into a situation where a device has a pending padconf
wake irq, and the device will stay unresponsive to any further wake
irqs.
This issue can be easily reproduced by setting serial console log level
to zero, letting the serial console idle, and suspend the system from
an ssh terminal. Then try to wake up the system by typing to the serial
console.
Note that this affects only omap3 PRM interrupt as that's currently
the only omap variant that does anything in omap_pm_wake().
In general, for the wake irqs to work, the interrupt must have either
IRQF_NO_SUSPEND or IRQF_EARLY_RESUME set for it to trigger before
dev_pm_disarm_wake_irq() disables the wake irqs.

[ Upstream commit db35340c536f1af0108ec9a0b2126a05d358d14a ]
When more than one GP timers are used as kernel system timers and the
corresponding nodes in device-tree are marked with the same "disabled"
property, then the "attr" field of the property will be initialized
more than once as the property being added to sys file system via
__of_add_property_sysfs().
In __of_add_property_sysfs(), the "name" field of pp->attr.attr is set
directly to the return value of safe_name(), without taking care of
whether it's already a valid pointer to a memory block. If it is, its
old value will always be overwritten by the new one and the memory block
allocated before will a "ghost", then a kmemleak happened.
That the same "disabled" property being added to different nodes of device
tree would cause that kind of kmemleak overhead, at least once.
To fix it, allocate the property dynamically, and delete static one.

[ Upstream commit d09220a887f70368afa79e850c95e74890c0a32d ]
With the CMA changes from Joonsoo Kim <iamjoonsoo.kim@lge.com>, it
was noticed that n900 stopped booting. After investigating it turned
out that n900 save_secure_ram_context does some whacky virtual to
physical address translation for the SRAM data address.
As we now only have minimal parts of omap3 idle code copied to SRAM,
running save_secure_ram_context() in SRAM is not needed. It only gets
called on PM init. And it seems there's no need to ever call this from
SRAM idle code.
So let's just keep save_secure_ram_context() in DDR, and pass it the
physical address of the parameters. We can do everything else in
omap-secure.c like we already do for other secure code.
And since we don't have any documentation, I still have no clue what
the values for 0, 1 and 1 for the parameters might be. If somebody has
figured it out, please do send a patch to add some comments.

of_find_node_by_name() drops the reference to the passed device node.
The commit referenced above exposes this problem.
To fix the problem, use of_get_child_by_name() instead of
of_find_node_by_name(); of_get_child_by_name() does not drop
the reference count of passed device nodes. While semantically
different, we only look for immediate children of the passed
device node, so of_get_child_by_name() is a more appropriate
function to use anyway.
Release the reference to the device node obtained with
of_get_child_by_name() after it is no longer needed to avoid
another device node leak.
While at it, clean up the code and change the return type of
omap3xxx_hwmod_is_hs_ip_block_usable() to bool to match its use
and the return type of of_device_is_available().

commit 04abaf07f6d5cdf22b7a478a86e706dfeeeef960 upstream.
Starting from commit 5de85b9d57ab ("PM / runtime: Re-init runtime PM
states at probe error and driver unbind") pm_runtime core now changes
device runtime_status back to after RPM_SUSPENDED after a probe defer.
Certain OMAP devices make use of "ti,no-idle-on-init" flag which causes
omap_device_enable to be called during the BUS_NOTIFY_ADD_DEVICE event
during probe, along with pm_runtime_set_active.
This call to pm_runtime_set_active typically will prevent a call to
pm_runtime_get in a driver probe function from re-enabling the
omap_device. However, in the case of a probe defer that happens before
the driver probe function is able to run, such as a missing pinctrl
states defer, pm_runtime_reinit will set the device as RPM_SUSPENDED and
then once driver probe is actually able to run, pm_runtime_get will see
the device as suspended and call through to the omap_device layer,
attempting to enable the already enabled omap_device and causing errors
like this:
omap-gpmc 50000000.gpmc: omap_device: omap_device_enable() called from
invalid state 1
omap-gpmc 50000000.gpmc: use pm_runtime_put_sync_suspend() in driver?
We can avoid this error by making sure the pm_runtime status of a device
matches the omap_device state before a probe attempt. By extending the
omap_device bus notifier to act on the BUS_NOTIFY_BIND_DRIVER event we
can check if a device is enabled in omap_device but with a pm_runtime
status of RPM_SUSPENDED and once again mark the device as RPM_ACTIVE to
avoid a second incorrect call to omap_device_enable.

error and driver unbind")

commit f86a2c875fd146d9b82c8fdd86d31084507bcf4c upstream.
The commit 55ee7017ee31 ("arm: omap2: board-generic: use
omap4_local_timer_init for AM437x") unintentionally changes the
clocksource devices for AM437x from OMAP GP Timer to SyncTimer32K.
Unfortunately, the SyncTimer32K is starving from frequency deviation
as mentioned in commit 5b5c01359152 ("ARM: OMAP2+: AM43x: Use gptimer
as clocksource") and, as reported by Franklin [1], even its monotonic
nature is under question (most probably there is a HW issue, but it's
still under investigation).
Taking into account above facts It's reasonable to rollback to the use
of omap3_gptimer_timer_init().

