[PATCH 0/3] arm64: dts: sunxi: Add Liontron H-A133L support

[Andre Przywara]

The Liontron H-A133L is an industrial development board featuring the
Allwinner A133 SoC.
Alongside the usual standard connectors like USB and Ethernet ports,
it contains a number of dedicated JST connectors, to connect external
peripherals.

Add support for that board with the usual patch trinity: vendor prefix,
board name binding, board .dts file.

Please have a look!

Cheers,
Andre

[PATCH 3/3] arm64: dts: allwinner: a100: add Liontron H-A133L board support

[Andre Przywara]

The H-A133L board is an industrial development board made by Liontron.
It contains a number of dedicated JST connectors, to connect external
peripherals. It features:

- Allwinner A133 SoC (4 * Arm Cortex-A53 cores at up to 1.6 GHz)
- 1 GiB, 2 GiB or 4 GiB of LPDDR4 DRAM
- between 16 and 128 GiB eMMC flash
- AXP707 PMIC (compatible to AXP803)
- 100 Mbit/s RJ45 Ethernet socket, using an JLSemi JL1101 PHY
- XR829 WIFI+Bluetooth chip
- 2 * USB 2.0 USB-A ports, plus three sets of USB pins on connectors
  (connected via a USB hub connected to USB1 on the SoC)
- microSD card slot
- 3.5mm A/V port
- 12V power supply
- connectors for an LVDS or MIPI-DSI panel

Add the devicetree describing the board's peripherals and their
connections.

Despite being a devboard, the manufacturer does not publish a schematic
(I asked), so the PMIC rail assignments were bases on BSP dumps,
educated guesses and some experimentation. Dropping the always-on
property from any of the rails carrying it will make the board hang as
soon as the kernel turns off unused regulators.
