It includes the following peripherals: USB: - A microUSB Type-B port connected to the OTG-capable USB PHY of Allwinner A64. The ID pin is connected to a GPIO of the A64 SoC, and the Vbus is connected to the Vbus of AXP803 PMIC. These enables OTG functionality on this port. - A USB Type-A port is connected to the internal hub attached to the non-OTG USB PHY of Allwinner A64. - There are reserved pins for an external keyboard connected to the internal hub. Power: - The microUSB port has its Vbus connected to AXP803, mentioned above. - A DC jack (of a strange size, 2.5mm outer diameter) is connected to the ACIN of AXP803. - A Li-Polymer battery is connected to the battery pins of AXP803. Storage: - An tradition Pine64 eMMC slot is on the board, mounted with an eMMC module by factory. - An external microSD slot is hidden under a protect case. Display: - A MIPI-DSI LCD panel (800x1280) is connected to the DSI port of A64 SoC. - A mini HDMI port. Input: - A touch panel attached to a Goodix GT9271 touch controller. - Volume keys connected to the LRADC of the A64 SoC. Camera: - An OV5640 CMOS camera is at rear, connected to the CSI bus of A64 SoC. - A GC2145 CMOS camera is at front, shares the same CSI bus with OV5640. Audio: - A headphone jack is conencted to the SoC's internal codec. - A speaker connected is to the Line Out port of SoC's internal codec, via an amplifier. Misc: - Debug UART is muxed with the headphone jack, with the switch next to the microSD slot. - A bosch BMA223 accelerometer is connected to the I2C bus of A64 SoC. - Wi-Fi and Bluetooth are available via a RTL8723CS chip, similar to the one in Pinebook. This commit adds a basically usable device tree for it, implementing most of the features mentioned above. HDMI is not supported now because bad LCD-HDMI coexistence situation of mainline A64 display driver, the front camera currently lacks a driver and a facility to share the bus with the rear one, and the accelerometer currently lacks a DT binding. Signed-off-by: Icenowy Zheng --- Changes in v2: - Remove I2C pinmuxes. - Dropped binding-less accelerometer. - Used exponent curve for backlight. arch/arm64/boot/dts/allwinner/Makefile | 1 + .../boot/dts/allwinner/sun50i-a64-pinetab.dts | 460 ++++++++++++++++++ 2 files changed, 461 insertions(+) create mode 100644 arch/arm64/boot/dts/allwinner/sun50i-a64-pinetab.dts diff --git a/arch/arm64/boot/dts/allwinner/Makefile b/arch/arm64/boot/dts/allwinner/Makefile index cf4f78617c3f..6dad63881cd3 100644 --- a/arch/arm64/boot/dts/allwinner/Makefile +++ b/arch/arm64/boot/dts/allwinner/Makefile @@ -9,6 +9,7 @@ dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-orangepi-win.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-pine64-lts.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-pine64-plus.dtb sun50i-a64-pine64.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-pinebook.dtb +dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-pinetab.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-sopine-baseboard.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-a64-teres-i.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h5-bananapi-m2-plus.dtb diff --git a/arch/arm64/boot/dts/allwinner/sun50i-a64-pinetab.dts b/arch/arm64/boot/dts/allwinner/sun50i-a64-pinetab.dts new file mode 100644 index 000000000000..c76c94855f43 --- /dev/null +++ b/arch/arm64/boot/dts/allwinner/sun50i-a64-pinetab.dts @@ -0,0 +1,460 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (C) 2019 Icenowy Zheng + * + */ + +/dts-v1/;
