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.
