Several modern ALPS devices require slight variations on existing driver functions. This patchset provides a way to "mix and match" various components, to avoid excessive code duplication and clutter: - Separating the report format decoding from processing, so that Pinnacle AGx, Rushmore, and Dolphin touchpads can use a common processing function. - Allowing devices with different register layouts to use the same processing functions but disparate init functions. - Providing a way to discover touchpads like Pinnacle AGx and Rushmore, which are identified by a range of EC report values rather than an exact match to a specific E7 report sequence. - Storing the bitmap and pixel constants in the alps_data struct, so they can be updated if the device uses different values (ala Dolphin). V1->V2 changes with respect to Rushmore support: - Fix MT and trackstick report decoding (credit to Emmanual Thome) Baseline: git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git next git pull from: https://github.com/cernekee/linux alps-v2 Tested on: Dell E6410 (Pinnacle AGx) - E7/EC: 73 02 64 / 88 07 9d Dell E6230 (Rushmore without trackstick) - E7/EC: 73 03 0a / 88 08 1d Dell E6430 (Rushmore with trackstick) - E7/EC: 73 03 0a / 88 08 1d Dolphin support is new and completely untested; if nobody reports success we should drop that patch. Also, there are at least two known Dolphin versions, which use different init sequences (at least in the Windows driver).
