Subject: [PATCH v3 0/4] Add Apple SPI keyboard and trackpad driver
Date: Tue, 26 Mar 2019 18:48:03 -0700	[thread overview]
Message-ID: <20190327014807.7472-1-ronald@innovation.ch> (raw)

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.

The second and third patches add a new dev_print_hex_dump() helper as
the dev_xxx() analog of print_hex_dump().

The fourth patch finally contains the new applespi driver.

Changes in v3:
  Applied all feedback from review by Andy Shevchenko, including:
  - move dev_print_hex_dump() to driver core
  - clean up keyboard modifier bits testing/modifying
  - remove DEV() macro
  - minor style issues
  The full set of changes to applespi can be viewed at
  https://github.com/roadrunner2/macbook12-spi-driver/ as individual
  commits f832caa..3a6262e in the upstreaming-review branch.

Ronald Tschalär (4):
  drm/bridge: sil_sii8620: depend on INPUT instead of selecting it.
  lib/hexdump.c: factor out generic hexdump formatting for reuse.
  driver core: add dev_print_hex_dump() logging function.
  Input: add Apple SPI keyboard and trackpad driver.
