a25351e4c7 pwm: imx27: Workaround of the pwm output bug when decrease the duty cycle
Implement workaround for ERR051198
(https://www.nxp.com/docs/en/errata/IMX8MN_0N14Y.pdf)

PWM output may not function correctly if the FIFO is empty when a new SAR
value is programmed.

Description:
  When the PWM FIFO is empty, a new value programmed to the PWM Sample
  register (PWM_PWMSAR) will be directly applied even if the current timer
  period has not expired. If the new SAMPLE value programmed in the
  PWM_PWMSAR register is less than the previous value, and the PWM counter
  register (PWM_PWMCNR) that contains the current COUNT value is greater
  than the new programmed SAMPLE value, the current period will not flip
  the level. This may result in an output pulse with a duty cycle of 100%.

Workaround:
  Program the current SAMPLE value in the PWM_PWMSAR register before
  updating the new duty cycle to the SAMPLE value in the PWM_PWMSAR
  register. This will ensure that the new SAMPLE value is modified during
  a non-empty FIFO, and can be successfully updated after the period
  expires.

Write the old SAR value before updating the new duty cycle to SAR. This
avoids writing the new value into an empty FIFO.

This only resolves the issue when the PWM period is longer than 2us
(or <500kHz) because write register is not quick enough when PWM period is
very short.

Reproduce steps:
  cd /sys/class/pwm/pwmchip1/pwm0
  echo 2000000000 > period     # It is easy to observe by using long period
  echo 1000000000 > duty_cycle
  echo 1 > enable
  echo       8000 > duty_cycle # One full high pulse will be seen by scope

15effedc48 pwm: axi-pwmgen: Enable FORCE_ALIGN by default
Enable the FORCE_ALIGN flag by default in the AXI PWMGEN driver. This
flag makes the behavior of the PWM output consistent with the
description at the top of the driver file.

    * Limitations:
    * - The writes to registers for period and duty are shadowed until
    *   LOAD_CONFIG is written to AXI_PWMGEN_REG_RSTN, at which point
    *   they take effect.
    * - Writing LOAD_CONFIG also has the effect of re-synchronizing all
    *   enabled channels, which could cause glitching on other channels. It
    *   is therefore expected that channels are assigned harmonic periods
    *   and all have a single user coordinating this.

Without this flag, the PWM output does not change until the period of
all PWM output channels has run out, which makes the PWM impossible to
use in some cases because it takes too long to change the output.

2e82d58c7b pwm: axi-pwmgen: Rename 0x10 register
Rename the 0x10 register from REG_CONFIG to REG_RSTN. Also rename the
associated bit macros accordingly.

While touching this, move the bit macros close to the register address
macro for better organization.

According to [1], the name of the 0x10 register is REG_RSTN, and there
is a different register named REG_CONFIG (0x18). So we should not be
using REG_CONFIG for the 0x10 register to avoid confusion.

Compared to direct calls to pwmchip_get_drvdata() a dedicated function
has two upsides: A better name and the right type. So the code becomes
easier to read and the new function is harder to use wrongly.

Another side effect (which is the secret motivation for this patch, but
shhh) is that the driver becomes a bit easier to backport to kernel
versions that don't have devm_pwmchip_alloc() yet.

cc6a931d1f pwm: imx-tpm: Use correct MODULO value for EPWM mode
The modulo register defines the period of the edge-aligned PWM mode
(which is the only mode implemented). The reference manual states:
"The EPWM period is determined by (MOD + 0001h) ..." So the value that
is written to the MOD register must therefore be one less than the
calculated period length. Return -EINVAL if the calculated length is
already zero.
A correct MODULO value is particularly relevant if the PWM has to output
a high frequency due to a low period value.

RZ/G3S) the watchdog PM domain need to be powered on in the watchdog
restart handler. Currently, only the clocks are enabled in the watchdog
restart handler. To be able to also power on the PM domain we need to

the watchdog device as IRQ safe and register the watchdog PM domain
with GENPD_FLAG_IRQ_SAFE.

Register watchdog PM domain as IRQ safe. Along with it the always-on

Move the PM domain power on in rzg2l_cpg_pd_setup(). With this the
previously always-on power domains got
struct generic_pm_domain::{power_on, power_off} populated (and
registered with simple_qos_governor if #power-domain-cells = <1> and
with pm_domain_always_on_gov if #power-domain-cells = <0>). The values for
struct generic_pm_domain::{power_on, power_off} are now populated for
all registered domains but used by core only for the domains that can
use them (the PM domain should be non always-on and registered with
simple_qos_governor). Moreover, the power on/off functions check if the
mstop support is valid. The mstop is populated only by the RZ/G3S
initialization code at the moment.

This approach was chosen to keep the code simple and use the same code
across different implementations. There should be no issues with this
approach as the always on domains are registered with GENPD_FLAG_ALWAYS_ON
and the PM domain core takes care of it.

This approach allows doing further cleanups on the rzg2l_cpg power domain
registering code that will be handled by the next commit.

tasks for user space such as sample rate converters, compressed
stream decoders, etc.

This is description for the API extension for the compress ALSA API which
is able to handle "tasks" that are not bound to real-time operations
and allows for the serialization of operations.

