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.
