As commented by Tomasz on gerrit, there is a pre-existing typo here.
Specifically "rockchip,rk3288-edp" should be "rockchip,rk3288-dp".

The typo is pre-existing so I'm not sure you would need to spin this
series to fix it, but if you were spinning it anyway it wouldn't hurt
to fix.  Could also just send out a followon patch to fix this after
the series lands...
