Do not use kernel-doc style for comment describing contents of the source file, as it trips the script: scripts/kernel-doc -none drivers/input/misc/twl4030-pwrbutton.c drivers/input/misc/twl4030-pwrbutton.c:2: info: Scanning doc for function twl4030 drivers/input/misc/twl4030-pwrbutton.c:33: warning: expecting prototype for twl4030(). Prototype was for PWR_PWRON_IRQ() instead 1 warnings Also remove file name from the same comment - it it not the best idea to have it as they tend to get stale when sources get moved or renamed.

The HX83100A is a bit of an outlier in the Himax HX831xxx series of touch controllers as it requires reading touch events through the AHB interface of the MCU rather than providing a dedicated FIFO address like the other chips do. This patch implements the specific read function and introduces the HX83100A chip with an appropriate i2c ID and DT compatible string. The HX83100A doesn't have a straightforward way to do chip identification, which is why it is not implemented in this patch. Tested on: Lenovo ThinkSmart View (CD-18781Y) / Innolux P080DDD-AB2 LCM Signed-off-by:

Himax uses an AHB-style bus to communicate with different parts of the display driver and touch controller system. Use more descriptive names for the register and address defines. The names were taken from a driver submission for the similar HX83102J chip. Signed-off-by:

Add a compatible string for the Himax HX83100A touch controller. The HX83100A presents touch events on the internal bus rather than offering a dedicated event register like the other chips in this family do. Signed-off-by:

Now that the input_dev->vals array is always there we can be assured that input_pass_values() is always called with a non-0 number of events. Remove the check. Reviewed-by:

Preallocate memory for holding event values (input_dev->vals) so that there is no need to check if it was allocated or not in the event processing code. The amount of memory will be adjusted after input device has been fully set up upon registering device with the input core. Reviewed-by:

Streamline event handling code by providing batch implementations for filtering and event processing and using them in place of the main event handler, as needed, instead of having complex branching logic in the middle of the event processing code. Reviewed-by:

In preparation to consolidating filtering and event processing in the input core change events() method to return number of events processed by it. Reviewed-by:
-
Dmitry Torokhov authored
Input core expects input handlers to be either filters, or regular handlers, but not both. Additionally, for regular handlers it does not make sense to define both single event method and batch method. Refuse registering handler if it defines more than one method. Reviewed-by:

Dmitry Torokhov authored
Input core favors ->events() (batch) method over ->event() method if the former is defined, so there is no point in defining evdev_event() as it is never called. Remove it. Reviewed-by:

Imagis IST3038 is another variant of Imagis IST3038 IC, which has a different register interface from IST3038C (possibly firmware defined). Unlike IST3038C/IST3032C, IST3038 has different registers for commands, which means IST3038 doesn't use protocol B. Similar to IST3032C and maybe the other variants, IST3038 has touch keys support, which provides KEY_APPSELECT and KEY_BACK. Add support for IST3038 with touch keys. Signed-off-by:

When dealing with byte data use u8 instead of unsigned char or int. Stop layering error handling in cypress_ps2_sendbyte() and simply pass on error code from ps2_sendbyte(). Additionally use u8 instead of unisgned char throughout the code. Link: https://lore.kernel.org/r/20240628224728.2180126-5-dmitry.torokhov@gmail.comSigned-off-by:

Stop layering error handling in cypress_ps2_sendbyte() and simply pass on error code from ps2_sendbyte() and use it in the callers. This fixes mishandling of error condition in cypress_ps2_read_cmd_status() which expects errors to be negative. Reported-by:

Allocating a contiguous buffer of 64K may fail if memory is sufficiently fragmented, and may cause OOM kill of an unrelated process. However we do not need to have contiguous memory. We also do not need to zero out the buffer since it will be overwritten with firmware data. Switch to using kvmalloc() instead of kzalloc().
