2022-12-07mfd: stpmic1: Fix swapped mask/unmask in irq chipAidan MacDonald
The usual behavior of mask registers is writing a '1' bit to disable (mask) an interrupt; similarly, writing a '1' bit to an unmask register enables (unmasks) an interrupt. Due to a longstanding issue in regmap-irq, mask and unmask registers were inverted when both kinds of registers were present on the same chip, ie. regmap-irq actually wrote '1's to the mask register to enable an IRQ and '1's to the unmask register to disable an IRQ. This was fixed by commit e8ffb12e7f06 ("regmap-irq: Fix inverted handling of unmask registers") but the fix is opt-in via mask_unmask_non_inverted = true because it requires manual changes for each affected driver. The new behavior will become the default once all drivers have been updated. The STPMIC1 has a normal mask register with separate set and clear registers. The driver intends to use the set & clear registers with regmap-irq and has compensated for regmap-irq's inverted behavior, and should currently be working properly. Thus, swap mask_base and unmask_base, and opt in to the new non-inverted behavior.

2022-12-07mfd: stpmic1: Remove #ifdef guards for PM related functionsPaul Cercueil
Use the new DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20221118224540.619276-463-uwe@kleine-koenig.org
