2024-02-23mfd: stpmic1: Convert to use maple tree register cacheBo Liu1-1/+1
The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache.

2023-08-22mfd: stpmic1: Remove redundant of_match_ptr()Zhu Wang1-1/+1
The driver depends on CONFIG_OF, so it is not necessary to use of_match_ptr() here. We remove of_match_ptr() here. Signed-off-by: Zhu Wang <wangzhu9@huawei.com> Link: https://lore.kernel.org/r/20230808130023.202700-6-wangzhu9@huawei.com Signed-off-by: Lee Jones <lee@kernel.org>
2023-06-15mfd: stpmic1: Add PMIC poweroff via sys-off handlerSean Nyekjaer1-0/+21
Use devm_register_sys_off_handler() that allows to register multiple power-off handlers. This will allow boards using the stpmic1 to power-off.

2023-06-15mfd: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+1
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2022-12-07mfd: stpmic1: Fix swapped mask/unmask in irq chipAidan MacDonald1-2/+3
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 Cercueil1-4/+2
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.

2022-12-07mfd: stpmic1: Convert to i2c's .probe_new()Uwe Kleine-König1-3/+2
