This patch adds the support for APM Merlin board. The Merlin board is based on the APM X-Gene Shadowcat SoC. This DTS enables PMU, SATA and Serial.
Signed-off-by: Feng Kan <[email protected]> --- V3 Change: - Add PCIe - Add merline to makefile in dts/apm directory V2 Change: - Add dma-range definition V1 Change: - add memreserve for spintable. - remove clkfreq attribute - update spin location, although it is done by bootloader. - remove msi reg entry - add chosen for stdout path arch/arm64/boot/dts/apm/Makefile | 1 + arch/arm64/boot/dts/apm/apm-merlin.dts | 42 ++++++ arch/arm64/boot/dts/apm/apm-shadowcat.dtsi | 216 +++++++++++++++++++++++++++++ 3 files changed, 259 insertions(+) create mode 100644 arch/arm64/boot/dts/apm/apm-merlin.dts create mode 100644 arch/arm64/boot/dts/apm/apm-shadowcat.dtsi diff --git a/arch/arm64/boot/dts/apm/Makefile b/arch/arm64/boot/dts/apm/Makefile index a2afabb..c75f17a 100644 --- a/arch/arm64/boot/dts/apm/Makefile +++ b/arch/arm64/boot/dts/apm/Makefile @@ -1,4 +1,5 @@ dtb-$(CONFIG_ARCH_XGENE) += apm-mustang.dtb +dtb-$(CONFIG_ARCH_XGENE) += apm-merlin.dtb always := $(dtb-y) subdir-y := $(dts-dirs) diff --git a/arch/arm64/boot/dts/apm/apm-merlin.dts b/arch/arm64/boot/dts/apm/apm-merlin.dts new file mode 100644 index 0000000..2480baf --- /dev/null +++ b/arch/arm64/boot/dts/apm/apm-merlin.dts @@ -0,0 +1,42 @@ +/* + * dts file for AppliedMicro (APM) Merlin Board + * + * Copyright (C) 2015, Applied Micro Circuits Corporation + * + * This program is free software;
