Commit 04647773 ("dt-bindings: input: Convert ChipOne ICN8318 binding to a schema") converts chipone_icn8318.txt to chipone,icn8318.yaml, but missed to adjust its reference in MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. Repair this file reference in CHIPONE ICN8318 I2C TOUCHSCREEN DRIVER. Signed-off-by:

Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding a SPI device ID table. Fixes: 96c8395e ("spi: Revert modalias changes") Signed-off-by:

The helper function devm_add_action_or_reset() will internally call devm_add_action(), and if devm_add_action() fails then it will execute the action mentioned and return the error code. So use devm_add_action_or_reset() instead of devm_add_action() to simplify the error handling, reduce the code. Signed-off-by:

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. Reviewed-by:

The config which needs to be send to the controller on some device-models is model-specific. Allow specifying a model-specific filename through a device-property, rather then always using a fixed filename.

Make the goodix_i2c_read() and goodix_i2c_write*() helpers log errors themselves. This allows removing all the error logging from their callers. This already results in a nice cleanup with the current code and it also helps to make the upcoming support for controllers without flash cleaner. Reviewed-by:

Hans de Goede authored
Refactor reset handling a bit, change the main reset handler into a new goodix_reset_no_int_sync() helper and add a goodix_reset() wrapper which calls goodix_int_sync() separately. Also push the dev_err() call on reset failure into the goodix_reset_no_int_sync() and goodix_int_sync() functions, so that we don't need to have separate dev_err() calls in all their callers. This is a preparation patch for adding support for controllers without flash, which need to have their firmware uploaded and need some other special handling too. Reviewed-by:

Add a goodix.h header file, and move the register definitions, and struct declarations there and add prototypes for various helper functions. This is a preparation patch for adding support for controllers without flash, which need to have their firmware uploaded and need some other special handling too. Since MAINTAINERS needs updating because of this change anyways, also add myself as co-maintainer. Reviewed-by:

Change the type of the goodix_i2c_write() len parameter to from 'unsigned' to 'int' to avoid bare use of 'unsigned', changing it to 'int' makes goodix_i2c_write()' prototype consistent with goodix_i2c_read(). Reviewed-by:

As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the struct_size() helper to do the arithmetic instead of the argument "size + count * size" in the kzalloc() function.

This adds support for Cypress StreetFighter touchkey controllers such as sf3155. This driver supports managing regulators and generating input events.
