Subject: [PATCH v1 04/17] dt-bindings: display: mediatek: add MT8195 hdmi bindings
Add mt8195 SoC bindings for hdmi and hdmi-ddc
Make port1 optional for mt8195 as it only supports HDMI tx for now.
Requires a ddc-i2c-bus phandle.
Requires a power-domains phandle.
Signed-off-by: Guillaume Ranquet <granquet@...libre.com>
