* Input: edt-ft5x06 - use pm core to enable/disable the wake irqMarco Felsch2020-01-101-24/+0
| | | | | | | | | We do not have to handle the wake-irq within the driver because the pm core can handle this for us. The only use case for the suspend/resume callbacks was to handle the wake-irq so we can remove the callbacks.

* Input: edt-ft5x06 - make wakeup-source switchableMarco Felsch2020-01-101-1/+0
| | | | | | | | | | | | | | | | | | Since day one the touch controller acts as wakeup-source. This seems to be wrong since the device supports deep-sleep mechanism [1] which requires a reset to leave it. Also some designs won't use the touchscreen as wakeup-source. According discussion [2] we decided to break backward compatibility and go the common way by using the 'wakeup-source' device-property.

| | | | | | | | | | | | | | | | | reg_addr->reg_report_rate is supposed to exist in M06, not M09. The driver is written to skip avoids access to non-existing registers when the register address is NO_REGISTER (0xff). But reg_addr->reg_report_rate is initialized to 0x00 by devm_kzalloc() (in edt_ft5x06_ts_probe()) and not changed thereafter. So the checks do not work and an access to register 0x00 is done. Fix by setting reg_addr->reg_report_rate to NO_REGISTER. Also fix the only place where reg_report_rate is checked against zero instead of NO_REGISTER.

* 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 kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. 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.

| | | | | | | | | The driver sends 3 bytes instead of 2 when accessing a register on the M09 firmware, so writing to gain seems to overflow into the offset register.
