+Subject: [PATCH] ARM: sunxi: Register the A31 reset IP in init_time
+
+The A31 has a reset IP that maintains a few other IPs in reset by
+default. Among these IPs are the UARTs, and most notably the timers. We
+thus need to register the reset driver before initializing the timers so
+that the reset timer can use the reset framework.
