The UART on i.MX 8QXP has its own compatible described in bindings and used in the driver (with its own quirks). Remove additional fsl,imx7ulp-lpuart compatible to fix dtbs_check warnings like: arch/arm64/boot/dts/freescale/imx8qxp-mek.dt.yaml: serial@5a060000: compatible: ['fsl,imx8qxp-lpuart', 'fsl,imx7ulp-lpuart'] is too long From schema: Documentation/devicetree/bindings/serial/fsl-lpuart.yaml arch/arm64/boot/dts/freescale/imx8qxp-mek.dt.yaml: serial@5a060000: compatible: Additional items are not allowed ('fsl,imx7ulp-lpuart' was unexpected) Signed-off-by: Krzysztof Kozlowski <krzk@xxxxxxxxxx> --- arch/arm64/boot/dts/freescale/imx8qxp.dtsi | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/arch/arm64/boot/dts/freescale/imx8qxp.dtsi b/arch/arm64/boot/dts/freescale/imx8qxp.dtsi index e46faac1fe71..61bccb69f09e 100644 --- a/arch/arm64/boot/dts/freescale/imx8qxp.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8qxp.dtsi @@ -257,7 +257,7 @@ }; adma_lpuart0: serial@5a060000 { - compatible = "fsl,imx8qxp-lpuart", "fsl,imx7ulp-lpuart"; + compatible = "fsl,imx8qxp-lpuart"; reg = <0x5a060000 0x1000>; interrupts = <GIC_SPI 225 IRQ_TYPE_LEVEL_HIGH>; clocks = <&adma_lpcg IMX_ADMA_LPCG_UART0_IPG_CLK>, @@ -268,7 +268,7 @@ }; adma_lpuart1: serial@5a070000 { - compatible = "fsl,imx8qxp-lpuart", "fsl,imx7ulp-lpuart"; + compatible = "fsl,imx8qxp-lpuart"; reg = <0x5a070000 0x1000>; interrupts = <GIC_SPI 226 IRQ_TYPE_LEVEL_HIGH>; clocks = <&adma_lpcg IMX_ADMA_LPCG_UART1_IPG_CLK>, @@ -279,7 +279,7 @@ }; adma_lpuart2: serial@5a080000 { - compatible = "fsl,imx8qxp-lpuart", "fsl,imx7ulp-lpuart"; + compatible = "fsl,imx8qxp-lpuart"; reg = <0x5a080000 0x1000>; interrupts = <GIC_SPI 227 IRQ_TYPE_LEVEL_HIGH>; clocks = <&adma_lpcg IMX_ADMA_LPCG_UART2_IPG_CLK>, @@ -290,7 +290,7 @@ }; adma_lpuart3: serial@5a090000 { - compatible = "fsl,imx8qxp-lpuart", "fsl,imx7ulp-lpuart"; + compatible = "fsl,imx8qxp-lpuart"; reg = <0x5a090000 0x1000>; interrupts = <GIC_SPI 228 IRQ_TYPE_LEVEL_HIGH>; clocks = <&adma_lpcg IMX_ADMA_LPCG_UART3_IPG_CLK>, -- 2.17.1
