power: reset: odroid-go-ultra: fix I2C dependency

2023-02-15T22:49:40+00:00

Since this driver can only be built-in, it fails to link when
the I2C layer is in a loadable module:

x86_64-linux-ld: drivers/power/reset/odroid-go-ultra-poweroff.o: in function `odroid_go_ultra_poweroff_get_pmic_device':
odroid-go-ultra-poweroff.c:(.text+0x30): undefined reference to `i2c_find_device_by_fwnode'

Tighten the dependency to only allow enabling
POWER_RESET_ODROID_GO_ULTRA_POWEROFF is I2C is built-in as well.

power: reset: add Odroid Go Ultra poweroff driver

2023-02-14T22:02:39+00:00

The Hardkernel Odroid Go Ultra poweroff scheme requires requesting a poweroff
to its two PMICs in order, this represents the poweroff scheme needed to complete
a clean poweroff of the system.

This implement this scheme by implementing a self registering driver to permit
using probe defer until both pmics are finally probed.

drivers/power/reset/pwr-mlxbf.c:20:12: warning: symbol 'low_pwr_hid' was not declared. Should it be static?

Both rst_pwr_hid and low_pwr_hid are only used in a single function
so they should be local variables.
