again without this Signed-off please (also true for patch 5/6 where I forgot to 
mention it)

general rule, the more specific compatible should be in front, so
		compatible = "rockchip,rk3288-pmu-sram", "mmio-sram";

This way, if there is a driver for "rockchip,rk3288-pmu-sram" at some point in 
the future, it will grab the node before the more generic sram driver does.

But in general, what is the pmu sram necessary for, as no part of this series 
uses it?
