-Subject: [PATCH] reset: Add Allwinner A31 Reset Controller Driver
-
-The Allwinner A31 has an IP maintaining a few other IPs in the SoC in
-reset by default. Among these IPs are the High Speed Timers, hence why
-we can't use the regular driver construct, and need to call the
-registering function directly during machine initialisation.
