However, some I2C controllers defined in "arch/arm64/boot/dts/amd/" and "arch/arm64/boot/dts/hisilicon/" directories do not have child nodes. So they don't need these two properties and don't write them explicitly. Therefore, setting properties "#address-cells" and "#size-cells" as "required" in this yaml file causes the following warnings: /root/linux-next/arch/arm64/boot/dts/hisilicon/hi6220-hikey.dt.yaml: \ i2c@f7100000: '#address-cells' is a required property /root/linux-next/arch/arm64/boot/dts/hisilicon/hi6220-hikey.dt.yaml: \ i2c@f7100000: '#size-cells' is a required property Signed-off-by: Zhen Lei --- Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml | 8 -------- 1 file changed, 8 deletions(-) diff --git a/Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml b/Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml index 4f746bef23742e9..c22b66b6219eaa3 100644 --- a/Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml +++ b/Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml @@ -101,8 +101,6 @@ unevaluatedProperties: false required: - compatible - reg - - "#address-cells" - - "#size-cells" - interrupts examples: @@ -110,8 +108,6 @@ examples: i2c@f0000 { compatible = "snps,designware-i2c"; reg = <0xf0000 0x1000>; - #address-cells = <1>; - #size-cells = <0>; interrupts = <11>; clock-frequency = <400000>; }; @@ -119,8 +115,6 @@ examples: i2c@1120000 { compatible = "snps,designware-i2c"; reg = <0x1120000 0x1000>; - #address-cells = <1>; - #size-cells = <0>; interrupts = <12 1>; clock-frequency = <400000>; i2c-sda-hold-time-ns = <300>; @@ -148,8 +142,6 @@ examples: reg = <0x100400 0x100>, <0x198 0x8>; pinctrl-0 = <&i2c_pins>; pinctrl-names = "default"; - #address-cells = <1>; - #size-cells = <0>; interrupts = <8>; clocks = <&ahb_clk>; };
