* Input: cyttsp4 - remove driverDmitry Torokhov2024-08-051-0/+55
| | | | | | | | | | | | | | | | 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 0Uwe Kleine-König2024-05-141-1/+1
| | | | | | | | | | | | | | | 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()Uwe Kleine-König2023-05-171-1/+1
| | | | | | | | | | | | 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()Jonathan Cameron2023-01-271-1/+1
| | | | | | | | | | | | | | | | 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: add Cypress TTSP capacitive multi-touch screen supportJavier Martinez Canillas2012-01-311-0/+146
Cypress TrueTouch(tm) Standard Product controllers are found in a wide range of embedded devices. This driver add support for a variety of TTSP controllers. Since the hardware is capable of tracking identifiable contacts, multi-touch protocol type B (stateful) is used to report contact information. The driver is composed of a core driver that process the data sent by the contacts and a set of bus specific interface modules. This patch adds the base core TTSP driver.
