[PATCH v2 4/6] mfd: tps65219: Specify restart mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
