power: reset: keystone: Use syscon_regmap_lookup_by_phandle_args

2025-01-15T20:51:39+00:00

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument.  Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.

There is also no real benefit in printing errors on missing syscon
argument, because this is done just too late: runtime check on
static/build-time data.  Dtschema and Devicetree bindings offer the
static/build-time check for this already.

power: reset: as3722-poweroff: Remove unnecessary return in as3722_poweroff_probe

2024-12-18T23:38:11+00:00

The return is executed on the devm_register_sys_off_handler() line in
as3722_poweroff_probe, so the last return line is unnecessary. Remove it.

power: reset: gpio-poweroff: Clarify the warning message

2024-12-12T22:34:50+00:00

When gpio-poweroff fails, a WARN_ON() is triggered without
an explanation to the user about the failure.

Add some comments explaining that the attempt to poweroff the system
via gpio-poweroff failed and convert it to a WARN() message with a
bit of context to provide some hint to the user.

power: reset: ep93xx: add AUXILIARY_BUS dependency

power: Switch back to struct platform_driver::remove()

2024-10-21T13:51:42+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/power/ 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.

While touching these files, make indention of the struct initializer
consistent in several files.

power: reset: syscon-reboot: Accept reg property

2024-10-16T20:26:20+00:00

For historical reasons syscon-reboot has used an 'offset' property. As a
child on a MMIO bus having a 'reg' property is more appropriate. Accept
'reg' as an alternative to 'offset'.
