[PATCH 4/5] arm64: dts: allwinner: a64: Add pwm device
From: Harald Geyer
Date: Mon Mar 12 2018 - 12:12:35 EST
This device is compatible with A13, so no new driver is needed.

I saw that Andre Przywara has been working on A64 pwm too and has
submitted some patches a few days ago. I think his patches are functionally
equivalent to this one here, but clean up things a bit and thus are
preferable. See:
https://groups.google.com/forum/#!topic/linux-sunxi/hQFeteP591k
I'm including my patch here mostly to have a consistent series for others
to test. OTOH you might merge the device tree changes here and pick up
the cleanup patches from him. Either way should work fine.
