Series queued for v5.4...

> Neil Armstrong (5):
>   dt-bindings: power: add Amlogic Everything-Else power domains bindings
>   soc: amlogic: Add support for Everything-Else power domains controller

These two in v5.4/drivers,

>   arm64: meson-g12: add Everything-Else power domain controller
>   arm64: dts: meson-sm1-sei610: add HDMI display support
>   arm64: dts: meson-sm1-sei610: add USB support

and these 3 in v5.4/dt64,

Thanks,
