The newly added 'apb' reset is to ensure the APB bus of eDP controller works well on the RK3588 SoC. Signed-off-by: Damon Ding --- Changes in v2: - Add the main defferences of the RK3588 eDP and the previous versions in commit message Changes in v3: - Expand the property clock-names, resets and reset-names Changes in v4: - Remove 'spdif' clock which added in v3 - Add the comment of newly added 'apb' reset in commit message Changes in v5: - Put the differences between RK3288/RK3399 and RK3588 into 'allOf' --- .../rockchip/rockchip,analogix-dp.yaml | 37 ++++++++++++++++--- 1 file changed, 31 insertions(+), 6 deletions(-) diff --git a/Documentation/devicetree/bindings/display/rockchip/rockchip,analogix-dp.yaml b/Documentation/devicetree/bindings/display/rockchip/rockchip,analogix-dp.yaml index eaf4e67e232e..3cdea9e63522 100644 --- a/Documentation/devicetree/bindings/display/rockchip/rockchip,analogix-dp.yaml +++ b/Documentation/devicetree/bindings/display/rockchip/rockchip,analogix-dp.yaml @@ -15,6 +15,7 @@ properties: enum: - rockchip,rk3288-dp - rockchip,rk3399-edp + - rockchip,rk3588-edp clocks: minItems: 2 @@ -30,12 +31,6 @@ properties: power-domains: maxItems: 1 - resets: - maxItems: 1 - - reset-names: - const: dp - rockchip,grf: $ref: /schemas/types.yaml#/definitions/phandle description: @@ -55,6 +50,36 @@ required: allOf: - $ref: /schemas/display/bridge/analogix,dp.yaml# + - if: + properties: + compatible: + contains: + enum: + - rockchip,rk3288-dp + - rockchip,rk3399-edp + then: + properties: + resets: + maxItems: 1 + reset-names: + const: dp + + - if: + properties: + compatible: + contains: + enum: + - rockchip,rk3588-edp + then: + properties: + resets: + minItems: 2 + maxItems: 2 + reset-names: + items: + - const: dp + - const: apb + unevaluatedProperties: false examples:
