2022-01-08Input: zinitix - handle proper supply namesLinus Walleij
The supply names of the Zinitix touchscreen were a bit confused, the new bindings rectifies this. To deal with old and new devicetrees, first check if we have "vddo" and in case that exists assume the old supply names. Else go and look for the new ones. We cannot just get the regulators since we would get an OK and a dummy regulator: we need to check explicitly for the old supply name. Use struct device *dev as a local variable instead of the I2C client since the device is what we are actually obtaining the resources from.

2021-12-19Input: ti_am335x_tsc - lower the X and Y sampling timeDario Binacchi
The open delay time has to be applied only on the first sample of the X/Y coordinates because on the following samples the ADC channel is not changed. Removing this time from the samples after the first one, "ti,coordinate-readouts" greater than 1, decreases the total acquisition time, allowing to increase the number of acquired coordinates in the time unit.

2021-12-12Input: silead - add support for EFI-embedded fw using different min/max ↵Hans de Goede
coordinates Unfortunately, at the time of writing this commit message, we have been unable to get permission from Silead, or from device OEMs, to distribute the necessary Silead firmware files in linux-firmware. On a whole bunch of devices the UEFI BIOS code contains a touchscreen driver, which contains an embedded copy of the firmware. The fw-loader code has a "platform" fallback mechanism, which together with info on the firmware from drivers/platform/x86/touchscreen_dmi.c will use the firmware from the UEFI driver when the firmware is missing from /lib/firmware. This makes the touchscreen work OOTB without users needing to manually download the firmware. The firmware bundled with the original Windows/Android is usually newer then the firmware in the UEFI driver and it is better calibrated. This better calibration can lead to significant differences in the reported min/max coordinates. Add support for a new (optional) "silead,efi-fw-min-max" property which provides a set of alternative min/max values to use for the x/y axis when the EFI embedded firmware is used. The new property is only used on (x86) devices which do not use devicetree, IOW it is not used in actual devicetree files. The devicetree-bindings maintainers have requested properties like these to not be added to the devicetree-bindings, so the new property is deliberately not added to the existing silead devicetree-bindings documentation.

The info on how to detect when a pen is down and to detect when the stylus buttons are pressed was lifted from the out of tree Goodix driver with pen support written by Adya: https://gitlab.com/AdyaAdya/goodix-touchscreen-linux-driver/ Since there is no way to tell if pen support is present, the registering of the pen input_dev is delayed till the first pen event is detected.

2021-11-09Input: ili210x - reduce sample period to 15msMarek Vasut
Modern devices may redraw display at 60 Hz, make sure we have one input sample per one frame. Reduce sample period to 15ms, so we would get up to 66.6 samples per second, although realistically with all the jitter and extra scheduling wiggle room, we would end up just above 60 samples per second. This should be a good compromise between sampling too often and sampling too seldom.

2021-11-09Input: ili210x - improve polled sample spacingMarek Vasut
Currently the ili210x driver implements a threaded interrupt handler which starts upon edge on the interrupt line, and then polls the touch controller for samples. Every time a sample is obtained from the controller, the thread function checks whether further polling is required, and if so, waits fixed amount of time before polling for next sample. The delay between consecutive samples can thus vary greatly, because the I2C transfer required to retrieve the sample from the controller takes different amount of time on different platforms. Furthermore, different models of the touch controllers supported by this driver require different delays during retrieval of samples too. Instead of waiting fixed amount of time before polling for next sample, determine how much time passed since the beginning of sampling cycle and then wait only the remaining amount of time within the sampling cycle. This makes the driver deliver samples with equal spacing between them.

