git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input Pull input fix from Dmitry Torokhov: "A small fixup to the Zinitix touchscreen driver to avoid enabling the IRQ line before we successfully requested it" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: zinitix - make sure the IRQ is allocated before it gets enabled
2022-01-08Input: zinitix - make sure the IRQ is allocated before it gets enabledNikita Travkin
Since irq request is the last thing in the driver probe, it happens later than the input device registration. This means that there is a small time window where if the open method is called the driver will attempt to enable not yet available irq. Fix that by moving the irq request before the input device registration.

2021-12-06Input: goodix - try not to touch the reset-pin on x86/ACPI devicesHans de Goede
Unless the controller is not responding at boot or after suspend/resume, the driver never resets the controller on x86/ACPI platforms. The driver still requesting the reset pin at probe() though in case it needs it. Until now the driver has always requested the reset pin with GPIOD_IN as type. The idea being to put the pin in high-impedance mode to save power until the driver actually wants to issue a reset. But this means that just requesting the pin can cause issues, since requesting it in another mode then GPIOD_ASIS may cause the pinctrl driver to touch the pin settings. We have already had issues before due to a bug in the pinctrl-cherryview.c driver which has been fixed in commit 921daeeca91b ("pinctrl: cherryview: Preserve CHV_PADCTRL1_INVRXTX_TXDATA flag on GPIOs"). And now it turns out that requesting the reset-pin as GPIOD_IN also stops the touchscreen from working on the GPD P2 max mini-laptop. The behavior of putting the pin in high-impedance mode relies on there being some external pull-up to keep it high and there seems to be no pull-up on the GPD P2 max, causing things to break. This commit fixes this by requesting the reset pin as is when using the x86/ACPI code paths to lookup the GPIOs; and by not dropping it back into input-mode in case the driver does end up issuing a reset for error-recovery.

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.

According to downstream ili251x example code, this 5ms delay is not required when reading touch samples out of the controller. Implement such a special case.

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.

The ili251x firmware protocol permits readout of panel resolution, implement this, but make it possible to override this value using DT bindings. 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.
