Subject: [PATCH 0/5] arm64: allwinner: t527: Add OrangePi 4A board

From: Chen-Yu Tsai <wens@...e.org>

Hi everyone,

This series adds support for the OrangePi 4A board. This is a Raspberry
Pi model B form factor development board based on the Allwinner T527
SoC.

The board has the following features:
- Allwinner T527 SoC
- AXP717B + AXP323 PMICs
- Up to 4GB LPDDR4 DRAM
- micro SD slot
- optional eMMC module
- M.2 slot for PCIe 2.0 x1
- 16 MB SPI-NOR flash
- 4x USB 2.0 type-A ports (one can be used in gadget mode)
- 1x Gigabit ethernet w/ Motorcomm PHY (through yet to be supported GMAC200)
- 3.5mm audio jack via internal audio codec
- HDMI 2.0 output
- eDP, MIPI CSI (2-lane and 4-lane) and MIPI DSI (4-lane) connectors
- USB type-C port purely for power
- AP6256 (Broadcom BCM4345) WiFi 5.0 + BT 5.0
- unsoldered headers for ADC and an additional USB 2.0 host port
- 40-pin GPIO header

Patch 1 adds a new entry to the list of board compatibles.

Patch 2 and 3 are minor cleanups.

Patch 4 adds pins for UART1, which is used for BT on the board.

Patch 5 adds a dts file for the new board.


Please take a look. I will take all the patches through the sunxi tree.


Thanks
ChenYu
