[PATCH v2 1/9] dt-bindings: display: rockchip: analogix-dp: Expand clock-names "hclk" for the third clock

[Damon Ding]

The RK3588 eDP controller needs the video datapath clock "hclk" to work
well. Previously, it works without explicitly adding this clock because
the 'rockchip,vo-grf = <&vo1_grf>' property implicitly enables HCLK_VO1.

Fixes: f855146263b1 ("dt-bindings: display: rockchip: analogix-dp: Add support for RK3588")
