2016-11-16Input: psmouse - disable automatic probing of BYD touchpadsDmitry Torokhov
BYD automatic protocol detection is extremely unreliable and is often triggers false positives on regular mice, Sentelic touchpads, and other devices. BYD has several documents that have recommended detection sequence, but they conflict with each other and, as far as I can see, still would not produce unique enough output to reliably differentiate BYD from other PS/2 devices. OEMs sourcing BYD devices also do not do us any favors by not supplying any reasonable DMI data and instead leaving turds like "To Be Filled By O.E.M." in place of vendor data, or "System Serial Number" as serial number. On top of that BYD is not truly modern multitouch controller, but rather a single-touch transitional device that only reports absolute coordinates at the beginning of finger contact and then reverts to reporting displacements, and thus not very precise; the only benefit from using BYD mode vs the legacy PS/2 mode is possibility of edge scrolling. Given the above, and the fact that BYD devices are somewhat uncommon, let's disable automatic detection of BYD devices. Users who know they have BYD trackpads or want to experiment can attempt to activate BYD protocol via sysfs: echo -n "byd" > /sys/bus/serio/devices/serio1/drvctl Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=151691 Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=175421 Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=120781 Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=121281 Fixes: 98ee37714493 ("Input: byd - add BYD PS/2 touchpad driver") Cc: stable@vger.kernel.org # 4.6+ Reviewed-by: Pali Rohár <pali.rohar@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2016-11-16Input: bma150 - avoid binding to bma180 if IIO bma180 driver presentHans de Goede
commit ef3714fdbc8d ("Input: bma150 - extend chip detection for bma180"), adds bma180 chip-ids to the input bma150 driver, assuming that they are 100% compatible, but the bma180 is not compatible with the bma150 at all, it has 14 bits resolution instead of 10, and it has quite different control registers too. Treating the bma180 as a bma150 wrt its data registers will just result in throwing away the lowest 4 bits, which is not too bad. But the ctrl registers are a different story. Things happen to just work but supporting that certainly does not make treating the bma180 the same as the bma150 right. Since some setups depend on the evdev interface the bma150 driver offers on top of the bma180, we cannot simply remove the bma180 ids. So this commit only removes the bma180 id when the bma180 iio driver, which does treat the bma180 properly, is enabled.

2016-10-11Input: i8042 - skip selftest on ASUS laptopsMarcos Paulo de Souza
On suspend/resume cycle, selftest is executed to reset i8042 controller. But when this is done in Asus devices, subsequent calls to detect/init functions to elantech driver fails. Skipping selftest fixes this problem. An easier step to reproduce this problem is adding i8042.reset=1 as a kernel parameter. On Asus laptops, it'll make the system to start with the touchpad already stuck, since psmouse_probe forcibly calls the selftest function. This patch was inspired by John Hiesey's change[1], but, since this problem affects a lot of models of Asus, let's avoid running selftests on them.

Another Lifebook machine that needs the same quirk as other similar models to make the driver working. Also let's reorder elantech_dmi_force_crc_enabled list so LIfebook enries are in alphabetical order.

2016-10-04Input: synaptics-rmi4 - fix error handling in I2C transport driverGuenter Roeck
Instantiating the rmi4 I2C transport driver without interrupts assigned (for example using manual i2c instantiation from the command line) caused the driver to fail to load, but it does not clean up its regulator or transport device registrations. Result is a crash at a later time, for example when rebooting the system.
