Input: cyttsp4 - remove driver

2024-08-05T17:48:49Z

The cyttsp4 touchscreen driver was contributed in 2013 and since then has seen no updates. The driver uses platform data (no device tree support) and there are no users of it in the mainline kernel. There were occasional fixes to it for issues either found by static code analysis tools or via visual inspection, but otherwise the driver is completely untested. Remove the driver.

Input: drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-13T22:43:19Z

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

Input: Switch i2c drivers back to use .probe()

2023-05-17T16:59:11Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

Input: cyttsp - use EXPORT_GPL_SIMPLE_DEV_PM_OPS()

2023-01-27T22:49:53Z

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and EXPORT_GPL_SIMPLE_DEV_PMU_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings. It also rolls in the EXPORT_SYMBOL() so that we only export it if CONFIG_PM_SLEEP.

Input: cyttsp_i2c - Convert to i2c's .probe_new()

2022-12-02T22:53:44Z

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-237-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

Input: cyttsp - remove public header

2021-06-02T04:13:11Z

There is nothing in include/linux/input/cyttsp.h that might be of interes to the kernel at large, so let's move this information into the driver code and remove the header.

Input: cyttsp - probe from compatibles

2021-05-26T23:58:59Z

The driver (both SPI and I2C interface) should probe from the compatible strings, cypress,cy8ctma340 etc when using device tree, not as now, where it is probing implicitly from the I2C/SPI node name "cypress,cyttsp-i2c" etc. Reviewed-by: Javier Martinez Canillas Signed-off-by: Linus Walleij Link: https://lore.kernel.org/r/20210526230352.1433537-2-linus.walleij@linaro.org Signed-off-by: Dmitry Torokhov

Input: cyttsp - remove unnecessary MODULE_ALIAS()

2015-09-03T17:56:19Z

The drivers have a I2C device ID table that is used to create the module aliases and also "cyttsp" and "cyttsp4" are not supported I2C device IDs so these module aliases are never used. Signed-off-by: Javier Martinez Canillas Signed-off-by: Dmitry Torokhov
