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.
