The SATA PHY in Exynos5250 SoCs has two interfaces and two device nodes: 1. sata-phy@12170000 2. i2c-9/i2c@38 The first node represents the actual SATA PHY device with phy-cells. The second represents additional I2C interface, needed by the driver to communicate with the SATA PHY device. It is not a PHY-provider in the terms of dtschema so rename it to silence dtbs_check warning: arch/arm/boot/dts/exynos5250-arndale.dt.yaml: sata-phy@38: '#phy-cells' is a required property From schema: lib/python3.6/site-packages/dtschema/schemas/phy/phy-provider.yaml Signed-off-by: Krzysztof Kozlowski <krzk@xxxxxxxxxx> --- arch/arm/boot/dts/exynos5250-arndale.dts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/exynos5250-arndale.dts b/arch/arm/boot/dts/exynos5250-arndale.dts index f2bcce167b2d..3c401c82905c 100644 --- a/arch/arm/boot/dts/exynos5250-arndale.dts +++ b/arch/arm/boot/dts/exynos5250-arndale.dts @@ -544,7 +544,7 @@ samsung,i2c-max-bus-freq = <40000>; samsung,i2c-slave-addr = <0x38>; - sata_phy_i2c: sata-phy@38 { + sata_phy_i2c: sata-phy-i2c@38 { compatible = "samsung,exynos-sataphy-i2c"; reg = <0x38>; }; -- 2.17.1