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Arnd Bergmann:
"The cleanups for v4.9 are a little larger that usual, but thankfully
that is almost exclusively due to removing a significant number of
files that have become obsolete after the still ongoing conversion of
old board files to devicetree.
- for mach-omap2, which is still the largest platform in arch/arm/,
the conversion to DT is finally complete after the Nokia N900 is
now fully supported there, along with the omap3 LDP, and we can
remove those two board files. If no regressions are found, another
large cleanup for the platform will happen as a follow-up, removing
dead code and restructuring the platform based on being DT-only.
- In mach-imx, similar work is ongoing, but has not come that far.
This time, we remove the obsolete board file for the i.MX1
generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now
DT-only. The remaining board files are for i.MX2 and i.MX3 machines
based on old ARM926 or ARM1136 cores that should work with DT in
principle.
- realview has just been converted from board files to DT, and a lot
of code gets removed in the process. This is the last
ARM/Keil/Versatile derived platform that was still using board
files, the other ones being integrator, versatile and vexpress. We
can probably merge the remaining code into a single directory in
the near future.
- clps711x had completed the conversion in v4.8, but we accidentally
left the files in place that should have been deleted then"

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.9 series:
Subsystem improvements:
- do away with the last users of the obsolete Kconfig options
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
always sounded like an item on a wishlist to Santa Claus to me). We
can now select GPIOLIB and be done with it, for all archs. After
some struggle it even work on UM. Not that it has GPIO, but if it
wants to, it can select the library.
- continued efforts to make drivers properly either tristate or bool.
- introduce a warning for drivers assigning default triggers to their
irqchip lines when probed from device tree, so we find and fix
these ambigous drivers. It is agreed that in the OF config path,
the device tree defines trigger characteristics.
- the same warning, mutatis mutandis, for ACPI-probed GPIO irqchips.
- we introduce the ability to mark certain IRQ lines as "unusable" as
they can be taken by BIOS/firmware, unrouted in silicon and
generally nasty if you use them, and such things. This is put to
good use in the STMPE driver and also in the Cherryview pin control
driver.
- a new "mockup" virtual GPIO device that can be used for testing.
The plan is to add unit tests under tools/* for exercising this
device and verify that the kernel code paths are working as they
should.
- make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
implicit all the time, but when people started building UM with
allyesconfig or allmodconfig it exploded in their face.
- move some stray bits of device tree and ACPI HW description
callbacks down into their respective implementation silo. These
were causing issues when compiling on !HAS_IOMEM as well, so now
eventually UM compiles the GPIOLIB library if it wants to.
New drivers:
- new driver for the Aspeed GPIO front-end companion to the pin
controller merged through the pin control tree.
- new driver for the LP873x PMIC GPIO portions.
- new driver for Technologic Systems' I2C FPGA GPIO such as TS4900,
TS-7970, TS-7990 and TS-4100.
- new driver for the Broadcom BCM63xx series including BCM6338 and
BCM6345.
- new driver for the Intel WhiskeyCove PMIC GPIO.
- new driver for the Allwinner AXP209 PMIC GPIO portions.
- new driver for Diamond Systems 48 line GPIO-MM, another of these
port-mapped I/O expansion cards.
- support the STMicroelectronics STMPE1600 variant in the STMPE
driver.
Driver improvements:
- the STMPE driver now supports rising/falling edge detection
properly for IRQs.
- the PCA954x will now fetch and enable its VCC regulator properly.
- major rework of the PCA953x driver with the goal of eventually
switching it over to use regmap and thus modernize it even more.
- switch the IOP driver to use the generic MMIO GPIO library.
- move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
over to this subsystem from MFD, achieveing some separation of
concerns"

Merge "drop last omap3 board files for v4.8" from Tony Lindgren:
Remove the last two legacy board-*.c files for omap3 for legacy
booting for v4.8 to allow making mach-omap2 device tree only for
v4.9.
We've had Nokia N900 and omap3 LDP board-*.c files remaining
while other omap3 devices have been device tree only for quite
a while now. Also N900 and LDP have had device tree based booting
working for years now, but few drivers for N900 were still only
working in legacy only mode until recently. With the remaining
issues out of the way, we discussed on the mailing lists that
we're finally OK to remove the remaining board-*.c files.
For the timing of this pull request, I wanted to wait until
v4.8-rc1 is out to make sure the legacy booting still works fine
after the merge window before doing it.
And for v4.8, let's not touch any other platform data in case we
still need to revert for some reason. This makes the revert just a
question of adding back the legacy board-*.c files.
Then if no issues, we can remove the unused remaining platform
data later on for v4.9.

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.
Using the macro makes the code more readable by helping abstract away some
