Add support for the Forlinx FETA40i-C SoM and OKA40i-C devboard[1] based on it. The DT is split into a .dtsi, which (hopefully) corresponds to the functions of the SoM itself, and a .dts for the devboard. [1]:https://linux-sunxi.org/Forlinx_OKA40i-C Signed-off-by: Ivan Uvarov <i.uvarov@xxxxxxxxxxxxxxxxxx> --- draft2 -> v1: * fix indentation from spaces to tabs; * remove commented properties and other extraneous comments; * enable uarts 2,4,5&7 and alias uart3; * update the user-LED bindings; * remove mmc1 & add mmc3 binding; * bring together the max/min microvolts on three regulators; * The 2.5v in ALDO2 came from U-Boot, where apparently this is the KConfig default for this regulator. The correct voltage is 1.8v. * remove extraneous `always-on`s from regulators dldo1 and eldo2/3; * remove reg_dldo3 node entirely. arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/sun8i-r40-feta40i.dtsi | 68 +++++++ arch/arm/boot/dts/sun8i-r40-oka40i-c.dts | 245 +++++++++++++++++++++++ arch/arm/boot/dts/sun8i-r40.dtsi | 35 ++++ 4 files changed, 349 insertions(+) create mode 100644 arch/arm/boot/dts/sun8i-r40-feta40i.dtsi create mode 100644 arch/arm/boot/dts/sun8i-r40-oka40i-c.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 8e5d4ab4e7..88aae9de95 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -1222,6 +1222,7 @@ dtb-$(CONFIG_MACH_SUN8I) += \ sun8i-r16-nintendo-super-nes-classic.dtb \ sun8i-r16-parrot.dtb \ sun8i-r40-bananapi-m2-ultra.dtb \ + sun8i-r40-oka40i-c.dtb \ sun8i-s3-elimo-initium.dtb \ sun8i-s3-lichee-zero-plus.dtb \ sun8i-s3-pinecube.dtb \ diff --git a/arch/arm/boot/dts/sun8i-r40-feta40i.dtsi b/arch/arm/boot/dts/sun8i-r40-feta40i.dtsi new file mode 100644 index 0000000000..4764661849 --- /dev/null +++ b/arch/arm/boot/dts/sun8i-r40-feta40i.dtsi @@ -0,0 +1,68 @@ +// SPDX-License-Identifier: GPL-2.0+ OR MIT +// Copyright (C) 2021 Ivan Uvarov <i.uvarov@xxxxxxxxxxxxxxxxxx> +// Based on the sun8i-r40-bananapi-m2-ultra.dts, which is: +// Copyright (C) 2017 Chen-Yu Tsai <wens@xxxxxxxx> +// Copyright (C) 2017 Icenowy Zheng <icenowy@xxxxxxx> + + +#include "sun8i-r40.dtsi" + + +&i2c0 { + status = "okay";
