I hope so, but I'm not the subsystems maintainer, so I don't know.

Title:
  MacBook Air 6,2 (mid2013) Touchpad is Non-Functional

Status in The Linux Kernel:
  Unknown
Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The MacBook Air 6,2 models (11 and 13 inch) touchpad is basically
  broken; it does not function as a multitouch device, rather it
  provides the functionality of a basic single-click mouse.  All
  multitouch capabilities are broken (right-click, scroll, gestures,
  etc.).

  I would expect that the touchpad would function as a normal fully-
  functional touchpad, instead the touchpad functionality is limited to
  mouse-movement and left-clicking.

  The 2013 MacBook Air laptops have a new hardware touchpad device
  (05ac:0291) which is not compatible with the 'bcm5974' multitouch
  driver.  As a result, the generic 'usbhid' is being associated with
  the device (evident in /sys/bus/usb/drivers/usbhid/), which has the
  effect of the touchpad being registered as a 'Pointer' rather than a
  'Touchpad' in X.  As a result, it is assigned the generic evdev X
  mouse driver rather than the synaptics X driver.

  I have been able to 'force' the touchpad to be associated with the
  'bcm5974' kernel driver (via sysfs), however, the driver fails to
  communicate with the hardware and no mouse functionality is available.
  In this case the bcm5974 reports 'could not read from device' in
  dmesg.
