Instead of passing a global GPIO number, pass a descriptor looked
up with the standard devm_gpiod_get_index_optional() call.
This driver has supported passing a LDO enable GPIO for years,
yet this facility has never been put to use in the upstream kernel.
If someone desires to put in place GPIO control for the LDOs,
this can be done by adding a GPIO descriptor table in the MFD
nexus in drivers/mfd/lp8788.c for the LDO device when spawning the
MFD children, or using a board file.

Instead of passing a global GPIO number for the enable GPIO, pass
a descriptor looked up from the device tree node or the board file
decriptor table for the regulator.
There is a single board file passing the GPIOs for LDO1 and LDO2
through platform data, so augment this to pass descriptors
associated with the i2c device as well.
The special GPIO enable DT property for the enable GPIO is
nonstandard but this was accomodated in
commit 6a537d48461deacc57c07ed86d9915e5aa4b3539
"gpio: of: Support regulator nonstandard GPIO properties".

When AXP806 support was added, POK was incorrectly expanded to PWROK.
However, the datasheet lists them as POK[LSNP], which is the same as
on the AXP288. Furthermore, the registers associated with POK functions
are the same as the PEK on the other AXP PMICs. This suggests that
"POK" means "Power On Key", much like "PEK" means "Power Enable Key",
instead of "Power OK".
This patch changes the "PWROK" prefix to "POK" for these interrupts.

Now GPIOD has support for both pdata systems and for non-standard DT
bindings the Arizona reset GPIO can be converted to use it. Worth
noting gpiod_set_raw_value_cansleep is used to match the behaviour
of the old GPIOs. This is because the part is fairly widely used and
it is unknown how many DTs are correctly setting active low through
device tree, so to avoid breaking any existing users it is best to
match the previous behaviour.

This reverts commit e04653a9dcf4d98defe2149c885382e5cc72082f.
It is no longer needed to install Chrome EC GPE handler to have
GPE enabled in suspend to idle path. It is found that with this
handler installed, EC wake up doesn't work because default EC
event handler that can wake up system is not getting called.

Commit 2dc4940360d4 ("regulator: tps65218: Remove all the compatibles")
changes the probe function of drivers/regulator/tps65218-regulator.c so
that it iterates through all available regulators and assumes that the
regulator IDs are sequential and match the order present in the enum
tps65218_regulator_id. However, for some reason the much older commit
c0ea88b890d6 ("regulator: tps65218: add support for LS3 current
regulator") updated all arrays with LS3 at the end but added it second
to last for the enum.
Because of this long standing mismatch in order between the
tps65218_regulator_id enum and the regulator_desc array in the tps65218
regulator driver, the new probe function causes the strobe values to be
associated with the wrong regulator ID. This causes LDO1 to fail to
suspend in tps65218_pmic_set_suspend_disable due to not having anything
probes for its strobe value. Fix the order in the enum so the probe
function works as the update intended.

Using input prescaler, capture unit will trigger DMA once every

Add support for PMW input mode on pwm-stm32. STM32 timers support
period and duty cycle capture as long as they have at least two PWM
channels. One capture channel is used for period (rising-edge), one
for duty-cycle (falling-edge).
When there's only one channel available, only period can be captured.
Duty-cycle is simply zero'ed in such a case.
Capture requires exclusive access (e.g. no pwm output running at the
same time, to protect common prescaler).
Timer DMA burst mode (from MFD core) is being used, to take two
snapshots of capture registers (upon each period rising edge).

STM32 Timers can support up to 7 DMA requests:
- 4 channels, update, compare and trigger.
Optionally request part, or all DMAs from stm32-timers MFD core.
Also add routine to implement burst reads using DMA from timer registers.
This is exported. So, it can be used by child drivers, PWM capture
for instance (but not limited to).

The AB8540 was an evolved version of the AB8500, but it was never
mass produced or put into products, only reference designs exist.
The upstream support was never completed and it is unlikely that
this will happen so drop the support for now to simplify
maintenance of the AB8500.

The X-Powers AXP813 PMIC is really close to what is already done for
AXP20X/AXP22X.
There are two pairs of bits to set the rate (one for Voltage and Current
measurements and one for TS/GPIO0 voltage measurements) instead of one.
The register to set the ADC rates is different from the one for
AXP20X/AXP22X.
GPIO0 can be used as an ADC (measuring Volts) unlike for AXP22X.
The scales to apply to the different inputs are unlike the ones from
AXP20X and AXP22X.

Commit 8275b77a1513 ("mfd: rts5249: Add support for RTS5250S power
saving") adds powersaving support for device-ids 5249 524a and 525a.
But as a side effect it breaks ASPM support for all the other device-ids,
causing e.g. the Haswell CPU on a Lenovo T440s to not go into a higher
c-state then PC3, while previously it would go to PC7, causing the
machine to idle at 7.4W instead of 6.6W!
The problem here is the new option.dev_aspm_mode field, which only gets
explicitly initialized in the new code for the device-ids 5249 524a and
525a. Leaving the dev_aspm_mode 0 for the other device-ids.
The default dev_aspm_mode 0 is mapped to DEV_ASPM_DISABLE, but the
old behavior of calling rtsx_pci_enable_aspm() when idle and
rtsx_pci_disable_aspm() when busy happens when dev_aspm_mode ==
DEV_ASPM_DYNAMIC.
This commit changes the enum so that 0 = DEV_ASPM_DYNAMIC matching the
old default behavior, fixing the pm regression with the other device-ids.

Because Realtek card reader drivers are pcie and usb drivers,
and they bridge mmc subsystem and memstick subsystem, they are
not mfd drivers. Greg and Lee Jones had a discussion about
where to put the drivers, the result is that misc is a good
place for them, so I move all files to misc. If I don't move
them to a right place, I can't add any patch for this driver.

Pull sound updates from Takashi Iwai:
"There are no big surprising changes in this cycle, yet not too boring,
either. The biggest change from diffstat POV is the removal of the
legacy OSS driver codes that have been already disabled for a long
time. This will bring a few trivial merge conflicts.
As new features in ASoC side, there are two things: a new AC97 bus
implementation and AMD Stony platform support. Both include the
relevant changes shared with other subsystems, e.g. AC97 MFD changes
and DRM AMD changes.
Some other highlighted topics are:
- A bunch of USB-audio drivers got the hardening against the
malicious device accesses with a new helper code for endpoint
sanity check
- Lots of cleanups for ASoC Intel platform code, including support
for their open source audio firmware
- Continued ASoC core componentization works
- Support for scaling MCLK with sample rate in ASoC simple-card
- Stabler PCM hot-unplug capability, especially for ASoC usages"
