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 is just a placeholder for now and is provided in case somebody wants to compile the driver while it's being reviewed here; the real patch has been submitted to dri-devel and is being discussed there, with the intent/hope that I can get an Ack and permission to merge it through the input subsystem tree here as part of this patch series. Changes in v2: Applied all feedback from review by Andy Shevchenko, including: - reworked logging to use dev_xxx() everywhere - split 16-bit model_id field into 2 8-bit fields - factored out several pieces of code into separate functions - many code style improvements and cleanups - Kconfig dependency fixes The full set of changes (except for the Kconfig) can be viewed at https://github.com/roadrunner2/macbook12-spi-driver/ as individual commits a651bb9..f832caa in the upstreaming-review branch. Ronald Tschalär (2): drm/bridge: sil_sii8620: depend on INPUT instead of selecting it.
