mfd: stpmic1: Convert to use maple tree register cache

2024-02-23T14:58:05+00:00

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.

mfd: stpmic1: Remove redundant of_match_ptr()

2023-08-22T07:07:51+00:00

The driver depends on CONFIG_OF, so it is not necessary to use
of_match_ptr() here. We remove of_match_ptr() here.

mfd: stpmic1: Add PMIC poweroff via sys-off handler

2023-06-15T08:19:39+00:00

Use devm_register_sys_off_handler() that allows to register multiple
power-off handlers.
This will allow boards using the stpmic1 to power-off.

mfd: Switch i2c drivers back to use .probe()

2023-06-15T08:19:37+00:00

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.

mfd: stpmic1: Fix swapped mask/unmask in irq chip

2022-12-07T13:28:15+00:00

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.

mfd: stpmic1: Remove #ifdef guards for PM related functions

2022-12-07T13:28:11+00:00

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.

mfd: stpmic1: Convert to i2c's .probe_new()

2022-12-07T13:27:25+00:00

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.
