power: reset: ep93xx: add AUXILIARY_BUS dependency

2024-11-11T23:07:00+00:00

This fails to link when compile-testing and the auxiliary bus is not built-in:

x86_64-linux-ld: drivers/power/reset/ep93xx-restart.o: in function `ep93xx_reboot_driver_init':
ep93xx-restart.c:(.init.text+0x11): undefined reference to `__auxiliary_driver_register'
x86_64-linux-ld: drivers/power/reset/ep93xx-restart.o: in function `ep93xx_reboot_driver_exit':
ep93xx-restart.c:(.exit.text+0x8): undefined reference to `auxiliary_driver_unregister'

Add the appropriate dependency.

reset: keystone-reset: remove unused macros

2024-11-11T21:56:35+00:00

After reviewing the code, it was found that these macros are never
referenced in the code. Just remove them.

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'.
