System	Support
ADC driver	:heavy_check_mark:
Audio	:heavy_check_mark: (via PWM software or hardware, as the MCU does not support DAC)
Backlight	:heavy_check_mark: (via PWM, timer and software)
I2C driver	:heavy_check_mark:
SPI driver	:heavy_check_mark:
WS2812 driver	:heavy_check_mark: (via bit-bang, SPI or PWM driver)
External EEPROMs	:heavy_multiplication_x:
EEPROM emulation	:heavy_check_mark:
Serial driver	:heavy_check_mark: (Full-duplex only (1))
UART driver	:exclamation: (Untested in QMK, but verified in ChibiOS)
SIO driver	:exclamation: (Untested in QMK, but verified in ChibiOS)
OTG HS using DMA	:exclamation: (Untested in QMK, but verified in ChibiOS)

Notes:

• (1): Half-duplex mode for the serial driver has not been tested.
• :heavy_multiplication_x: is not been tested due to lack of available hardware.

Getting a lot of these:

lib/chibios/os/hal/ports/AT32/AT32F402_405/platform.mk: No such file or directory

These should be chibios-contrib, I think. Not sure why it's picking that.

Wait, did ChibiOS-Contrib submodule still not updated yet?
