The MMS114 platform data has no in-tree users, so drop it. Switch to using the standard touchscreen properties via touchscreen_parse_properties(), and move the old DT parsing code to use device_property_*() APIs. Finally, use touchscreen_report_pos to report x/y coordinates and drop the custom x/y inversion code. Signed-off-by:

mms14 is a touchscreen and thus a direct input device; let's mark it as such. This also allows us to drop some initialization code as input_init_mt_slots() will do that for us. Also add error handling for input_mt_init_slots(). Reviewed-by:

When attempting enter factory mode on firmware that does not support it, we'd error out, but leave the device with interrupts disabled, and thus touch not working. Fix it by moving the check before we disable interrupts/allocate memory for debug buffers. Fixes: fd335ab0 ("Input: edt-ft5x06 - add support for M09 firmware version") Reviewed-by:

The interrupt is requested before the device is powered on and it's value in some cases cannot be reliable. It happens on some devices that an interrupt is generated as soon as requested before having the chance to disable the irq. Set the irq flag as IRQ_NOAUTOEN before requesting it. This patch mutes the error: stmfts 2-0049: failed to read events: -11 received sometimes during boot time. Signed-off-by:

To ease analyzing boot behavior from logs, let's log when we are about to register the pass-through serio port. Also, let's drop "Synaptics" prefix from the port name, as RMI4 is good enough indicator already, and having the prefix means that the name does not fit into serio->name field. While at it move from hard-coded seio->phys to one mentioning the sensor ID (such as "rmi4-00.fn03/serio0"). Reviewed-by:

Currently we register the pass-through serio port when we probe the F03 RMI function, and then, in sensor configure phase, we unmask interrupts. Unfortunately this is too late, as other drivers are free probe devices attached to the serio port as soon as it is probed. Because interrupts are masked, the IO times out, which may result in not being able to detect trackpoints on the pass-through port. To fix the issue we implement open() and close() methods for the pass-through serio port and unmask interrupts from there. We also move creation of the pass-through port form probe to configure stage, as RMI driver does not enable transport interrupt until all functions are probed (we should change this, but this is a separate topic). We also try to clear the pending data before unmasking interrupts, because some devices like to spam the system with multiple 0xaa 0x00 announcements, which may interfere with us trying to query ID of the device.

We want to free memory reserved for interrupt mask handling only after we free functions, as function drivers might want to mask interrupts. This is needed for the followup patch to the F03 that would implement unmasking and masking interrupts from the serio pass-through port open() and close() methods.

Since AVR32 arch is gone, atmel-wm97xx driver is useless. In theory it could have been rewritten to work with AT91 devices, but the driver is from the platform data era, and a bit hard coded to work on AVR32 hardware variant of the AC97C peripheral, so let's remove it. Signed-off-by:

There is no need to #define the license of the driver, just put it in the MODULE_LICENSE() line directly as a text string. This allows tools that check that the module license matches the source code license to work properly, as there is no need to unwind the unneeded dereference. For some of these drivers, the #define is just a few lines above the MODULE_LICENSE() line, which is extra pointless. Reported-by:

input_mt_init_slots() resets the ABS_X/Y fuzz to 0 and expects the driver to call input_mt_report_pointer_emulation(). That is based on the MT position bits which are already defuzzed - hence a fuzz of 0. In the case of synaptics semi-mt devices, we report the ABS_X/Y axes manually. This results in the MT position being defuzzed but the single-touch emulation missing that defuzzing. Work around this by re-initializing the ABS_X/Y axes after the MT axis to get the same fuzz value back. https://bugs.freedesktop.org/show_bug.cgi?id=104533Signed-off-by:

We should not try to do any i2c transfers before the controller is resumed (which happens before our resume method gets called). So we need to disable our IRQ while suspended to enforce this. The code paths for devices with GPIOs for the int and reset pins already disable the IRQ the through goodix_free_irq(). This commit also disables the IRQ while suspended for devices without GPIOs for the int and reset pins. This fixes the i2c bus sometimes getting stuck after a suspend/resume causing the touchscreen to sometimes not work after a suspend/resume. This has been tested on a GPD pocked device.

The input events use struct timeval to store event time, unfortunately this structure is not y2038 safe and is being replaced in kernel with y2038 safe structures. Because of ABI concerns we can not change the size or the layout of structure input_event, so we opt to re-interpreting the 'seconds' part of timestamp as an unsigned value, effectively doubling the range of values, to year 2106. Newer glibc that has support for 32 bit applications to use 64 bit time_t supplies __USE_TIME_BITS64 define [1], that we can use to present the userspace with updated input_event layout. The updated layout will cause the compile time breakage, alerting applications and distributions maintainers to the issue. Existing 32 binaries will continue working without any changes until 2038. Ultimately userspace applications should switch to using monotonic or boot time clocks, as realtime clock is not very well suited for input event timestamps as it can go backwards (see a80b83b7 "Input: evdev - add CLOCK_BOOTTIME support" by by John Stultz). With monotonic clock the practical range of reported times will always fit into the pair of 32 bit values, as we do not expect any system to stay up for a hundred years without a single reboot.

On some x86 tablets with a silead touchscreen the windows logo on the front is a capacitive home button. Touching this button results in a touch with bits 12-15 of the Y coordinates set, while normally only the lower 12 are used. Detect this and report a KEY_LEFTMETA press when this happens. Note for now we only respond to the Y coordinate bits 12-15 containing 0x01, on some tablets *without* a capacative button I've noticed these bits containing 0x04 when crossing the edges of the screen.

This driver was merged in 2011 as a tool for detecting the orientation of a screen. The device driver assumes board file setup using the platform data from <linux/input/gpio_tilt.h>. But no boards in the kernel tree defines this platform data. As I am faced with refactoring drivers to use GPIO descriptors and pass decriptor tables from boards, or use the device tree device drivers like these creates a serious problem: I cannot fix them and cannot test them, not even compile-test them with a system actually using it (no in-tree boardfile). I suggest to delete this driver and rewrite it using device tree if it is still in use on actively maintained systems. I can also offer to rewrite it out of the blue using device tree if someone promise to test it and help me iterate it. Signed-off-by:
