[PATCH 2/4] ARM: dts: mstar: Add the Wireless Tag IDO-SBC2D06-V1B-22W

From: Romain Perier
Date: Fri Sep 10 2021 - 15:03:54 EST

The Wireless Tag IDO-SBC2D06-V1B-22W[1] is an SBC powered by SSD202D
with a dual Ethernet and a connector for a 4-inch and 7-inch display.
It embeds a System-On-Module IDO-SOM2D01[2] with an Mstar SSD202 SoC
dual-core Cortex-A7 CPU @ 1.2Ghz , 2D GPU, 128 MB DDR3 (on-chip) and
a 256MB SPI NAND flash. This commit adds basic definition for this
board.
