| | * | Input: synaptics - fix resolution for manually provided min/maxBenjamin Tissoires2014-06-08

On the t540p, the resolution is the same regarding X and Y. It is not a problem for xf86-input-synaptics because this driver is only interested in the ratio between X and Y. Unfortunately, xf86-input-cmt uses directly the resolution, and having a null resolution leads to some divide by 0 errors, which are translated by -infinity in the resulting coordinates.

| | * | | Input: synaptics - change min/max quirk table to pnp-id matchingHans de Goede2014-05-26

So switching to pnp-ids give us 2 advantages: 1) It shrinks the quirk list 2) It will lower the new quirk addition frequency, ie the recently added W540 quirk would not have been necessary since it uses the same LEN0034 pnp ids as other models already added before it As an added bonus it actually puts the quirk on the actual psmouse, rather then on the machine, which is technically more correct.

However, Kconfig also allows i8042 to be built as a module while the serio framework is built-in, which causes this link error: drivers/built-in.o: In function `ps2_begin_command': :(.text+0x26b6cc): undefined reference to `i8042_check_port_owner' :(.text+0x26b6d4): undefined reference to `i8042_lock_chip' drivers/built-in.o: In function `ps2_end_command': :(.text+0x26b734): undefined reference to `i8042_check_port_owner' :(.text+0x26b73c): undefined reference to `i8042_unlock_chip' On x86, a specific 'select SERIO_I8042' takes care of it, but not on the other architecture that potentially have a i8042. This patch changes the Kconfig logic to ensure that whenever there is an i8042, it does get used for the serio driver, avoiding the link error above.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible that the controller has an individually switchable power supply. Therefore add support to control a supplying regulator. As this is not always the case, the regulator is requested as optional.

Instead xf86-input-wacom now expects all wacom tablets to be driven by the kernel and to show up as evdev devices. This has caused old serial Wacom tablets to stop working for people who still have such tablets. Julian Squires has written a serio input driver to fix this: https://github.com/tokenrove/wacom-serial-iv This is a cleaned up version of this driver with improved Graphire support (I own an old Graphire myself).

The remove function is no longer required and is completely done away with. Also, the labels in the probe function are removed.

* | | | | Input: add driver for Microchip's CAP1106Daniel Mack2014-07-18

For now, only the capacitive buttons are supported, and no specific settings that can be tweaked for individual channels, except for the device-wide sensitivity gain. The defaults seem to work just fine out of the box, so I'll leave configurable parameters for someone who's in need of them and who can actually measure the impact. All registers are prepared, however. Many of them are just not used for now. The implementation does not make any attempt to be compatible to platform data driven boards, but fully depends on CONFIG_OF. Power management functions are also left for volounteers with the ability to actually test them.

I've asked the original reporter of: https://bugzilla.kernel.org/show_bug.cgi?id=61151 To check that not setting bit 1 does not lead to any adverse effects on his model / BIOS revision, and it does not, so this commit fixes the touchpad not working on these versions by simply never setting bit 1 for laptop models with the no_hw_res quirk.

* | | | Input: elantech - deal with clickpads reporting right button eventsHans de Goede2014-06-08

It looks like Dell has put 2 buttons under the pad, one under each bottom corner, causing this. Since this however still clearly is a real clickpad hardware-wise, we still want to report it as such to userspace, so that things like finger movement in the bottom area can be properly ignored as it should be on clickpads. So deal with this weirdness by simply mapping a right click to a left click on elantech clickpads. As an added advantage this is something which we can simply do on all elantech clickpads, so no need to add special quirks for this weird model.
