A new compatible string is reserved in the binding documentation, to be used together with the proper fall back. Tested on Teres-I. Signed-off-by: Harald Geyer Reviewed-by: Rob Herring --- changes since v1: * add and use an A64 specific compatible string * claim the full memory range 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 additionally add support for r_pwm 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.
