%description
Device-tree overlays for the Dragon Q8B expansion headers, optional FPC
PCIe connector, and the optional Heatsink 6845B PWM fan. The base Q8B
device tree is shipped by the custom kernel. Enable overlays with
dragon-q8b-overlay.

These overlays target compatible = "radxa,dragon-q8b".
Enable them with dragon-q8b-overlay (enable|disable|list), then reboot.
The kernel-install plugin merges enabled overlays into the Q8B DTB with
fdtoverlay. Do not enable mutually exclusive SPI/ENC28J60 and SPI/spidev
overlays on the same controller.

Heatsink 6845B: dragon-q8b-overlay enable pwm-fan then reboot.
