Mon Feb 13 17:11:37 CET 2023
Add Radxa ROCK 3 Model A support. sync rk3308-rock-pi-s.dts from
Linux 6.2.0-rc7.
ROCK Pi S is RK3308 based SBC from radxa.com. ROCK Pi S has a,
- 256MB/512MB DDR3 RAM
- SD, NAND flash (optional on board 1/2/4/8Gb)
- 100MB ethernet, PoE (optional)
- Onboard 802.11 b/g/n wifi + Bluetooth 4.0 Module
- USB2.0 Type-A HOST x1
- USB3.0 Type-C OTG x1
- 26-pin expansion header
- USB Type-C DC 5V Power Supply
Linux commit commit for the same,
