[PATCH] sunxi: H616: Add OrangePi Zero 2W board support

[Jernej Škrabec]

Dne torek, 30. januar 2024 ob 15:16:42 CET je Andre Przywara napisal(a):
> The OrangePi Zero 2W is a tiny development board featuring the Allwinner
> H618 SoC, shipping with up to 4GB of LPDDR4 DRAM, a mini-HDMI connector,
> two USB Type-C sockets and a 16MB SPI NOR flash.
> There is an FPC connector to connect an expansion board, which sports
> two more USB Type-A sockets and a 100MBit Ethernet port. Support for
> the expansion board is not in the DT yet, probably a DT overlay would
> cover this in the future.
> 
> Add a defconfig file selecting the right drivers and DRAM options.
> Since the .dts file was synced from the Linux kernel repo already, we
> just need to add one line to the Makefile to actually build the .dtb.
> 
> The DRAM parameters were derived from the values found in the BSP DRAM
> drivers on the SPI NOR flash.
