-Subject: [PATCH] reset: Add Allwinner SoCs Reset Controller Driver
-
-The Allwinner A31 and most of the other Allwinner SoCs have an IP
-maintaining a few other IPs in the SoC in reset by default. Among these
-IPs are the A31's High Speed Timers, hence why we can't use the regular
-driver construct in every cases, and need to call the registering
-function directly during machine initialisation.
-
-Apart from this, the implementation is fairly straightforward, and could
-easily be moved to a generic MMIO-based reset controller driver if the
-need ever arise.
