2014-05-26Input: synaptics - change min/max quirk table to pnp-id matchingHans de Goede1-113/+36
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 Leung1-7/+15
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.

The driver should not immediately read bootloader status when in Application Update Mode. The CHG line will assert when the device has made a state transition and is ready to report a new status via i2c.

* 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 Dyer1-50/+0
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.

This patch adds support for the 0x4004, 0x5000, and 0x5002 sensors found on what should be the Motion R12, Fujitsu Q704, and Fujitsu T904. These tablets use a new report ID (3) for their touch packets and a slightly different HID descriptor format, but are otherwise largely identical in protocol to the "MTTPC" tablets. Note: * The R12 uses its 0x4004 sensor for touch input only. A pen interface is not present in its HID descriptor, though its possible a 0x4004 may be used for pen input by other tablet PCs in the future. * The 0x5002 sensor appears to use a new report ID (8) for its pen packets. The other sensors continue to use the traditional report ID (2).

Note the sun4i-ts controller is capable of detecting a second touch, but when a second touch is present then the accuracy becomes so bad the reported touch location is not useable. The original android driver contains some complicated heuristics using the aprox. distance between the 2 touches to see if the user is making a pinch open / close movement, and then reports emulated multi-touch events around the last touch coordinate (as the dual-touch coordinates are worthless). These kinds of heuristics are just asking for trouble (and don't belong in the kernel). So this driver offers straight forward, reliable single touch functionality only.
