* Input: edt-ft5x06 - increase allowed data range for threshold parameterMartin Kepplinger2017-05-221-1/+1
| | | | | | | | | | | | | | | The datasheet and application note does not mention an allowed range for the M09_REGISTER_THRESHOLD parameter. One of our customers needs to set lower values than 20 and they seem to work just fine on EDT EP0xx0M09 with T5x06 touch. So, lacking a known lower limit, we increase the range for thresholds, and set the lower limit to 0. The documentation is updated accordingly.

* Input: edt_ft5x06 - change msleep to usleep_range for small msecsAniroop Mathur2017-01-061-2/+2
| | | | | | | | | | | msleep(1~20) may not do what the caller intends, and will often sleep longer (~20 ms actual sleep for any value given in the 1~20ms range). This is not the desired behaviour for many cases like device resume time, device suspend time, device enable time, retry logic, etc. Thus, change msleep to usleep_range for precise wakeups.

* Input: remove duplicate ft6236 driverHans de Goede2016-08-221-0/+8
| | | | | | | | | | | | | | | | The new(ish) ft6236 simply re-implements the M09 protocol of the (much) older edt-ft5x06.c driver. This commit removes this duplicate driver and adds the i2c ids and dt compatible string to the edt-ft5x06.c driver to keep compatibility. This commit also adds the standard touchscreen properties as optional properties to the edt,ft5x06 binding, these were documented in the focaltech,ft6236 bindingi, but were missing from the edt,ft5x06 doc.

* Input: of_touchscreen - add support for inverted / swapped axesHans de Goede2016-07-151-1/+1
| | | | | | | | | | | | | | | Extend touchscreen_parse_properties() with support for the touchscreen-inverted-x/y and touchscreen-swapped-x-y properties and add touchscreen_set_mt_pos() and touchscreen_report_pos() helper functions for storing coordinates into a input_mt_pos struct, or directly reporting them, taking these properties into account. This commit also modifies the existing callers of touchscreen_parse_properties() to pass in NULL for the new third argument, keeping the existing behavior.

* Input: edt-ft5x06 - fix setting gain, offset, and threshold via device treePhilipp Zabel2016-02-091-6/+12
| | | | | | | | | | | A recent patch broke parsing the gain, offset, and threshold parameters from device tree. Instead of setting the cached values and writing them to the correct registers during probe, it would write the values from DT into the register address variables and never write them to the chip during normal operation.

* Input: edt-ft5x06 - work around FT5506 firmware bugFranklin S Cooper Jr2015-10-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the touchscreen controller ISR, reading the tsc starting from register 0x2 causes the tsc to infrequently update the detected finger's x and y coordinate. The irq pin toggles at a fast rate to indicate touch events are happening. However, the tsc on average updates the touch point's x and y value every ~100 ms which is much slower than the advertised rate of 100+ Hz. This leads to multiple reads within this ~100 ms time window returning the same value. Example: X: 10 , Y: 30 X: 10 , Y: 30 X: 10, Y: 30 .. // After 100 ms X: 300, Y: 300 X: 300, y: 300 .. // After 100 ms X: 1743, Y: 621 X: 1743, Y: 621 For some reason if instead of starting to read at register 0x2 you start reading at register 0x0 this issue isn't seen. This seems like a quirk only seen in the EDT FT5506 so to fix this issue simply adjust the code to start reading from 0x0. Technically this isn't wrong so no regressions should be seen with other touchscreen controllers supported by this driver.

The newer gpio framework takes into account these flags when setting gpio values. Since the values being output were based on voltage and not logic they change to reflect this difference. Also use gpiod_set_value_cansleep since wake and reset pins can be provided by bus based io expanders. Switch from msleep(5) to udelay_range(5000,6000) to avoid check patch warning.

The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.
