The i2c-ocores controller can run in interrupt mode on tqmx86 modules.
Add a module parameter to allow configuring the IRQ number, similar to the
handling of the GPIO IRQ.
The new code and module parameter refer to the I2C controller as "I2C1",
as the TQMx86 PLD actually contains a second I2C controller, for which
driver support will be added in the future.

GPIO IRQ setup can fail either because an invalid IRQ was passed as a
parameter, or because the GPIO controller does not support interrupts.
Neither is severe enough to stop the whole probe; simply disable IRQ
support in the GPIO resource when setup fails.
The code is made a bit more robust by introduing an enum for the
resource list indices instead of assuming that the IRQ is at index 0.

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/mfd to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
On the way do a few whitespace changes to make indention consistent.

A few ROHM PMICs have an RTC block which can be controlled by the
rtc-bd70528 driver. The RTC driver needs the alarm interrupt information
from the parent MFD driver. The MFD driver provides the interrupt
information as a set of named interrupts, where the name is of form:
<PMIC model>-rtc-alm-<x>, where x is an alarm block number.
>From the RTC driver point of view it is irrelevant what the PMIC name
is. It is sufficient to know this is alarm interrupt for a block X. The
PMIC model information is carried to RTC via the platform device ID.
Hence, having the PMIC model in the interrupt name is only making things
more complex because the RTC driver needs to request differently named
interrupts on different PMICs, making code unnecessary complicated.
Simplify this slightly by always using the RTC driver name 'bd70528' as
the prefix for alarm interrupts, no matter what the exact PMIC model is,
and always request the alarm interrupts of same name no matter what the
PMIC model is.

The ASoC CODEC driver masks the IRQs whilst entering and exiting
system suspend to avoid issues where the IRQ handler can run but PM
runtime is disabled. However, as the IRQs could also be used from
other parts of the driver, it would be better to move this handling to
the MFD level.
Remove the handling from the ASoC driver and move it to the MFD
driver. Whilst moving also ensure the IRQs are all masked at the device
level before powering down the device, as per hardware recommendations.

The X-Powers AXP323 is a very close sibling of the AXP313A. The only
difference seems to be the ability to dual-phase the first two DC/DC

Add the required boilerplate to introduce a new PMIC to the AXP MFD
driver. Where possible, this just maps into the existing structs defined
for the AXP313A, only deviating where needed.

The ROHM BD96801 "scalable PMIC" provides two physical IRQs. The ERRB
handling can in many cases be omitted because it is used to inform fatal
IRQs, which usually kill the power from the SOC.
There may however be use-cases where the SOC has a 'back-up' emergency
power source which allows some very short time of operation to try to
gracefully shut down sensitive hardware. Furthermore, it is possible the
processor controlling the PMIC is not powered by the PMIC. In such cases
handling the ERRB IRQs may be beneficial.

The error path in cs42l43_boot_work() will lead to an unbalanced
regulator put, when the driver is removed. Fix this by relying
on remove to power down the device. Also the boot work needs to
be synchronised with driver remove, to ensure the work is not
still running after the driver has been removed. Add the required
cancel_work_sync().

be added in subsequent patch. The device also has ADC for power and

Driver has mixed up the R/W bit.
The LSB bit is set on write rather than read.
Change it to avoid nasty things to happen.

As the comment said, disable_irq() after request_irq() still has a
time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN
flag will disable IRQ auto-enable when request IRQ.

syscon has always set the optional max_register configuration of
regmap to ensure the correct checks are in place. However, a recent
commit 0ec74ad3c1 ("regmap: rework ->max_register handling")
introduced explicit configuration in regmap framework for register
maps that is exactly 1 register, when max_register is pointing to a
valid register 0. This commit solved a previous limitation of regmap
framework.
Update syscon driver to consistent in regmap configuration for
all sizes of syscons by using this new capability by setting
max_register_is_0, when the max_register is valid and 0.

asm/unaligned.h is always an include of asm-generic/unaligned.h;
