* Input: pixcir_i2c_ts - fix receive errorFrodo Lai2015-07-21
| | | | | | | | | | | | | | | | commit 469d7d22cea146e40efe8c330e5164b4d8f13934 upstream. The i2c_master_recv() uses readsize to receive data from i2c but compares to size of rdbuf which is always 27. This would cause problem when the max_fingers is not 5. Change the comparison value to readsize instead.

| * Input: smtpe-ts - wait 50mS until polling for pen-upMarek Vasut2015-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wait a little bit longer, 50mS instead of 20mS, until the driver starts polling for pen-up. The problematic behavior before this patch is applied is as follows. The behavior was observed on the STMPE610QTR controller. Upon a physical pen-down event, the touchscreen reports one set of x-y-p coordinates and a pen-down event. After that, the pen-up polling is triggered and since the controller is not ready yet, the polling mistakenly detects a pen-up event while the physical state is still such that the pen is down on the touch surface. The pen-up handling flushes the controller FIFO, so after that, all the samples in the controller are discarded. The controller becomes ready shortly after this bogus pen-up handling and does generate again a pen-down interrupt. This time, the controller contains x-y-p samples which all read as zero. Since pressure value is zero, this set of samples is effectively ignored by userland. In the end, the driver just bounces between pen-down and bogus pen-up handling, generating no useful results. Fix this by giving the controller a bit more time before polling it for pen-up.

This is a problem if you have two Elan touchscreens using the same driver. If both touchscreens have different firmwares, you would need to move the files around in your filesystem when you're updating them so that they don't get updated with the other's FW. If you have a read-only filesystem then this is impossible, even. This patch changes the elants_i2c driver to automatically append the four-hex-digit hw_version of the device onto the name of the FW file it's requesting for update. Since different touchscreens should have a different hw_version's this means the user needs to append the hw version of the touchscreen he or she intends to update onto the end of the firmware filename and then the driver will do the rest. The firmware filenames it looks for now are of the form: elants_i2c_${HW_VERSION}.bin eg: elants_i2c_2a44.bin Signed-off-by: Charlie Mooney <charliemooney@chromium.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

* Input: ti_am335x_tsc - remove udelay in interrupt handlerBrad Griffis2015-02-03
| | | | | | | | | | | | | | | | | | | | | | | TSC interrupt handler had udelay to avoid reporting of false pen-up interrupt to user space. This patch implements workaround suggesting in Advisory 1.0.31 of silicon errata for am335x, thus eliminating udelay and touchscreen lag. This also improves performance of touchscreen and eliminates sudden jump of cursor at touch release. IDLECONFIG and CHARGECONFIG registers are to be configured with same values in order to eliminate false pen-up events. This workaround may result in false pen-down to be detected, hence considerable charge step delay needs to be added. The charge delay is set to 0xB000 (in terms of ADC clock cycles) by default. TSC steps are disabled at the end of every sampling cycle and EOS bit is set. Once the EOS bit is set, the TSC steps need to be re-enabled to begin next sampling cycle.

* Input: ti_am335x_tsc - interchange touchscreen and ADC stepsBrad Griffis2015-02-03
| | | | | | | | | | | | | | | | | This patch makes the initial changes required to workaround TSC-false pen-up interrupts. It is required to implement these changes in order to remove udelay in the TSC interrupt handler and false pen-up events. The charge step is to be executed immediately after sampling X+. Hence TSC is made to use higher numbered steps (steps 5 to 16 for 5 co-ordinate readouts, 4 wire TSC configuration) and ADC to use lower ones. Further X co-ordinate readouts must be the last to be sampled, thus co-ordinates are sampled in the order Y-Z-X.

* Input: MT - add support for balanced slot assignmentHenrik Rydberg2015-02-01
| | | | | | | | | | | | | | | | | Some devices are not fast enough to differentiate between a fast-moving contact and a new contact. This problem cannot be fully resolved because information is truly missing, but it is possible to safe-guard against obvious mistakes by restricting movement with a maximum displacement. The new problem formulation for dmax > 0 cannot benefit from the speedup for positive definite matrices, but since the convergence is faster, the result is about the same. For a handful of contacts, the latency difference is truly negligible.

Add DT thermal zone support so we can use it with cpufreq for thermal throttling. This also adds a comment stating that we do not know the actual formula for calculating the temperature.
