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 --- arch/arm64/boot/dts/exynos/Makefile | 3 +- .../boot/dts/exynos/exynos850-e850-96.dts | 157 ++++++++++++++++++ 2 files changed, 159 insertions(+), 1 deletion(-) 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..803548ccc537 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 \ - exynosautov9-sadk.dtb + exynosautov9-sadk.dtb \ + exynos850-e850-96.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..fd611906d81c --- /dev/null +++ b/arch/arm64/boot/dts/exynos/exynos850-e850-96.dts @@ -0,0 +1,157 @@ +// 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/; + +#include "exynos850.dtsi" +#include +#include + +#define BOARD_ID 0x0 +#define BOARD_REV 0x2 + +/ { + model = "WinLink E850-96 board"; + compatible = "winlink,e850-96", "samsung,exynos850"; + board_id = ; + board_rev = ; + + chosen { + stdout-path = &serial_0; + }; + + gpio-keys { + compatible = "gpio-keys"; + pinctrl-names = "default"; + pinctrl-0 = <&key_voldown_pins &key_volup_pins>; + + volume-down-key { + label = "Volume Down"; + linux,code = ; + gpios = <&gpa1 0 GPIO_ACTIVE_LOW>; + }; + + volume-up-key { + label = "Volume Up"; + linux,code = ; + gpios = <&gpa0 7 GPIO_ACTIVE_LOW>; + }; + }; + + leds { + compatible = "gpio-leds"; + + /* HEART_BEAT_LED */ + user_led1: led-1 { + label = "yellow:user1"; + gpios = <&gpg2 2 GPIO_ACTIVE_HIGH>; + linux,default-trigger = "heartbeat"; + }; + + /* eMMC_LED */ + user_led2: led-2 { + label = "yellow:user2"; + gpios = <&gpg2 3 GPIO_ACTIVE_HIGH>; + linux,default-trigger = "mmc0"; + }; + + /* SD_LED */ + user_led3: led-3 { + label = "white:user3"; + gpios = <&gpg2 4 GPIO_ACTIVE_HIGH>; + linux,default-trigger = "mmc2"; + }; + + /* WIFI_LED */ + wlan_active_led: led-4 { + label = "yellow:wlan"; + gpios = <&gpg2 6 GPIO_ACTIVE_HIGH>; + linux,default-trigger = "phy0tx"; + default-state = "off"; + }; + + /* BLUETOOTH_LED */ + bt_active_led: led-5 { + label = "blue:bt"; + gpios = <&gpg2 7 GPIO_ACTIVE_HIGH>; + linux,default-trigger = "hci0rx"; + default-state = "off"; + }; + }; +}; + +&oscclk { + clock-frequency = <26000000>; +}; + +&rtcclk { + clock-frequency = <32768>; +}; + +&usi_uart { + samsung,clkreq-on; /* needed for UART mode */ + status = "okay"; +}; + +&serial_0 { + status = "okay"; + pinctrl-names = "default"; + pinctrl-0 = <&uart1_pins>; +}; + +&watchdog_cl0 { + status = "okay"; +}; + +&watchdog_cl1 { + status = "okay"; +}; + +&rtc { + status = "okay"; +}; + +&mmc_0 { + status = "okay"; + mmc-hs200-1_8v; + mmc-hs400-1_8v; + cap-mmc-highspeed; + non-removable; + broken-cd; + mmc-hs400-enhanced-strobe; + card-detect-delay = <200>; + clock-frequency = <800000000>; + bus-width = <8>; + samsung,dw-mshc-ciu-div = <3>; + samsung,dw-mshc-sdr-timing = <0 4>; + samsung,dw-mshc-ddr-timing = <2 4>; + samsung,dw-mshc-hs400-timing = <0 2>; + + pinctrl-names = "default"; + pinctrl-0 = <&sd0_clk_pins &sd0_cmd_pins &sd0_rdqs_pins &sd0_nreset_pins + &sd0_bus1_pins &sd0_bus4_pins &sd0_bus8_pins>; +}; + +&pinctrl_alive { + key_voldown_pins: key-voldown-pins { + samsung,pins = "gpa1-0"; + samsung,pin-function = ; + samsung,pin-pud = ; + samsung,pin-drv = ; + }; + + key_volup_pins: key-volup-pins { + samsung,pins = "gpa0-7"; + samsung,pin-function = ; + samsung,pin-pud = ; + samsung,pin-drv = ; + }; +};
