-Subject: [PATCH] reset: Add of_reset_control_get
-
-In some cases, you might need to deassert from reset an hardware block that
-doesn't associated to a struct device (CPUs, timers, etc.).
-
-Add a small helper to retrieve the reset controller from the device tree
-without the need to pass a struct device.
-
