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.
