We are moving to json-schema format. The fsl.txt has been removed on my for-next branch, so you need to patch fsl.yaml instead. > arch/arm64/boot/dts/freescale/imx8-ca35.dtsi | 61 ++++ > arch/arm64/boot/dts/freescale/imx8qxp.dtsi | 409 ++++++++++++++++++++++++++ > 3 files changed, 474 insertions(+) > create mode 100644 arch/arm64/boot/dts/freescale/imx8-ca35.dtsi > create mode 100644 arch/arm64/boot/dts/freescale/imx8qxp.dtsi > > diff --git a/Documentation/devicetree/bindings/arm/fsl.txt b/Documentation/devicetree/bindings/arm/fsl.txt > index 7fbc424..9b5be3e 100644 > --- a/Documentation/devicetree/bindings/arm/fsl.txt > +++ b/Documentation/devicetree/bindings/arm/fsl.txt > @@ -131,6 +131,10 @@ i.MX7ULP generic board > Required root node properties: > - compatible = "fsl,imx7ulp"; > > +i.MX8QXP generic board > +Required root node properties: > + - compatible = "fsl,imx8qxp"; > + > Freescale Vybrid Platform Device Tree Bindings > ---------------------------------------------- > > diff --git a/arch/arm64/boot/dts/freescale/imx8-ca35.dtsi b/arch/arm64/boot/dts/freescale/imx8-ca35.dtsi > new file mode 100644 > index 0000000..c79e97a > --- /dev/null > +++ b/arch/arm64/boot/dts/freescale/imx8-ca35.dtsi Can you explain it a bit in commit log why we need to have a separate imx8-ca35.dtsi?
