[PATCH 3/3] arm64: dts: qcom: sm7225-fairphone-fp4: Enable display and GPU

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add the description for the display panel found on this phone and remove
the simple-framebuffer that was in place until now. Unfortunately the
LCDB module on PM6150L isn't yet supported upstream so we need to use a
dummy regulator-fixed in the meantime.

And with this done we can also enable the GPU.
