[PATCH 0/3] arm64: dts: meson: fixups for WeTek common dtsi

[Christian Hewitt]

Two fixes from work on u-boot support and following access to the original
vendor schematics, plus a minor change to use revised LED bindings.

- Mark VDDIO_AO18 always-on and link hdmi-supply to fix HDMI on boot
- Add missing GPIO binding
- Update LED bindings

[PATCH 1/3] arm64: dts: meson-gxbb-wetek: fix HDMI in early boot

[Christian Hewitt]

Mark the VDDIO_AO18 regulator always-on and set hdmi-supply for the hdmi_tx
node to ensure HDMI is powered in the early stages of boot.

[PATCH 2/3] arm64: dts: meson-gxbb-wetek: fix missing GPIO binding

[Christian Hewitt]

The absence of this binding appears to be harmless in Linux but it breaks
Ethernet support in mainline u-boot. So add the binding (which is present
in all other u-boot supported GXBB device-trees).

Fixes: fb72c03e0e32 ("ARM64: dts: meson-gxbb-wetek: add a wetek specific dtsi to cleanup hub and play2")
