Thanks for this work. As I said on IRC I've fettled the patches a bit
to get things applying properly. I reckon it's a good idea to add '9'
to the PATCH_MATCH as all these patches should be needed on 4.19 too,
and hopefully they stil apply.

I'll do an upload as soon as I've checked it still works on my firefly.

OK. Looks like that uses the standard ARM licence, unlike Allwiner who
made up their own version which does not allow debian
redistribution. Well done rockchip.

I'll include that in my packages. 

There is one more issue, but I'll start a new thread about that.
