   4 Subject: [PATCH] ARM: sunxi: Register the A31 reset IP in init_time
   5
   6 The A31 has a reset IP that maintains a few other IPs in reset by
   7 default. Among these IPs are the UARTs, and most notably the timers. We
   8 thus need to register the reset driver before initializing the timers so
   9 that the reset timer can use the reset framework.
