The "virtio_mmio.device=" command line argument allows a user to specify
the size, address, and IRQ of a virtio device. Previously the only
requirement for the IRQ was that it be an unsigned integer.
Zero is an unsigned integer but an invalid IRQ number, and after
a85a6c86c2 ("driver core: platform: Clarify that IRQ 0 is invalid"),
attempts to use IRQ 0 cause warnings.
If the user specifies IRQ 0, return failure instead of registering a device
with IRQ 0.

There are two merge commits in here of immutable branches that may
also be picked up through other trees (clocksource and input)
I've put a few late breaking fixes in here that aren't worth rushing
in before the merge window. One major fix for an issue introduced
in the last set that can result in devices not having their parent set.
This set is dominated by W=1 cleanups from Lee Jones. I won't list them
all separately. They are mostly:
* Kernel doc fixes
* Unused variable removal.
* Suppression of unused stuff that is static in headers.
Counters subsystem
* atmel-tcb
- New counter driver after various cleanups of existing tcb code and bindings.
Device support
* stk311
- Trivial addition of ID for STK311-X variant.
yaml conversions
* kionix,kxsd9
* ti,ads8688
Features
* jz47xx
- Add support for touch screen channels. In this particular case the
boards in question actually wire a joystick to them so we want them
as simple voltage channels. The joystick driver will probably go
via the input tree.
Cleanups + fixes
* core
- A rebase issue in recent major refactoring dropped the assignment of
of the device parent in the core. Put it back.
* ad5592r
- Fix unbalanced mutex unlocks in *_read_raw()
* ad7124
- Move chip ID and name to the chip_info table plus add a read of the
revision register to check the device is working during probe.
* ad7192
- Ridy up ordering to put the match table near the end fo the file where it
is used.
* lsm6dsx
- Reset the hardware timestamp after a resume to avoid an issue with
missaligned timestamps after suspend.
* jz47xx
- Error checks on clk_enable() calls.
- xlate callaback to find channel index.
- Use separate chan_spec arrays for different variants rather than
parts of a single list. Simplifies code.

This change does the following:
* removes the SPI device table in favor of the OF device table
* adds 'name' && 'chip_id' fields to chip_info
* implements chip ID & silicon revision checking; the device ID for
AD7124-4 is 0x0, so just checking that value can be useless;
but at least the silicon revision isn't 0, so a non-zero value can be
used to check that "a" device is on the SPI bus; it's probably the best
way to narrow it down to one of the 2 AD7124 chip IDs

Commit 5bd70440cb ("ASoC: soc-dai: revert all changes to DAI
startup/shutdown sequence"), introduced a slight change of semantics
to DAI startup/shutdown. If startup() returns an error, shutdown()
is now called for the DAI.
This causes a deadlock in hdac_hda which issues a call to
snd_hda_codec_pcm_put() in case open fails. Upon error, soc_pcm_open()
will call shutdown(), and pcm_put() ends up getting called twice. Result
is a deadlock on pcm->open_mutex, as snd_device_free() gets called from
within snd_pcm_open(). Typical task backtrace looks like this:

The hdac_hda remove implementation fails to free the hda codec
resources, leading to memleaks at module unload. This gap has been there
from the start, commit 6bae5ea949 ("ASoC: hdac_hda: add asoc
extension for legacy HDA codec drivers").
Instead of duplicating the cleanup logic, use the common
snd_hda_codec_cleanup_for_unbind() to free the resources. Remove
existing code in hdac_hda to cleanup "codec.jackpoll_work" and call to
snd_hdac_regmap_exit(), as these are already done in
snd_hda_codec_cleanup_for_unbind().
The cleanup is done in ASoC component remove() callback and not in the
HDAC bus hdev_detach(). This is done to ensure the codec specific
cleanup routines are run before the parent card is freed.

Add support for the scv instruction on POWER9 and later CPUs.
For now this implements the zeroth scv vector 'scv 0', as identical to
'sc' system calls, with the exception that LR is not preserved, nor
are volatile CR registers, and error is not indicated with CR0[SO],
but by returning a negative errno.
rfscv is implemented to return from scv type system calls. It can not
be used to return from sc system calls because those are defined to
preserve LR.
getpid syscall throughput on POWER9 is improved by 26% (428 to 318
cycles), largely due to reducing mtmsr and mtspr.

added while adding the gpiochip.

The scv instruction causes an interrupt which can enter the kernel with
MSR[EE]=1, thus allowing interrupts to hit at any time. These must not
be taken as normal interrupts, because they come from MSR[PR]=0 context,
and yet the kernel stack is not yet set up and r13 is not set to the
PACA).
Treat this as a soft-masked interrupt regardless of the soft masked
state. This does not affect behaviour yet, because currently all
interrupts are taken with MSR[EE]=0.

for the LED and the ability to switch between SW control and the

[squashed leds: multicolor: Fix camel case in documentation in]
Starting in commit cbc7a6b5a8 ("ASoC: soc-card: add
snd_soc_card_add_dai_link()"), error value from ASoc add_dai_link() is
no longer ignored.
The generic HDA machine driver relied on the old semantics to disable
i915 HDMI/DP audio codec at runtime. If no display codec was present,
add_dai_link() returned an error, but this was ignored and rest of the
card was successfully probed.
Fix the problem by changing the machine driver add_dai_link() to not
return an error in this case.

PowerISA v3.1 has few updates for the Branch History Rolling
Buffer(BHRB).
BHRB disable is controlled via Monitor Mode Control Register A (MMCRA)
bit, namely "BHRB Recording Disable (BHRBRD)". This field controls
whether BHRB entries are written when BHRB recording is enabled by
other bits. This patch implements support for this BHRB disable bit.
By setting 0b1 to this bit will disable the BHRB and by setting 0b0 to
this bit will have BHRB enabled. This addresses backward
compatibility (for older OS), since this bit will be cleared and
hardware will be writing to BHRB by default.
This patch addresses changes to set MMCRA (BHRBRD) at boot for
power10 (there by the core will run faster) and enable this feature
only on runtime ie, on explicit need from user. Also save/restore
MMCRA in the restore path of state-loss idle state to make sure we
keep BHRB disabled if it was not enabled on request at runtime.

Commit bb19af8160 ("powerpc/perf: Prevent kernel address leak to
userspace via BHRB buffer") added a check in bhrb_read() to filter
the kernel address from BHRB buffer. This patch modified it to avoid
that check for PowerISA v3.1 based processors, since PowerISA v3.1
allows only MSR[PR]=1 address to be written to BHRB buffer.
