2014-06-07Input: synaptics - fix resolution for manually provided min/maxBenjamin Tissoires
commit 421e08c41fda fixed the reported min/max for the X and Y axis, but unfortunately, it broke the resolution of those same axis. 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.

2014-06-07Input: elantech - don't set bit 1 of reg_10 when the no_hw_res quirk is setHans de Goede
The touchpad on the GIGABYTE U2442 not only stops communicating when we try to set bit 3 (enable real hardware resolution) of reg_10, but on some BIOS versions also when we set bit 1 (enable two finger mode auto correct). 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.

2014-06-07Input: elantech - deal with clickpads reporting right button eventsHans de Goede
At least the Dell Vostro 5470 elantech *clickpad* reports right button clicks when clicked in the right bottom area: https://bugzilla.redhat.com/show_bug.cgi?id=1103528 This is different from how (elantech) clickpads normally operate, normally no matter where the user clicks on the pad the pad always reports a left button event, since there is only 1 hardware button beneath the path. 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.

In no particular order: - Multi-cluster power management for Samsung Exynos, adding support for big.LITTLE CPU switching on EXYNOS5 - SMP support for Marvell Armada 375 and 38x - SMP rework on Allwinner A31 - Xilinx Zynq support for SOC_BUS, big endian - Marvell orion5x platform cleanup, modernizing the implementation and moving to DT. - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so that their platform can be enabled in the same kernel binary as most of the other v7 platforms in the tree. \o/ The work isn't quite complete, there's some driver fixes still needed, but the basics now work.

2014-05-26Input: synaptics - change min/max quirk table to pnp-id matchingHans de Goede
Most of the affected models share pnp-ids for the touchpad. 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.

2014-05-18Input: atmel_mxt_ts - wait for CHG after bootloader resetsBenson Leung
Rather than msleep for MXT_RESET_TIME and MXT_FWRESET_TIME during the transition to bootloader mode and the transition back from app, wait for the CHG assert to indicate that the transition is done. This change replaces the msleep with a wait for completion that the mxt_interrupt handler signals. Also add CHG poll after last firmware frame - some bootloader versions will assert the interrupt line after the final frame, in testing this meant that the driver attempts to read the info block too early whilst the chip is still resetting. This improves firmware update time as we no longer wait longer than necessary for each reset.

2014-05-18Input: atmel_mxt_ts - improve T19 GPIO keys handlingNick Dyer
* The mapping of the GPIO numbers into the T19 status byte varies between different maXTouch chips. Some have up to 7 GPIOs. Allowing a keycode array of up to 8 items is simpler and more generic. So replace #define with configurable number of keys which also allows the removal of is_tp. * Rename platform data parameters to include "t19" to prevent confusion with T15 key array. * Probe aborts early on when pdata is NULL, so no need to check. * Move "int i" to beginning of function (mixed declarations and code) * Use API calls rather than __set_bit() * Remove unused dev variable.

2014-05-18Input: atmel_mxt_ts - remove unnecessary platform dataNick Dyer
It is not necessary to download these values to the maXTouch chip on every probe, since they are stored in NVRAM. It makes life difficult when tuning the device to keep them in sync with the config array/file, and requires a new kernel build for minor tweaks. These parameters only represent a tiny subset of the available configuration options, tracking all of these options in platform data would be a endless task. In addition, different versions of maXTouch chips may have these values in different places or may not even have them at all. Having these values also makes life more complex for device tree and other platforms where having to define a static configuration isn't helpful.
