Fix PCIe clock and reset not conforming to specification by moving PCIe
reset handling including the PLX PEX 8605 errata 5 workaround from the
board platform data into the right places timing wise in the PCIe driver
itself.
Also add a kernel command line argument to allow using the Apalis GPIO7
as a regular GPIO rather than for above mentioned PLX PEX 8605
workaround:
pex_perst=0

Floating pins towards the camera input level-shifter cause it to
consume at least 100mW of power even in idle. This patch fixes this by
configuring pull-downs on all multiplexed camera input pins.

This commit adds support for Epson S2D13P04 (4-input
analog video decoder with parallel interface) for
Colibri T30.
Currently the only supported standard is PAL-B/G/I/N
and the output is arranged in 'merge mode' (4 input
streams on one screen)

While working on the 32-bit ARM port of UEFI, I noticed a strange
corruption in the kernel log. The following snprintf() statement
(in drivers/firmware/efi/efi.c:efi_md_typeattr_format())
snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]",
was producing the following output in the log:
| | | | | |WB|WT|WC|UC]
| | | | | |WB|WT|WC|UC]
| | | | | |WB|WT|WC|UC]
|RUN| | | | |WB|WT|WC|UC]*
|RUN| | | | |WB|WT|WC|UC]*
| | | | | |WB|WT|WC|UC]
|RUN| | | | |WB|WT|WC|UC]*
| | | | | |WB|WT|WC|UC]
|RUN| | | | | | | |UC]
|RUN| | | | | | | |UC]
As it turns out, this is caused by incorrect code being emitted for
the string() function in lib/vsprintf.c. The following code
if (!(spec.flags & LEFT)) {
while (len < spec.field_width--) {
if (buf < end)
*buf = ' ';
++buf;
}
}
for (i = 0; i < len; ++i) {
if (buf < end)
*buf = *s;
++buf; ++s;
}
while (len < spec.field_width--) {
if (buf < end)
*buf = ' ';
++buf;
}
when called with len == 0, triggers an issue in the GCC SRA optimization
pass (Scalar Replacement of Aggregates), which handles promotion of signed
struct members incorrectly. This is a known but as yet unresolved issue.
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular
case, it is causing the second while loop to be executed erroneously a
single time, causing the additional space characters to be printed.
So disable the optimization by passing -fno-ipa-sra.

With compilers which follow the C99 standard (like modern versions of gcc and
clang), "extern inline" does the wrong thing (emits code for an externally
linkable version of the inline function). In this case using static inline
and removing the NULL version of return_address in return_address.c does
the right thing.

The Ixora carrier board has a few MXM3 pins repurposed as follows:
Functionality MXM3 Pin
LED4_RED 146
LED4_GREEN 162
LED5_RED 156
LED5_GREEN 152
PCIE1_WDISABLE_N 144
SW3 160
UART2_3_RS232_FOFF_N 164
This patch allows uncommenting an IXORA define in the board header file
in order to make use of those repurposed pins.
Please note that those pins are usually used for the 8-bit MMC/SD slot
aka Apalis MMC1 and the SDHCI controller/driver unfortunately changes
the output driver behaviour in a way preventing any regular GPIO use.
This patch therefore explicitly does not register the SDHCI driver on
this controller instance in the Ixora case to avoid this.

Turns out the Tegra 3 USB PHY driver had some hard coded dependency on
the Tegra OTG driver but we usually just use our own OTG driver purely
relying on a cable detect GPIO to determine USB device vs. host role.

Unfortunately that utmi_phy_remotewake_detected() function gets called
one too many times even quite continuously during data transfers and
putting an mdelay() in there has a rather adverse effect on the overall
system performance including of course degrading USB transfer speeds.
Moving the system lock-up avoidance hack further down into the if
clause improves the performance again as this typically is only ever
evaluated once upon actually plugging something in behind a hub.
This fixes a performance regression introduced by the following commit:

Add a comment about DAP FS pin mux requiring INPUT when operating as I2S slave.
Add a comment about DAP SCLK requiring INPUT even when operating as I2S master.
Add a comment about is_i2s_master in the platform data meaning T30 SoC is I2S
master.

A customer reported rare boot lock-ups every odd 500 software reboot

early clock initialisation as the boot loader anyway already
initialised the same.

It looks like our crystal load capacitance is way off as we just copied
NVIDIA's default setting being the lowest possible 1.5 pF due to their
boards having 20 pF external caps while our hardware does not have any
external caps assembled and we should use the highest 12.5 pF setting.

Bring the kernel module configuration more in line with what we
currently really deploy. As a second step we can then change the way
kernel modules are actually deployed by just deploying them all.

As NVIDIA so far was unable to provide us with any proper speedo
numbers for their industrial temperature aka IT parts just make SKU
0xB0 aka T30IQS-Ax behave identical to the regular commercial
temperature 0xB1 aka T30MQS-Ax for the SKU to speedo ID conversion.
This prevents them to fall back to fixed 600 MHz operation and crashing
thermal throttling once kicking in due to missing table entry causing a
null pointer exception.

This patch adds optional UHS support for the 8-bit MMC controller.
Please note that this requires V1.1A or later module hardware plus the
pull-up resistors on the data as well as the command signal lines of
your carrier board need to be removed (e.g. R46 to R54 on our Apalis
Evaluation Board V1.1A). If those pre-requisites are met support can be
enabled using the following kernel command line parameter:
mmc_uhs=1

Certain low-speed USB devices were not detected correctly when plugged
into a running system.

Both the Apalis EvalBoard as well as Ixora allow their LTC2954
pushbutton on/off controller to optionally initiate orderly shutdown
via GPIO interrupt on GPIO5 upon short power button press (short here
meaning really short unless C137 resp. C35 is assembled). For this to
work the following wiring is required:
Apalis EvalBoard V1.1a X61-4 to X2-6
Ixora V1.0a X5-4 to X27-17
For systemd/logind to actually use this as a power-switch a custom udev
rule /etc/udev/rules.d/70-power-switch-apalis_t30.rules as follows is
required:
# Specific rule for apalis_t30:
#
# Apalis T30's power button is not part of the kernel acpi subsystem.
# Let's manually add the power-switch tag to control its behaviour with
# systemd/logind
