From 4c09666816df62c1b8ab13410b8d0cc9234c608f Mon Sep 17 00:00:00 2001 From: ashthespy Date: Wed, 15 Jan 2020 14:54:14 +0100 Subject: [PATCH 01/23] arm64: dts: rockchip: add ROCK Pi S DTS support ROCK Pi S is RK3308 based SBC from radxa.com. ROCK Pi S has a, - 256MB/512MB DDR3 RAM - SD, NAND flash (optional on board 1/2/4/8Gb) - 100MB ethernet, PoE (optional) - Onboard 802.11 b/g/n wifi + Bluetooth 4.0 Module - USB2.0 Type-A HOST x1 - USB3.0 Type-C OTG x1 - 26-pin expansion header - USB Type-C DC 5V Power Supply This patch enables - Console - NAND Flash - SD Card Signed-off-by: Akash Gajjar --- Changes for v2 - Use pwm-supply for vdd_core node instead of vi-supply - Add USB2.0 node support Changes for v3 - Use small S on dts file name - Add missing semicolon - Remove USB2.0 node support .../devicetree/bindings/arm/rockchip.yaml | 5 + arch/arm64/boot/dts/rockchip/Makefile | 1 + .../boot/dts/rockchip/rk3308-rock-pi-s.dts | 221 ++++++++++++++++++ 3 files changed, 227 insertions(+) create mode 100644 arch/arm64/boot/dts/rockchip/rk3308-rock-pi-s.dts --- .../boot/dts/rockchip/rk3308-rock-pi-s.dts | 221 ++++++++++++++++++ 2 files changed, 222 insertions(+) create mode 100644 arch/arm64/boot/dts/rockchip/rk3308-rock-pi-s.dts diff --git a/arch/arm64/boot/dts/rockchip/rk3308-rock-pi-s.dts b/arch/arm64/boot/dts/rockchip/rk3308-rock-pi-s.dts new file mode 100644 index 000000000000..4fccae43f008 --- /dev/null +++ b/arch/arm64/boot/dts/rockchip/rk3308-rock-pi-s.dts @@ -0,0 +1,221 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (c) 2019 Akash Gajjar + * Copyright (c) 2019 Jagan Teki + */ + +/dts-v1/;
