2021-06-06Input: resistive-adc-touch - fix uninitialized variable 'press'Colin Ian King1-3/+1
In the case where st->ch_map[GRTS_CH_PRESSURE] < GRTS_MAX_CHANNELS is false and also st->ch_map[GRTS_CH_Z1] < GRTS_MAX_CHANNELS is false the variable press is not initialized and contains garbage. In this situation st->pressure is also false, so we do not actually use press value, but it is impossible for the compiler to realize this, and it emits "uninitialized variable" warning. Fix this by initializing press to 0 and allows us to also remove an else clause that sets press to 0.

On Qualcomm Technologies, Inc. PMIC PMK8350, the PON peripheral is split into two peripherals: PON_HLOS and PON_PBS.

2021-06-02Input: edt-ft5x06 - add support for iovcc-supplyStephan Gerhold1-2/+36
At the moment, the edt-ft5x06 driver can control a single regulator ("vcc"). However, some FocalTech touch controllers have an additional IOVCC pin that should be supplied with the digital I/O voltage. The I/O voltage might be provided by another regulator that should also be kept on. Otherwise, the touchscreen can randomly stop functioning if the regulator is turned off because no other components still require it. Implement (optional) support for also enabling an "iovcc-supply". The datasheet specifies a delay of ~ 10us before enabling VDD/VCC after IOVCC is enabled, so make sure to enable IOVCC first.

2021-04-10Input: elantech - Prepare a complete software node for the deviceHeikki Krogerus1-2/+4
Creating a software node and supplying that for the device instead of only the device properties in it. A software node was always created in any case to hold the additional device properties, so this change does not have any real effect. This change makes it possible to remove support for the problematic "dangling" device properties from i2c subsystem, i.e. the "properties" member from struct i2c_board_info. The problems caused by them are not related to this driver.

2021-04-10Input: cyttsp - drop the phys pathLinus Walleij2-3/+0
When I test to use the CY8CTMA340 with PostmarketOS I don't have any problem whatsoever in dropping this phys path, it finds and uses the touchscreen just as well. I suppose it is because userspace is using modern input libraries. I challenge the maintainers to point out a valid and still used userspace that actually need this. I say we drop it.

2021-04-10Input: cyttsp - reduce reset pulse timingsLinus Walleij1-2/+8
The data sheet for CY8CTMA340 specifies that the reset pulse shall be at least 1 ms. Specify 1-2 ms with usleep_range() to cut some slack for the scheduler. Curiously the datasheet does not specify how long we have to wait after a hard reset until the chip is up, but I have found a vendor tree (Samsung GT-S7710) that has code for this touch screen and there this is set to 5 ms so I use this with the same 1 ms fuzz.

The Melfas MMS136 is similar to the other MMS variants but has event packages of 6 bytes rather than 8 as the others. The define is named FINGER_EVENT_SZ in the vendor drivers so I renamed it from MMS*_PACKET_SZ to MMS*_EVENT_SZ. After this patch, the touchscreen on the Samsung GT-I8530 works fine with PostmarketOS.
