Subject: [PATCH v5 0/2] Add Apple SPI keyboard and trackpad driver

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 (as well as my clone at

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
  - (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 as individual
  commits daf60f8..36afd70 in the upstreaming-review branch.

Ronald Tschalär (2):
  drm/bridge: sil_sii8620: make remote control optional.
