[PATCH 31/32] riscv: Add Kendryte KD233 board device tree

Damien Le Moal
2020-11-07T08:16:12Z

Add a device tree for the Kendryte KD233 board (K210 test board).
This device tree enables LEDs, some gpios and spi/mmc SD card device.
The WS2812B RGB LED and the 10 position rotary dip switch present on the
board are left undefined.