For details, refer to "compress-accel.rst" document.

5251ae224d ata: libata-scsi: Return residual for emulated SCSI commands
The function ata_scsi_rbuf_fill() used to fill the reply buffer of
emulated SCSI commands always copies the ATA reply buffer
(ata_scsi_rbuf) up to the size of the SCSI command buffer (the transfer
length for the command), even if the reply is shorter than the SCSI
command buffer. This leads to issuers of the SCSI command to always get
a result without any residual (resid is always 0) despite the
potentially shorter reply for the command.

Modify all fill actors used by ata_scsi_rbuf_fill() to return the number
of bytes filled for the reply and 0 in case of error. Using this value,
add a call to scsi_set_resid() in ata_scsi_rbuf_fill() to set the
correct residual for the SCSI command when the reply length is shorter
than the command buffer.

The data structure struct ata_scsi_args is used to pass the target ATA

increases the number of pointer dereferences for no gains.

36c2cf8880 cleanup: Add conditional guard helper
Add a new if_not_guard() macro to cleanup.h for handling
conditional guards such as mutext_trylock().

This is more ergonomic than scoped_guard() for most use cases.
Instead of hiding the error handling statement in the macro args, it
works like a normal if statement and allow the error path to be indented
while the normal code flow path is not indented. And it avoid unwanted
side-effect from hidden for loop in scoped_guard().

fcc22ac5ba cleanup: Adjust scoped_guard() macros to avoid potential warning
Change scoped_guard() and scoped_cond_guard() macros to make reasoning
about them easier for static analysis tools (smatch, compiler
diagnostics), especially to enable them to tell if the given usage of
scoped_guard() is with a conditional lock class (interruptible-locks,
try-locks) or not (like simple mutex_lock()).

Add compile-time error if scoped_cond_guard() is used for non-conditional
lock class.

Beyond easier tooling and a little shrink reported by bloat-o-meter
this patch enables developer to write code like:

int foo(struct my_drv *adapter)
{
	scoped_guard(spinlock, &adapter->some_spinlock)
		return adapter->spinlock_protected_var;
}

Current scoped_guard() implementation does not support that,
due to compiler complaining:
error: control reaches end of non-void function [-Werror=return-type]

Technical stuff about the change:
scoped_guard() macro uses common idiom of using "for" statement to declare
a scoped variable. Unfortunately, current logic is too hard for compiler
diagnostics to be sure that there is exactly one loop step; fix that.

To make any loop so trivial that there is no above warning, it must not
depend on any non-const variable to tell if there are more steps. There is
no obvious solution for that in C, but one could use the compound
statement expression with "goto" jumping past the "loop", effectively
leaving only the subscope part of the loop semantics.

More impl details:
one more level of macro indirection is now needed to avoid duplicating
label names;
I didn't spot any other place that is using the
"for (...; goto label) if (0) label: break;" idiom, so it's not packed for
reuse beyond scoped_guard() family, what makes actual macros code cleaner.

There was also a need to introduce const true/false variable per lock
class, it is used to aid compiler diagnostics reasoning about "exactly
1 step" loops (note that converting that to function would undo the whole
benefit).

Big thanks to Andy Shevchenko for help on this patch, both internal and
public, ranging from whitespace/formatting, through commit message
clarifications, general improvements, ending with presenting alternative
approaches - all despite not even liking the idea.

Big thanks to Dmitry Torokhov for the idea of compile-time check for
scoped_cond_guard() (to use it only with conditional locsk), and general
improvements for the patch.

Big thanks to David Lechner for idea to cover also scoped_cond_guard().

0d75e0c420 locking/osq_lock: Use atomic_try_cmpxchg_release() in osq_unlock()
Replace this pattern in osq_unlock():

    atomic_cmpxchg(*ptr, old, new) == old

... with the simpler and faster:

    atomic_try_cmpxchg(*ptr, &old, new)

The x86 CMPXCHG instruction returns success in the ZF flag,
so this change saves a compare after the CMPXCHG.  The code
in the fast path of osq_unlock() improves from:

Guard functions in local_lock.h are defined using DEFINE_GUARD() and
DEFINE_LOCK_GUARD_1() macros having lock type defined as pointer in
the percpu address space. The functions, defined by these macros
return value in generic address space, causing:

cleanup.h:157:18: error: return from pointer to non-enclosed address space

and

cleanup.h:214:18: error: return from pointer to non-enclosed address space

when strict percpu checks are enabled.

Add explicit casts to remove address space of the returned pointer.

Found by GCC's named address space checks.

WCN6855 (also known as QCA6490) is similar to the already supported
QCA6390 but takes in two more supplies so add a new vregs list for it.

On sm8450-hdk it also requires a short assert of the xo-clk pin so add
handling for it in a dedicated unit.

As we now have a separate set of targets for this variant, store the
pointer to the targets struct associated with a model in the device
match data.

How is the Orange Pi 5B unique?
  - the Orange Pi 5b uses combphy0_ps for the WiFi.
  - the Orange Pi 5B has GPIO0_C5 hooked to BT_WAKE_HOST.
  - builtin eMMC storage
  - ap6275p Wifi module (like the Orange Pi 5 Plus)
