[Bug 1520874] Re: [MacBook8, 1] keyboard does not work


I believe the bcm5974/bcm5976 driver needs to be extended with support
for accessing the controller over the SPI bus. It's possible the USB
driver is no help and the whole thing needs to be implemented
specifically for this device.

  [MacBook8,1] keyboard does not work

Status in linux package in Ubuntu:

Bug description:
  4.2.0-18-generic and upstream 4.4-rc2 both have no input after grub.
  The touchpad also doesn't work and I would guess they are related
  since both devices show up as children of the GSPI and LPSS
  controllers in OS X.
