The HDMI DDC driver for both mt7623 and mt8167 is actually the same as mt8173-hdmi-ddc and the mt7623n.dtsi board include file already uses mt8173-hdmi-ddc compatible as a fallback, but the documentation lists them as separate entries. Correct the binding by adding the correct fallback.
Fixes the following dtbs_check error in mt7623n-rfb-emmc.dts and mt7623n-bananapi-bpi-r2.dts: i2c@11013000 (mediatek,mt7623-hdmi-ddc): compatible: ['mediatek,mt7623-hdmi-ddc', 'mediatek,mt8173-hdmi-ddc'] is too long Signed-off-by: Luca Leonardo Scorcia <[email protected]> Reviewed-by: Krzysztof Kozlowski <[email protected]> --- Changes in v2: Simplified error description in commit message.
