[PATCH v2 0/2] Add Apple SPI keyboard and trackpad driver

[Ronald TschalÃr]

This changeset adds a driver for the SPI keyboard and trackpad on recent
MacBook's and MacBook Pro's. The driver has seen a fair amount of use
over the last 2 years (basically anybody running linux on these
machines), with only relatively small changes in the last year or so.
For those interested, the driver development has been hosted at
https://github.com/cb22/macbook12-spi-driver/ (as well as my clone at
https://github.com/roadrunner2/macbook12-spi-driver/).

The first patch is just a placeholder for now and is provided in case
somebody wants to compile the driver while it's being reviewed here; the
real patch has been submitted to dri-devel and is being discussed there,
with the intent/hope that I can get an Ack and permission to merge it
through the input subsystem tree here as part of this patch series.

Changes in v2:
  Applied all feedback from review by Andy Shevchenko, including:
  - reworked logging to use dev_xxx() everywhere
  - split 16-bit model_id field into 2 8-bit fields
  - factored out several pieces of code into separate functions
  - many code style improvements and cleanups
  - Kconfig dependency fixes
  The full set of changes (except for the Kconfig) can be viewed at
  https://github.com/roadrunner2/macbook12-spi-driver/ as individual
  commits a651bb9..f832caa in the upstreaming-review branch.