2021-10-16Input: ili210x - add ili251x firmware update supportMarek Vasut
The ili251x firmware can be updated, this is used when switching between different modes of operation of the touch surface, e.g. glove operation. This patch implements the firmware update mechanism triggered by a write into an sysfs attribute. The firmware itself is distributed as an intel hex file with non-standard types. The first two lines are of type 0xad, which indicates the start of DataFlash payload, that is always at address 0xf000 on the ili251x, so it can be dropped, and 0xac which indicates the position of firmware info in the Application payload, that is always at address 0x2020 on the ili251x and we do not care. The rest of the firmware is data of type 0x00, and we care about that. To convert the firmware hex file into something usable by the kernel, remove the first two lines and then use ihex2fw: $ tail -n +3 input.hex > temp.hex $ ./tools/firmware/ihex2fw temp.hex firmware/ilitek/ili251x.bin To trigger the firmware update, place firmware file ilitek/ili251x.bin into /lib/firmware/, write into firmware_update sysfs attribute and wait about 30-40 seconds. The firmware update is slow. Afterward, verify the firmware_version and mode sysfs attributes to check whether the firmware got updated and the controller switched back to application (AP) mode by reading out 'mode' attribute in sysfs. Note that the content of firmware_version, e.g. 0600.0005.abcd.aa04 can be matched to the content of the firmware hex file. The first four bytes, 0x06 0x00 0x00 0x05 can be found at ^:102030 00 05000006, the next four bytes 0xab 0xcd 0xaa 0x04 at ^:10F000 00 nnnnnnnn ABCDAA04. Note that the protocol differs considerably between the ili2xxx devices, this patch therefore implements this functionality only for ili251x that I can test.

2021-10-16Input: ili210x - export ili251x version details via sysfsMarek Vasut
The ili251x firmware protocol permits readout of firmware version, protocol version, mcu version and current mode (application, boot loader, forced update). These information are useful when updating the firmware on the il251x, e.g. to avoid updating the same firmware into the device multiple times. The locking is now necessary to avoid races between interrupt handler and the sysfs readouts. Note that the protocol differs considerably between the ili2xxx devices, this patch therefore implements this functionality only for ili251x that I can test.

This way, older DTs which contain touchscreen-size-x and touchscreen-size-y properties will behave just like before and new DTs may avoid specifying these for ILI251x. Note that the command format is different on other controllers, so this functionality is isolated to ILI251x.

2021-10-11Input: st1232 - increase "wait ready" timeoutJohn Keeping
I have a ST1633 touch controller which fails to probe due to a timeout waiting for the controller to become ready. Increasing the minimum delay to 100ms ensures that the probe sequence completes successfully. The ST1633 datasheet says nothing about the maximum delay here and the ST1232 I2C protocol document says "wait until" with no notion of a timeout. Since this only runs once during probe, being generous with the timout seems reasonable and most likely the device will become ready eventually. (It may be worth noting that I saw this issue with a PREEMPT_RT patched kernel which probably has tighter wakeups from usleep_range() than other preemption models.)

2021-09-20Input: goodix - add support for controllers without flashHans de Goede
Some Goodix touchscreen controllers, such as for example the GT912, don't have flash-storage for their firmware. These models require the OS to load the firmware at runtime, as well as some other special handling. Add support for this to the goodix driver. This patch was developed and tested on a Glavey TM800A550L tablet. Note the "goodix,main-clk" and "firmware-name" device-properties used by the new code are *not* documented in the Documentation/devicetree/bindings/input/touchscreen/goodix.yaml device-tree bindings for now. Not documenting these is intentional. This is done because this code has only been tested on x86/ACPI so far, where devicetree is not used. Instead these properties are set through a software-fwnode attached to the device by the drivers/platform/x86/touchscreen_dmi.c code. This means that the use of this properties for now is purely a kernel-internal thing and the name/working of the properties may still be changed for now.

2021-09-09Input: ads7846 - remove custom filter handling functions from pdataDaniel Mack
The functions in the platform data struct to initialize, cleanup and apply custom filters are not in use by any mainline board. Remove support for them to pave the road for more cleanups to come. The enum was moved as it has no users outside of the driver code itself.

2021-06-19Input: hideep - fix the uninitialized use in hideep_nvm_unlock()Yizhuo Zhai
Inside function hideep_nvm_unlock(), variable "unmask_code" could be uninitialized if hideep_pgm_r_reg() returns error, however, it is used in the later if statement after an "and" operation, which is potentially unsafe.
