This short series implements support for the laptop keyboards on the
Apple Silicon Mac laptops. These keyboards are connected to an SPI
bus, so this adds a driver for the SPI controller integrated on the
SoC, as well as the driver for the keyboard itself. This makes it
possible to interact with U-Boot and EFI applications without the
need for an external USB keyboard.
ChangeLog:
v2: - Drop delay after enabling controller
- Check for errors in spi calls
- Add comments
