2018-03-24ARM: DRA7: clockdomain: Change the CLKTRCTRL of CM_PCIE_CLKSTCTRL to SW_WKUPKishon Vijay Abraham I
[ Upstream commit 2c949ce38f4e81d7487f165fa3b8f77d74a2a6c4 ] The PCIe programming sequence in TRM suggests CLKSTCTRL of PCIe should be set to SW_WKUP. There are no issues when CLKSTCTRL is set to HW_AUTO in RC mode. However in EP mode, the host system is not able to access the MEMSPACE and setting the CLKSTCTRL to SW_WKUP fixes it.

2018-03-18ARM: omap2: hide omap3_save_secure_ram on non-OMAP3 buildsArnd Bergmann
commit 863204cfdae98626a92535ac928ad79f4d6b74ff upstream. In configurations without CONFIG_OMAP3 but with secure RAM support, we now run into a link failure: arch/arm/mach-omap2/omap-secure.o: In function `omap3_save_secure_ram': omap-secure.c:(.text+0x130): undefined reference to `save_secure_ram_context' The omap3_save_secure_ram() function is only called from the OMAP34xx power management code, so we can simply hide that function in the appropriate #ifdef.

2018-02-25ARM: AM33xx: PRM: Remove am33xx_pwrdm_read_prev_pwrst functionKeerthy
[ Upstream commit b6d6af7226465b6d11eac09d0be2ab78a4a9eb62 ] Referring TRM Am335X series: http://www.ti.com/lit/ug/spruh73p/spruh73p.pdf The LastPowerStateEntered bitfield is present only for PM_CEFUSE domain. This is not present in any of the other power domains. Hence remove the generic am33xx_pwrdm_read_prev_pwrst hook which wrongly reads the reserved bit fields for all the other power domains. Reading the reserved bits leads to wrongly interpreting the low power transitions for various power domains that do not have the LastPowerStateEntered field. The pm debug counters values are wrong currently as we are incrementing them based on the reserved bits.

2018-02-25ARM: OMAP2+: Fix SRAM virt to phys translation for save_secure_ram_contextTony Lindgren
[ 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.

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().

2017-07-05ARM: OMAP2+: omap_device: Sync omap_device and pm_runtime after probe deferDave Gerlach
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.

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().

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.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup 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. * tag 'omap-for-v4.8/legacy-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Drop legacy board file for LDP ARM: OMAP2+: Drop legacy board file for n900

Previously the low-level CM call internal to the _omap4_wait_target_ready/disable calls was responsible for checking for a valid clkctrl_offs. Now we must also consider the value of the prcm.omap4.flags because if HWMOD_OMAP4_ZERO_CLKCTRL_OFFSET is set in the flags then clkctrl_offs of 0 is valid. Let's add this check into the _omap4_wait_target_ready/disable where we have access to both the clkctrl_offs and the flags values and simply return 0 without calling the low level CM call at all, which would have returned 0 anyway if the clktrl_offs was zero.

2016-07-10ARM: OMAP2+: Drop legacy board file for LDPTony Lindgren
Let's drop the last two remaining omap3 legacy boot board files. Let's only use the device tree based booting known to work for these two boards. We still have two omap3 boards booting in legacy mode in addition to device tree based booting. All the other ten or so omap2+ SoCs have been booting using device tree mode only for years now. This has allowed us to get rid of quite a bit of arch/arm/mach-omap2 related platform init code in favor of dts and driver changes. Pretty much the only remaining known users for omap3 legacy boot board files are Kevin's and Russell's boot test systems, and N900 kernel tree maintained by Pali and Ivaylo. And all of them are also supporting the device tree based booting. The legacy booting mode has been kept around mostly to verify against regressions. As there is still a slim chance of possible other uses of the mainline kernel for these boards, let's just drop the board files for v4.8, and let's not touch the related platform init code until around v4.9 time if no issues are found. This makes it trivial for us to add back the board files with a simple revert. Signed-off-by: Tony Lindgren <tony@atomide.com>

* commit '5c34a4e89c743339f78cafb2f2a826a010f0746a': ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB ARM: uniphier: drop code for old DT binding These cause a harmless conflict with the clps711x multiplatform support, and it's easy to resolve. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2016-07-04ARM: AM33xx: fix module_wait_ready without clkctrl registerTero Kristo
If the module has no clkctrl register defined, module_wait_ready should not try to access this. This can potentially cause an illegal register access, and result in bad idle reporting also. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2016-07-04ARM: OMAP2+: clockdomain: add usecounting support to autoidle APIsTero Kristo
The previous implementation was racy in many locations, where the current status of the clockdomain was read out, some operations were executed, and the previous status info was used afterwards to decide next state for the clockdomain. Instead, fix the implementation of the allow_idle / deny_idle APIs to properly have usecounting support. This allows clean handling internally within the clockdomain core, and simplifies the usage also within hwmod.

2016-07-04ARM: OMAP2+: timer: change order of hwmod data handlingTero Kristo
With the introduction of hwmod module clocks, the name of the hwmod main clk may not be available before hwmod setup, as hwmod setup may lookup the main clock dynamically based on the hwmod name. Thus, change the order of hwmod setup and main clock handling for the timer code, to make sure the main clock is going to be available.

2016-07-04ARM: OMAP2+: hwmod: fetch main_clk based on hwmod nameTero Kristo
With the transition to hwmod module clocks, all hwmods will have their main clocks named <hwmod_name>_mod_ck. Use this info to fetch main_clk, and use it if found. Also, if a main_clk is found based on the hwmod name, disable the direct PRCM modulemode access from hwmod. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
