mfd: sec: 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: sec-core: Convert to i2c's .probe_new()

2022-12-07T13:27:24+00:00

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

mfd: sec: Enable wakeup from suspend via devicetree property

2021-06-02T09:51:18+00:00

Set device wakeup capability from devicetree property (done by drivers
core), instead of always setting it to 0 (because value in platform data
is not assigned).

This should not have visible effect on actual resuming from suspend
because the child device - S5M RTC driver - is responsible for waking
up and sets device wakeup unconditionally.

mfd: sec: Remove unused irq_base in platform data

2021-06-02T09:51:18+00:00

The 'irq_base' field of platform data structure is not assigned,
therefore its default value of 0 has no impact and can be safely
dropped.

mfd: sec: Drop support for board files and require devicetree

2021-06-02T09:51:18+00:00

The Samsung PMIC drivers since long time are used only on devicetree
platforms (Samsung Exynos) and there are no users with board files.

Drop the support for board files entirely and depend on OF for matching.

mfd: sec: Simplify getting of_device_id match data

2021-06-02T09:51:18+00:00

Use of_device_get_match_data() to make the code slightly smaller.  There
is also no need to wrap it in a check for CONFIG_OF, because dev.of_node
will be set only with OF support.

mfd: sec: Initialize driver via module_platform_driver()

2021-04-14T15:06:03+00:00

The driver was using subsys_initcall() because in old times deferred
probe was not supported everywhere and specific ordering was needed.
Since probe deferral works fine and specific ordering is discouraged
(hides dependencies between drivers and couples their boot order), the
driver can be converted to regular module_platform_driver.

The RTC portion of the S2MPA01 appears to have the same
