The board currently comes in two available version: MT8516 SoC and MT8167 SoC. The board provides the following IOs: eMMC, NAND, SD card, USB type-A, Ethernet, Wi-Fi, Bluetooth, Audio (jack out, 2 PDM port, 1 analog in), serial over USB, and an expansion header. Additionally there is a HDMI port, DSI port, and camera port only on the MT8167 version of the board. The board can be powered by battery and/or via a USB Type-C port and is using a PMIC MT6392. The eMMC and NAND are sharing pins and cannot be used together. This commit is adding a basic DTS for the MT8516 flavor. Signed-off-by: Fabien Parent --- V2: * Remove dependency on PMIC MT6392 to make it easier to merge the DTS until the PMIC code is merged. * Rename a bunch of label to make them more straighforward * Use names for keycode instead of magic values * Add chosen for serial port --- arch/arm64/boot/dts/mediatek/Makefile | 1 + .../boot/dts/mediatek/mt8516-pumpkin.dts | 19 ++ .../boot/dts/mediatek/pumpkin-common.dtsi | 188 ++++++++++++++++++ 3 files changed, 208 insertions(+) create mode 100644 arch/arm64/boot/dts/mediatek/mt8516-pumpkin.dts create mode 100644 arch/arm64/boot/dts/mediatek/pumpkin-common.dtsi diff --git a/arch/arm64/boot/dts/mediatek/Makefile b/arch/arm64/boot/dts/mediatek/Makefile index 458bbc422a94..2f8967cb8717 100644 --- a/arch/arm64/boot/dts/mediatek/Makefile +++ b/arch/arm64/boot/dts/mediatek/Makefile @@ -8,3 +8,4 @@ dtb-$(CONFIG_ARCH_MEDIATEK) += mt7622-rfb1.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt7622-bananapi-bpi-r64.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt8173-evb.dtb dtb-$(CONFIG_ARCH_MEDIATEK) += mt8183-evb.dtb +dtb-$(CONFIG_ARCH_MEDIATEK) += mt8516-pumpkin.dtb diff --git a/arch/arm64/boot/dts/mediatek/mt8516-pumpkin.dts b/arch/arm64/boot/dts/mediatek/mt8516-pumpkin.dts new file mode 100644 index 000000000000..d8e283245fbe --- /dev/null +++ b/arch/arm64/boot/dts/mediatek/mt8516-pumpkin.dts @@ -0,0 +1,19 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Copyright (c) 2019 BayLibre, SAS. + * Author: Fabien Parent + */ + +/dts-v1/; + +#include "pumpkin-common.dtsi" + +/ { + model = "Pumpkin MT8516"; + compatible = "pumpkin,mt8516", "mediatek,mt8516"; + + memory@40000000 { + device_type = "memory"; + reg = <0 0x40000000 0 0x40000000>; + }; +}; diff --git a/arch/arm64/boot/dts/mediatek/pumpkin-common.dtsi b/arch/arm64/boot/dts/mediatek/pumpkin-common.dtsi new file mode 100644 index 000000000000..d143cf33cfff --- /dev/null +++ b/arch/arm64/boot/dts/mediatek/pumpkin-common.dtsi @@ -0,0 +1,188 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Copyright (c) 2019 BayLibre, SAS. + * Author: Fabien Parent + */ + +#include +#include + +#include "mt8516.dtsi" + +/ { + aliases { + serial0 = &uart0; + }; + + chosen { + stdout-path = "serial0:921600n8"; + }; + + gpio-keys { + compatible = "gpio-keys"; + input-name = "gpio-keys"; + pinctrl-names = "default"; + pinctrl-0 = <&gpio_keys_pins>; + + volume-up { + gpios = <&pio 42 GPIO_ACTIVE_LOW>; + label = "volume_up"; + linux,code = ; + wakeup-source; + debounce-interval = <15>; + }; + + volume-down { + gpios = <&pio 43 GPIO_ACTIVE_LOW>; + label = "volume_down"; + linux,code = ; + wakeup-source; + debounce-interval = <15>; + }; + }; +}; + +&i2c0 { + clock-div = <2>; + pinctrl-names = "default"; + pinctrl-0 = <&i2c0_pins>; + status = "okay"; + + tca6416: gpio@20 { + compatible = "ti,tca6416"; + reg = <0x20>; + rst-gpio = <&pio 65 GPIO_ACTIVE_HIGH>; + pinctrl-names = "default"; + pinctrl-0 = <&tca6416_pins>; + + gpio-controller; + #gpio-cells = <2>; + + eint20_mux_sel0 { + gpio-hog; + gpios = <0 0>; + input; + line-name = "eint20_mux_sel0"; + }; + + expcon_mux_sel1 { + gpio-hog; + gpios = <1 0>; + input; + line-name = "expcon_mux_sel1"; + }; + + mrg_di_mux_sel2 { + gpio-hog; + gpios = <2 0>; + input; + line-name = "mrg_di_mux_sel2"; + }; + + sd_sdio_mux_sel3 { + gpio-hog; + gpios = <3 0>; + input; + line-name = "sd_sdio_mux_sel3"; + }; + + sd_sdio_mux_ctrl7 { + gpio-hog; + gpios = <7 0>; + output-low; + line-name = "sd_sdio_mux_ctrl7"; + }; + + hw_id0 { + gpio-hog; + gpios = <8 0>; + input; + line-name = "hw_id0"; + }; + + hw_id1 { + gpio-hog; + gpios = <9 0>; + input; + line-name = "hw_id1"; + }; + + hw_id2 { + gpio-hog; + gpios = <10 0>; + input; + line-name = "hw_id2"; + }; + + fg_int_n { + gpio-hog; + gpios = <11 0>; + input; + line-name = "fg_int_n"; + }; + + usba_pwr_en { + gpio-hog; + gpios = <12 0>; + output-high; + line-name = "usba_pwr_en"; + }; + + wifi_3v3_pg { + gpio-hog; + gpios = <13 0>; + input; + line-name = "wifi_3v3_pg"; + }; + + cam_rst { + gpio-hog; + gpios = <14 0>; + output-low; + line-name = "cam_rst"; + }; + + cam_pwdn { + gpio-hog; + gpios = <15 0>; + output-low; + line-name = "cam_pwdn"; + }; + }; +}; + +&uart0 { + status = "okay"; +}; + +&pio { + gpio_keys_pins: gpiokeys{ + pins_gpio { + pinmux = , + ; + bias-pull-up; + input-enable; + }; + }; + + i2c0_pins: i2c0 { + pins_i2c { + pinmux = , + ; + bias-disable; + }; + }; + + tca6416_pins: tca6416 { + pin_gpio_mux_rst_n { + pinmux = ; + output-high; + }; + + pin_gpio_mux_int_n { + pinmux = ; + input-enable; + bias-pull-up; + }; + }; +};
