It seems there is not mali node in sun7i-a20.dtsi
Add mali node to sun7i-a20.dtsi
This patch adds device tree mali node compatible with r6p2 utgard kernel driver
provided by ARM and patched by maxime ripard on his github.
It can be easily used in target.dts with:
&mali {
status = "okay";
}
then loading mali.ko in user space.
