[v5,0/2] Add Apple SPI keyboard and trackpad driver

Message

Life is hard, and then you die April 15, 2019, 8:12 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.

The second patch contains the new applespi driver.

Changes in v5:
  Applied all feedback from review by Andy Shevchenko (applespi) and
  Andrzej Hajda (sil-sii8620), including:
  - (sil_sii8620) use 'if (IS_DEFINED(...))' instead of conditional
    compilation to handle RC_CORE being undefined
  - (applespi) a number of cleanups of leftovers from changes to earlier
    versions
  - (applespi) replace some bool flags with loop-end detection
  - (applespi) improve error reporting in a couple places
  The full set of changes to applespi can be viewed at
  https://github.com/roadrunner2/macbook12-spi-driver/ as individual
  commits daf60f8..36afd70 in the upstreaming-review branch.

Ronald Tschalär (2):
