This patch add support for NXP LS2081ARDB board which has LS2081A SoC. LS2081A SoC is 40-pin derivative of LS2088A SoC So, from functional perspective both are same. Hence,ls2088a SoC dtsi files are included from ls2081ARDB dts Signed-off-by: Priyanka Jain <redacted> --- Changes for v2: Updated subject and NXP copyright based on Leo's comments arch/arm64/boot/dts/freescale/Makefile | 1 + arch/arm64/boot/dts/freescale/fsl-ls2081a-rdb.dts | 139 +++++++++++++++++++++ 2 files changed, 140 insertions(+), 0 deletions(-) create mode 100644 arch/arm64/boot/dts/freescale/fsl-ls2081a-rdb.dtsdiff --git a/arch/arm64/boot/dts/freescale/Makefile b/arch/arm64/boot/dts/freescale/Makefile index 72c4b52..58b80de 100644 --- a/arch/arm64/boot/dts/freescale/Makefile +++ b/arch/arm64/boot/dts/freescale/Makefile@@ -9,6 +9,7 @@ dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls1088a-qds.dtb dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls1088a-rdb.dtb dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls2080a-qds.dtb dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls2080a-rdb.dtb +dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls2081a-rdb.dtb dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls2080a-simu.dtb dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls2088a-qds.dtb dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls2088a-rdb.dtbdiff --git a/arch/arm64/boot/dts/freescale/fsl-ls2081a-rdb.dts b/arch/arm64/boot/dts/freescale/fsl-ls2081a-rdb.dts new file mode 100644 index 0000000..bc1c4f6 --- /dev/null +++ b/arch/arm64/boot/dts/freescale/fsl-ls2081a-rdb.dts@@ -0,0 +1,139 @@ +/* + * Device Tree file for NXP LS2081A RDB Board. + * + * Copyright 2017, NXP
It still doesn't match what Leo's patch does. https://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux.git/commit/?h=imx/dt64&id=827270124c75c7eca8d2e0b41e21fc668e04932e Hint: there is no comma in the middle.
