Commit Message

Maxime Ripard May 27, 2019, noon UTC 
The older Allwinner SoCs have an embedded RTC supported in Linux, with a
matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

-- interrupts: IRQ line for the RTC.
