From 7638d3c945beb6c781acf5dd0a78e04c76f1c32f Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 11 Jan 2022 18:48:01 +0100 Subject: [PATCH 1/8] arm64: dts: exynos: Align MAX77843 nodes with dtschema on TM2 The newly introduced dtschema for MAX77843 MUIC require the children to have proper naming and a port@0 property. This should not have actual impact on MFD children driver binding, because the max77843 MFD driver uses compatibles. The port@0 is disabled to avoid any impact.

This patch adds initial SoC support. It's not comprehensive yet, some more devices will be added later. Right now only crucial system components and most needed platform devices are defined. Crucial features (needed to boot Linux up to shell with serial console): * Octa cores (Cortex-A55), supporting PSCI v1.0 * ARM architected timer (armv8-timer) * Interrupt controller (GIC-400) * Pinctrl nodes for GPIO * Serial node Basic platform features: * Clock controller CMUs * OSCCLK clock * MCT timer * ARM PMU (Performance Monitor Unit) * Chip-id * RTC * Reset * Watchdog timers * eMMC * I2C * HSI2C * USI All those features are tested on E850-96 board with minimal BusyBox rootfs.

It incorporates Samsung Exynos850 SoC, and is compatible with 96boards mezzanine boards [1], as it follows 96boards standards. This patch adds minimal support for E850-96 board. Next features are enabled in board dts file and verified with minimal BusyBox rootfs: * User buttons * LEDs * Serial console * Watchdog timers * RTC * eMMC [1] https://www.96boards.org/products/mezzanine/ Signed-off-by: Sam Protsenko Link: https://lore.kernel.org/r/20220131130849.2667-3-semen.protsenko@linaro.org Signed-off-by: Krzysztof Kozlowski --- arch/arm64/boot/dts/exynos/Makefile | 1 + .../boot/dts/exynos/exynos850-e850-96.dts | 195 ++++++++++++++++++ 2 files changed, 196 insertions(+) create mode 100644 arch/arm64/boot/dts/exynos/exynos850-e850-96.dts diff --git a/arch/arm64/boot/dts/exynos/Makefile b/arch/arm64/boot/dts/exynos/Makefile index b41e86df0a84..be9df8e85c59 100644 --- a/arch/arm64/boot/dts/exynos/Makefile +++ b/arch/arm64/boot/dts/exynos/Makefile @@ -3,4 +3,5 @@ dtb-$(CONFIG_ARCH_EXYNOS) += \ exynos5433-tm2.dtb \ exynos5433-tm2e.dtb \ exynos7-espresso.dtb \ + exynos850-e850-96.dtb \ exynosautov9-sadk.dtb diff --git a/arch/arm64/boot/dts/exynos/exynos850-e850-96.dts b/arch/arm64/boot/dts/exynos/exynos850-e850-96.dts new file mode 100644 index 000000000000..7b5a61d22cc5 --- /dev/null +++ b/arch/arm64/boot/dts/exynos/exynos850-e850-96.dts @@ -0,0 +1,195 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * WinLink E850-96 board device tree source + * + * Copyright (C) 2018 Samsung Electronics Co., Ltd. + * Copyright (C) 2021 Linaro Ltd. + * + * Device tree source file for WinLink's E850-96 board which is based on + * Samsung Exynos850 SoC. + */ + +/dts-v1/;
