This patch introduces the clock required for the audio codec. This clock provides the I2S master clock for the audio data. The codec driver finds the clock by the name "mclk" and will fail to register if this is missing. Clock-names is kept here to keep compatibility with the exisitng driver ABI and also to be consistent with the rk817 binding. This series fixes the following warning from dtb check: pmic@20: '#sound-dai-cells', 'assigned-clock-parents', 'assigned-clocks', 'clock-names', 'clocks', 'codec' do not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Tim Lunn --- Changes in v3: - split out clocks into separate patch and group example properties where properties are introduced. - Address review comments - drop clock descriptions that arent required - set maxitems on clocks Changes in v2: - Fix missing include and pinctrl for codec example .../devicetree/bindings/mfd/rockchip,rk809.yaml | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/mfd/rockchip,rk809.yaml b/Documentation/devicetree/bindings/mfd/rockchip,rk809.yaml index be0616201f52..0174261449ab 100644 --- a/Documentation/devicetree/bindings/mfd/rockchip,rk809.yaml +++ b/Documentation/devicetree/bindings/mfd/rockchip,rk809.yaml @@ -93,6 +93,13 @@ properties: unevaluatedProperties: false unevaluatedProperties: false + clocks: + maxItems: 1 + + clock-names: + items: + - const: mclk + '#sound-dai-cells': const: 0 @@ -135,6 +142,7 @@ additionalProperties: false examples: - | + #include #include #include #include @@ -149,8 +157,10 @@ examples: clock-output-names = "xin32k", "rk808-clkout2"; interrupt-parent = <&gpio3>; interrupts = <10 IRQ_TYPE_LEVEL_LOW>; + clock-names = "mclk"; + clocks = <&cru SCLK_I2S1_OUT>; pinctrl-names = "default"; - pinctrl-0 = <&pmic_int_l_pin>; + pinctrl-0 = <&pmic_int_l_pin>, <&i2s1_2ch_mclk>; rockchip,system-power-controller; wakeup-source; #sound-dai-cells = <0>;
