Waiting on proper extcon support for USB3 over TypeC. - Depends on XHCI/DWC3 fixes for ARM64 that still haven't landed * Backlight Not working: * CPUFreq -- relies on special OVP support for our PWM regulator circuits * EC / extcon support -- and with it, USB3/TypeC/DP * DRM -- won't even build on ARM64, so all display, eDP, etc. is not enabled Not tested: * Audio Signed-off-by: Brian Norris Tested-by: Enric Balletbo i Serra --- v2 -> v3: * reference {pmu-,}io-domain nodes from main rk3399.dtsi * drop some now-superfluous comments * use new proposed '#include ' DTSI include path (symlink) v1 -> v2: * drop deprecated da7219 'dlg,ldo-lvl' property * update copyrights * adjust GPLL to 600 MHz * drop PCIe link speed overrides (they're in rk3399.dtsi now) * fix spi1 leakage with "sleep" state pinctrl * drop unneeded "google,cros-ec-spi-pre-delay" --- arch/arm64/boot/dts/rockchip/Makefile | 1 + arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts | 312 +++++++ arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi | 988 ++++++++++++++++++++++ 3 files changed, 1301 insertions(+) create mode 100644 arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts create mode 100644 arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi diff --git a/arch/arm64/boot/dts/rockchip/Makefile b/arch/arm64/boot/dts/rockchip/Makefile index 3a862894ea44..b82f7b61ab6f 100644 --- a/arch/arm64/boot/dts/rockchip/Makefile +++ b/arch/arm64/boot/dts/rockchip/Makefile @@ -4,6 +4,7 @@ dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3368-orion-r68-meta.dtb dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3368-px5-evb.dtb dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3368-r88.dtb dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-evb.dtb +dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-gru-kevin.dtb always := $(dtb-y) subdir-y := $(dts-dirs) diff --git a/arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts b/arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts new file mode 100644 index 000000000000..2f720cf2fd07 --- /dev/null +++ b/arch/arm64/boot/dts/rockchip/rk3399-gru-kevin.dts @@ -0,0 +1,312 @@ +/* + * Google Gru-Kevin Rev 6+ board device tree source + * + * Copyright 2016-2017 Google, Inc + * + * This file is dual-licensed: you can use it either under the terms + * of the GPL or the X11 license, at your option.
