A clock input to a device should be named after the usage in the device, not after the clock that drives it. On the rk3568 the same clock is driven by the HPLL. This patch adds "ref" as a new alternative clock name for "vpll" Changes since v3: - Keep old clock name for compatibility reasons Signed-off-by: Sascha Hauer Acked-by: Rob Herring --- .../bindings/display/rockchip/rockchip,dw-hdmi.yaml | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/display/rockchip/rockchip,dw-hdmi.yaml b/Documentation/devicetree/bindings/display/rockchip/rockchip,dw-hdmi.yaml index 6e09dd2ee05a..638119924ad8 100644 --- a/Documentation/devicetree/bindings/display/rockchip/rockchip,dw-hdmi.yaml +++ b/Documentation/devicetree/bindings/display/rockchip/rockchip,dw-hdmi.yaml @@ -37,7 +37,8 @@ properties: # order when present. - description: The HDMI CEC controller main clock - description: Power for GRF IO - - description: External clock for some HDMI PHY + - description: External clock for some HDMI PHY (old clock name, deprecated) + - description: External clock for some HDMI PHY (new name) clock-names: minItems: 2 @@ -48,10 +49,14 @@ properties: - cec - grf - vpll + - ref - enum: - grf - vpll - - const: vpll + - ref + - enum: + - vpll + - ref ddc-i2c-bus: $ref: /schemas/types.yaml#/definitions/phandle
