Input: tsc2004/5 - fix handling of VIO power supply

2024-08-05T01:10:40+00:00

The chip needs to be powered up before calling tsc200x_stop_scan() which communicates with it; move the call to enable the regulator earlier in tsc200x_probe(). At the same time switch to using devm_regulator_get_enable() to simplify error handling. This also makes sure that regulator is not shut off too early when unbinding the driver.

Input: tsc2004/5 - use device core to create driver-specific device attributes

2023-09-06T21:29:03+00:00

Instead of creating driver-specific device attributes with sysfs_create_group() have device core do this by setting up dev_groups pointer in the driver structure.

Input: tsc200x - use EXPORT_GPL_SIMPLE_DEV_PM_OPS()

2023-01-27T22:49:53+00:00

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_PM_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. This function also removes the need for separate EXPORT_SYMBOL_GPL() Signed-off-by: Jonathan Cameron Link: https://lore.kernel.org/r/20230114171620.42891-10-jic23@kernel.org Signed-off-by: Dmitry Torokhov

spi: make remove callback a void function

2022-02-09T13:00:45+00:00

The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

Input: tsc200x - make tsc200x_remove() return void

2021-10-13T02:48:54+00:00

Up to now tsc200x_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c and spi remove callbacks is ignored anyway.

Input: tsc200x - report proper input_dev name

2016-07-21T00:50:24+00:00

Passes input_id struct to the common probe function for the tsc200x drivers instead of just the bustype. This allows for the use of the product variable to set the input_dev->name variable according to the type of touchscreen used. Note that when we introduced support for TSC2004 we started calling everything TSC200X, so let's keep this quirk.
