+Subject: [PATCH 2/2] arm64: dts: allwinner: a64: add support for PineTab
+
+PineTab is a 10.1" tablet by Pine64 with Allwinner A64 inside.
+
+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.
