--- v4: - No change. v3: - Resort the nodes alphabetically. - Correct the compatible of nodes adt7461a at24,24c512 and pca9547. - Change the name of adt7461a to temp-sensor. v2: - Add root node compatible property. arch/arm64/boot/dts/freescale/Makefile | 1 + arch/arm64/boot/dts/freescale/fsl-ls1043a-qds.dts | 167 ++++++++++++++++++++++ 2 files changed, 168 insertions(+) create mode 100644 arch/arm64/boot/dts/freescale/fsl-ls1043a-qds.dtsdiff --git a/arch/arm64/boot/dts/freescale/Makefile b/arch/arm64/boot/dts/freescale/Makefile index f3c2516..1423fa4 100644 --- a/arch/arm64/boot/dts/freescale/Makefile +++ b/arch/arm64/boot/dts/freescale/Makefile@@ -2,6 +2,7 @@ dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls2080a-qds.dtb dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls2080a-rdb.dtb dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls2080a-simu.dtb dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls1043a-rdb.dtb +dtb-$(CONFIG_ARCH_LAYERSCAPE) += fsl-ls1043a-qds.dtb
The list should maintained alphabetically.
