I'm happy to do so, but I have just stumbled over a problem with
actually building the dtb for testing - it fails with
arch/arm/boot/dts/sun6i-a31s-primo81.dts:242.1-14 Label or path simplefb_lcd not found
The dts references simplefb_lcd:
+&simplefb_lcd {
+ vcc-lcd-supply = <®_dc1sw>;
+ vdd-mipi-bridge-supply = <®_eldo3>;
+};
but I don't see where it would be defined. This is on the current
sunxi/for-next branch of
https://git.kernel.org/cgit/linux/kernel/git/mripard/linux.git
with the Primo81 dts patch on top. Am I perhaps missing some
required additional patch here?
