Currently only the UART, LEDs and buttons are supported. Signed-off-by: Alban Bedel --- v2: * Rebased for the new vendor directory structure * Merged the 2 separate patch for SoC dtsi and board DTS in a single one * Fixed the node names to use ePAPR standardized names --- arch/mips/ath79/Kconfig | 5 + arch/mips/boot/dts/Makefile | 1 + arch/mips/boot/dts/qca/Makefile | 9 ++ arch/mips/boot/dts/qca/ar9132.dtsi | 121 +++++++++++++++++++++++ arch/mips/boot/dts/qca/ar9132_tl_wr1043nd_v1.dts | 83 ++++++++++++++++ 5 files changed, 219 insertions(+) create mode 100644 arch/mips/boot/dts/qca/Makefile create mode 100644 arch/mips/boot/dts/qca/ar9132.dtsi create mode 100644 arch/mips/boot/dts/qca/ar9132_tl_wr1043nd_v1.dts diff --git a/arch/mips/ath79/Kconfig b/arch/mips/ath79/Kconfig index 1d38c6a..0df05d0 100644 --- a/arch/mips/ath79/Kconfig +++ b/arch/mips/ath79/Kconfig @@ -79,6 +79,11 @@ choice config DTB_ATH79_NONE bool "None" + + config DTB_TL_WR1043ND_V1 + bool "TL-WR1043ND Version 1" + select BUILTIN_DTB + select SOC_AR913X endchoice endmenu diff --git a/arch/mips/boot/dts/Makefile b/arch/mips/boot/dts/Makefile index 5d95e4b..9975485 100644 --- a/arch/mips/boot/dts/Makefile +++ b/arch/mips/boot/dts/Makefile @@ -3,6 +3,7 @@ dts-dirs += cavium-octeon dts-dirs += lantiq dts-dirs += mti dts-dirs += netlogic +dts-dirs += qca dts-dirs += ralink obj-y := $(addsuffix /, $(dts-dirs)) diff --git a/arch/mips/boot/dts/qca/Makefile b/arch/mips/boot/dts/qca/Makefile new file mode 100644 index 0000000..5f02aa6 --- /dev/null +++ b/arch/mips/boot/dts/qca/Makefile @@ -0,0 +1,9 @@ +dtb-$(CONFIG_DTB_TL_WR1043ND_V1) += ar9132_tl_wr1043nd_v1.dtb + +obj-y += $(patsubst %.dtb, %.dtb.o, $(dtb-y)) + +# Force kbuild to make empty built-in.o if necessary +obj- += dummy.o + +always := $(dtb-y) +clean-files := *.dtb *.dtb.S diff --git a/arch/mips/boot/dts/qca/ar9132.dtsi b/arch/mips/boot/dts/qca/ar9132.dtsi new file mode 100644 index 0000000..c05b65c2 --- /dev/null +++ b/arch/mips/boot/dts/qca/ar9132.dtsi @@ -0,0 +1,121 @@ +/ { + compatible = "qca,ar9132";
