8536a5ef88 ARM: 9169/1: entry: fix Thumb2 bug in iWMMXt exception handling
The Thumb2 version of the FP exception handling entry code treats the
register holding the CP number (R8) differently, resulting in the iWMMXT
CP number check to be incorrect.

Fix this by unifying the ARM and Thumb2 code paths, and switch the
order of the additions of the TI_USED_CP offset and the shifted CP
index.

9cf72c358a ARM: support for IRQ and vmap'ed stacks
This PR covers all the work related to implementing IRQ stacks and
 vmap'ed stacks for all 32-bit ARM systems that are currently supported
 by the Linux kernel, including RiscPC and Footbridge. It has been
 submitted for review in three different waves:
 - IRQ stacks support for v7 SMP systems [0],
 - vmap'ed stacks support for v7 SMP systems[1],
 - extending support for both IRQ stacks and vmap'ed stacks for all
   remaining configurations, including v6/v7 SMP multiplatform kernels
   and uniprocessor configurations including v7-M [2]

b0343ab330 ARM: reduce the information printed in call traces
A while back, Linus complained about the numeric values printed by the
ARM backtracing code. Printing these values does not make sense if one
does not have access to the kernel ELF image (as is normally the case
when helping a third party on a mailing list), but if one does, they
can be very useful to find the code, rather than searching for the
function name, and then doing hex math to work out where the backtrace
entry is referring to.

Provide an option to control whether this information is included,
which will only be visible if EXPERT is enabled.

a92882a4d2 ARM: 9159/1: decompressor: Avoid UNPREDICTABLE NOP encoding
In the decompressor's head.S we need to start with an instruction that
is some kind of NOP, but also mimics as the PE/COFF header, when the
kernel is linked as an UEFI application. The clever solution here is
"tstne r0, #0x4d000", which in the worst case just clobbers the
condition flags, and bears the magic "MZ" signature in the lowest 16 bits.

However the encoding used (0x13105a4d) is actually not valid, since bits
[15:12] are supposed to be 0 (written as "(0)" in the ARM ARM).
Violating this is UNPREDICTABLE, and *can* trigger an UNDEFINED
exception. Common Cortex cores seem to ignore those bits, but QEMU
chooses to trap, so the code goes fishing because of a missing exception
handler at this point. We are just saved by the fact that commonly (with
-kernel or when running from U-Boot) the "Z" bit is set, so the
instruction is never executed. See [0] for more details.

To make things more robust and avoid UNPREDICTABLE behaviour in the
kernel code, lets replace this with a "two-instruction NOP":
The first instruction is an exclusive OR, the effect of which the second
instruction reverts. This does not leave any trace, neither in a
register nor in the condition flags. Also it's a perfectly valid
encoding. Kudos to Peter Maydell for coming up with this gem.

c73960bb0a gpiolib: allow line names from device props to override driver names
Some GPIO providers set names for GPIO lines that match the names of
the pins on the SoC, or variations on that theme. These names are
generic more often that not, such as pioC12 in the at91 case. These
generic names block the possibility to set more useful GPIO line
names with device properties (i.e. gpio-line-names).

Allow overriding a generic name given by the GPIO driver if there is
a name given to the GPIO line using device properties, but leave the
generic name alone if no better name is available.

However, there is a risk. If user space is depending on the above
mentioned fixed GPIO names, AND there are device properties that
previously did not reach the surface, the name change might cause
regressions. But hopefully this stays below the radar...

Software nodes allow us to represent hierarchies for device components

banks of GPIOs under a common GPIO expander. The core gpiolib core
however doesn't offer any way of passing this information from the
drivers.

This extends struct gpio_chip with a pointer to fwnode that can be set
by the driver and used to pass device properties for child nodes.

This is similar to how we handle device-tree sub-nodes with
CONFIG_OF_GPIO enabled.

Support new nvidia,fixed-parent-rate device-tree property which instructs
I2S that board wants parent clock rate to stay at a fixed rate. This allows
to play audio over S/PDIF and I2S simultaneously. The root of the problem
is that audio components on Tegra share the same audio PLL, and thus, only
a subset of rates can be supported if we want to play audio simultaneously.
Filter out audio rates that don't match parent clock rate if device-tree
has the nvidia,fixed-parent-rate property.

ASoC: tegra20: spdif: Improve driver's code
- Clean up whitespaces, defines and variables.

- Remove obsolete code.

- Adhere to upstream coding style.

- Don't override returned error code.

- Replace pr_err with dev_err.

No functional changes are made by this patch. This is a minor code's
refactoring that will ease further maintenance of the driver.

ASoC: SOF: Kconfig: Make the SOF_DEVELOPER_SUPPORT depend on SND_SOC_SOF
SND_SOC_SOF_DEVELOPER_SUPPORT contains options affecting how the built
SOF driver stack will behave, enables debug options and other features.

These options have no meaning if the SND_SOC_SOF is not even enabled.

If we have SOF client options under developer_support and debug they can
be selected to be built even without the core, but they do need symbols
from the core (the sof-client API) which can result build failure.

In Kconfig we can have
SND_SOC_SOF_TOPLEVEL=y
SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST=y

for example, which will make the flood client to be built, but the SOF core
is not as SND_SOC_SOF is not selected.

ASoC: SOF: ipc: Add null pointer check for substream->runtime
When pcm stream is stopped "substream->runtime" pointer will be set
to NULL by ALSA core. In case host received an ipc msg from firmware
of type IPC_STREAM_POSITION after pcm stream is stopped, there will
be kernel NULL pointer exception in ipc_period_elapsed(). This patch
fixes it by adding NULL pointer check for "substream->runtime".

And resuming is handled by the ALSA core with the .prepare and

component driver trigger op. So, remove handling the RESUME trigger in
the platform trigger op for HDA platforms.
