Board is based on Exynos 5420, and has similar hardware to Chagall WiFi, but with a smaller battery, smaller screen and another touchscreen controller. The device tree added here contains support for: - UART access through a micro-usb cable with 619 kOhm between ID & GND - Accessing the internal eMMC storage - Accessing an external SD card - USB, after configuration it is possible to ssh into the device through a usb cable Signed-off-by: Henrik Grimler --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/exynos5420-klimt-wifi.dts | 75 +++++++++++++++++++++ 2 files changed, 76 insertions(+) create mode 100644 arch/arm/boot/dts/exynos5420-klimt-wifi.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 28fbfda94cb9..21c4a3ad068a 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -222,6 +222,7 @@ dtb-$(CONFIG_ARCH_EXYNOS5) += \ exynos5420-peach-pit.dtb \ exynos5420-smdk5420.dtb \ exynos5420-chagall-wifi.dtb \ + exynos5420-klimt-wifi.dtb \ exynos5422-odroidhc1.dtb \ exynos5422-odroidxu3.dtb \ exynos5422-odroidxu3-lite.dtb \ diff --git a/arch/arm/boot/dts/exynos5420-klimt-wifi.dts b/arch/arm/boot/dts/exynos5420-klimt-wifi.dts new file mode 100644 index 000000000000..011787b1bbf0 --- /dev/null +++ b/arch/arm/boot/dts/exynos5420-klimt-wifi.dts @@ -0,0 +1,75 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Samsung's Exynos5420 Klimt WiFi board device tree source + * + * Copyright (c) 2012-2013 Samsung Electronics Co., Ltd. + * http://www.samsung.com + * Copyright (c) 2022 Henrik Grimler + */ + +/dts-v1/; +#include "exynos5420-galaxy-tab-common.dtsi" + +/ { + model = "Samsung Klimt WiFi based on Exynos5420"; + compatible = "samsung,klimt-wifi", "samsung,exynos5420", \ + "samsung,exynos5"; +}; + +&ldo15_reg { + /* Unused */ + regulator-name = "VDD_LDO15"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; +}; + +&ldo17_reg { + regulator-name = "VDD_VCI_3V0"; + regulator-min-microvolt = <3000000>; + regulator-max-microvolt = <3000000>; + + regulator-state-mem { + regulator-off-in-suspend; + }; +}; + +&ldo28_reg { + regulator-name = "VDD3_1V8"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + + regulator-state-mem { + regulator-off-in-suspend; + }; +}; + +&ldo29_reg { + regulator-name = "VDDR_1V6"; + regulator-min-microvolt = <1600000>; + regulator-max-microvolt = <1600000>; + + regulator-state-mem { + regulator-off-in-suspend; + }; +}; + +&ldo31_reg { + /* Unused */ + regulator-name = "VDD_LDO31"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; +}; + +&ldo32_reg { + regulator-name = "VDD_TSP_1V8"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + + regulator-state-mem { + regulator-off-in-suspend; + }; +}; + +&mmc_2 { + sd-uhs-sdr104; +};
