From bc6e594104caaa25b3b2b53ea1db3df69623dc61 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Tue, 30 Jan 2024 14:16:42 +0000 Subject: [PATCH] sunxi: H616: Add OrangePi Zero 2W board support 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.
