The USDHC on i.MX 8M Mini has its own compatible described in bindings and used in the driver (with its own quirks). Remove additional fsl,imx7d-usdhc compatible to fix dtbs_check warnings like: arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: mmc@30b40000: compatible: ['fsl,imx8mm-usdhc', 'fsl,imx7d-usdhc'] is too long From schema: Documentation/devicetree/bindings/mmc/fsl-imx-esdhc.yaml arch/arm64/boot/dts/freescale/imx8mm-evk.dt.yaml: mmc@30b40000: compatible: Additional items are not allowed ('fsl,imx7d-usdhc' was unexpected) Signed-off-by: Krzysztof Kozlowski <krzk@xxxxxxxxxx> --- arch/arm64/boot/dts/freescale/imx8mm.dtsi | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/arch/arm64/boot/dts/freescale/imx8mm.dtsi b/arch/arm64/boot/dts/freescale/imx8mm.dtsi index 76f040e4be5e..38bf41184489 100644 --- a/arch/arm64/boot/dts/freescale/imx8mm.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8mm.dtsi @@ -784,7 +784,7 @@ }; usdhc1: mmc@30b40000 { - compatible = "fsl,imx8mm-usdhc", "fsl,imx7d-usdhc"; + compatible = "fsl,imx8mm-usdhc"; reg = <0x30b40000 0x10000>; interrupts = <GIC_SPI 22 IRQ_TYPE_LEVEL_HIGH>; clocks = <&clk IMX8MM_CLK_IPG_ROOT>, @@ -798,7 +798,7 @@ }; usdhc2: mmc@30b50000 { - compatible = "fsl,imx8mm-usdhc", "fsl,imx7d-usdhc"; + compatible = "fsl,imx8mm-usdhc"; reg = <0x30b50000 0x10000>; interrupts = <GIC_SPI 23 IRQ_TYPE_LEVEL_HIGH>; clocks = <&clk IMX8MM_CLK_IPG_ROOT>, @@ -812,7 +812,7 @@ }; usdhc3: mmc@30b60000 { - compatible = "fsl,imx8mm-usdhc", "fsl,imx7d-usdhc"; + compatible = "fsl,imx8mm-usdhc"; reg = <0x30b60000 0x10000>; interrupts = <GIC_SPI 24 IRQ_TYPE_LEVEL_HIGH>; clocks = <&clk IMX8MM_CLK_IPG_ROOT>, -- 2.17.1
