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 --- Changes in v4: - Moved "rtcclk" clock to board dts file - Specified "rtc_src" clock for rtc node in board dts file - Specified "rtcclk" clock for cmu_hsi node in board dts file - Improved comment for RAM memory node Changes in v3: - Ordered the pinctrl_alive phandle alphabetically (forgot to do so in v2) Changes in v2: - Removed board_id and board_rev properties - Removed BOARD_ID and BOARD_REV constants - Put dtb in alphabetical order in Makefile - Added "color" and "function" properties to LED nodes - Sorted all phandle overrides by phandle name - Removed 'broken-cd' property in eMMC node - Added memory node 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/;
