From mboxrd@z Thu Jan 1 00:00:00 1970 From: heiko@sntech.de (Heiko =?ISO-8859-1?Q?St=FCbner?=) Date: Mon, 29 Jun 2015 14:34:35 +0200 Subject: [PATCH v2 3/4] arm64: dts: add Rockchip rk3368 core dtsi and board dts for the r88 board In-Reply-To: <3333434.ZKWQ6GxgtB@diego> References: <3333434.ZKWQ6GxgtB@diego> Message-ID: <4392776.GZArrLSWTI@diego> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org In terms of peripherals the rk3368 is quite similar to the rk3288, which makes it possible to have a lot basic components working in the first go. More to follow once I tracked down all the tiny differences that still exist in some parts. With these dts files, the R88 board is able to boot from an attached usb device and most likely from its emmc too, if the emmc uses a standard partition table instead of Rockchip's own one - the emmc itself is detected correctly. Signed-off-by: Heiko Stuebner --- This of course needs the dt-binding header from clock series, so a shared branch will be needed. arch/arm64/boot/dts/Makefile | 1 + arch/arm64/boot/dts/rockchip/Makefile | 5 + arch/arm64/boot/dts/rockchip/rk3368-r88.dts | 353 +++++++++++ arch/arm64/boot/dts/rockchip/rk3368.dtsi | 900 ++++++++++++++++++++++++++++ 4 files changed, 1259 insertions(+) create mode 100644 arch/arm64/boot/dts/rockchip/Makefile create mode 100644 arch/arm64/boot/dts/rockchip/rk3368-r88.dts create mode 100644 arch/arm64/boot/dts/rockchip/rk3368.dtsi diff --git a/arch/arm64/boot/dts/Makefile b/arch/arm64/boot/dts/Makefile index ad26a75..6916eec 100644 --- a/arch/arm64/boot/dts/Makefile +++ b/arch/arm64/boot/dts/Makefile @@ -6,6 +6,7 @@ dts-dirs += exynos dts-dirs += freescale dts-dirs += mediatek dts-dirs += qcom +dts-dirs += rockchip dts-dirs += sprd dts-dirs += xilinx diff --git a/arch/arm64/boot/dts/rockchip/Makefile b/arch/arm64/boot/dts/rockchip/Makefile new file mode 100644 index 0000000..601e6a2 --- /dev/null +++ b/arch/arm64/boot/dts/rockchip/Makefile @@ -0,0 +1,5 @@ +dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3368-r88.dtb + +always := $(dtb-y) +subdir-y := $(dts-dirs) +clean-files := *.dtb diff --git a/arch/arm64/boot/dts/rockchip/rk3368-r88.dts b/arch/arm64/boot/dts/rockchip/rk3368-r88.dts new file mode 100644 index 0000000..d0c519b --- /dev/null +++ b/arch/arm64/boot/dts/rockchip/rk3368-r88.dts @@ -0,0 +1,354 @@ +/* + * Copyright (c) 2015 Heiko Stuebner + * + * This file is dual-licensed: you can use it either under the terms + * of the GPL or the X11 license, at your option.
