[v4,0/2] Add Apple SPI keyboard and trackpad driver

Message

Life is hard, and then you die April 7, 2019, 5:03 a.m. UTC

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 fixes a problem during config and is provided for
anybody wanting to compile the driver while it's being reviewed here.
The patch is the latest version that has been submitted for review
at dri-devel; the intent is to get an Ack and permission to merge it
through the input subsystem tree here as part of this patch series.

The second patch contains the new applespi driver.

Changes in v4:
  Applied all feedback from review by Andy Shevchenko and Greg
  Kroah-Hartman, including:
  - minor include path fix
  - moved debug logging to debugfs and tracepoints
  The full set of changes to applespi can be viewed at
  https://github.com/roadrunner2/macbook12-spi-driver/ as individual
  commits 3a6262e..daf60f8 in the upstreaming-review branch.
