Add a device tree for the Ingenic X1000 based YSH & ATIL CU Neo board. Note that this is unselectable via Kconfig until the X1000 SoC is made selectable in a later commit. Signed-off-by: Zhou Yanjie <zhouyanjie@xxxxxxxx> --- Notes: v1->v2: Rebase on top of mips-next, use TCU for system timer and clocksource. v2->v3: No change. arch/mips/boot/dts/ingenic/Makefile | 1 + arch/mips/boot/dts/ingenic/cu1000.dts | 52 ++++++++++++++++++ arch/mips/configs/cu1000_defconfig | 100 ++++++++++++++++++++++++++++++++++ arch/mips/jz4740/Kconfig | 4 ++ 4 files changed, 157 insertions(+) create mode 100644 arch/mips/boot/dts/ingenic/cu1000.dts create mode 100644 arch/mips/configs/cu1000_defconfig diff --git a/arch/mips/boot/dts/ingenic/Makefile b/arch/mips/boot/dts/ingenic/Makefile index 9cc4844..f6db7bb 100644 --- a/arch/mips/boot/dts/ingenic/Makefile +++ b/arch/mips/boot/dts/ingenic/Makefile @@ -2,5 +2,6 @@ dtb-$(CONFIG_JZ4740_QI_LB60) += qi_lb60.dtb dtb-$(CONFIG_JZ4770_GCW0) += gcw0.dtb dtb-$(CONFIG_JZ4780_CI20) += ci20.dtb +dtb-$(CONFIG_X1000_CU1000) += cu1000.dtb obj-$(CONFIG_BUILTIN_DTB) += $(addsuffix .o, $(dtb-y)) diff --git a/arch/mips/boot/dts/ingenic/cu1000.dts b/arch/mips/boot/dts/ingenic/cu1000.dts new file mode 100644 index 00000000..b19872d --- /dev/null +++ b/arch/mips/boot/dts/ingenic/cu1000.dts @@ -0,0 +1,52 @@ +// SPDX-License-Identifier: GPL-2.0 +/dts-v1/;
