Add the device tree for LCKFB Taishan Pi 3M, a board based on the
Rockchip RK3576 SoC.
The board schematics are available at:
https://oshwhub.com/li-chuang-kai-fa-ban/project_gzzvrwqn
Describe the RK806 supplies, eMMC, recovery key, RTC, SD card,
Gigabit Ethernet, USB Type-A hosts, source-only USB Type-C host,
mSATA, HDMI video and audio, AP6256 Wi-Fi and Bluetooth, status LED,
thermal sensors, and debug UART.
The MAE0621A PHY CLKOUT supplies the GMAC reference-clock input, so
request its validated 125 MHz setting.
The following interfaces were tested on the hardware: eMMC, RTC
register access, recovery key, SD card, 1GbE, USB 2.0 Type-A storage,
USB 3.0 Type-A 5 Gbit/s enumeration and 64 MiB storage I/O, USB-C
source/host enumeration in both orientations, mSATA, HDMI video and
audio, AP6256 2.4/5 GHz Wi-Fi scan, WPA2 association, ping and
bidirectional throughput, Bluetooth firmware load and HCI bring-up,
and UART0. Bluetooth active discovery was additionally exercised
during bring-up.
