   4 Subject: [PATCH] ARM: sun6i: Add the reset controller to the DTSI
   5
   6 The A31 has a reset controller IP that maintains a few other IPs in
   7 reset, among which we can find the UARTs, high speed timers or the I2C.
   8 Now that we have support for them, add the reset controllers to the DTSI.
