[PATCH v2 2/6] mfd: rk8xx: Specify restart mode

From: Benjamin Bara
Date: Wed Aug 09 2023 - 15:25:43 EST


From: Benjamin Bara <benjamin.bara@xxxxxxxxxxx>

The current restart handler registration does not specify whether the
restart is a cold or a warm one. Instead, cold ones are typically
registered with a HIGH prio. Now, as do_kernel_restart() knows about the
type, the priorization is implicitly done (cold restarts are executed
first) and the reboot_mode kernel parameter (which is currently mostly
ignored) can be respected.
