Input: bu21013_ts - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2023-01-10T04:25:24+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 DEFINE_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.

Input: bu21013_ts - Convert to i2c's .probe_new()

2022-12-02T22:53:44+00:00

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/20221118224540.619276-230-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

The value returned by an i2c 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: bu21013_ts - switch to using standard touchscreen properties

2019-09-02T16:07:38+00:00

This switches the driver over to the standard touchscreen properties for coordinate transformation, while keeping old bindings working as well. Tested-by: Linus Walleij Signed-off-by: Dmitry Torokhov

Input: bu21013_ts - switch to using MT-B (slotted) protocol

2019-09-02T16:07:38+00:00

MT-B protocol is more efficient and everyone expects it. We use in-kernel tracking to identify contacts. Tested-by: Linus Walleij Signed-off-by: Dmitry Torokhov

Input: bu21013_ts - fix suspend when wake source

2019-09-02T16:07:37+00:00

If the touchscreen is configured as wakeup source we should not be cutting off power to it. Also, now that the driver relies on I2C client to supply IRQ, we do not need to explicitly enable and disable IRQ for wakeup: if device is created as wakeup source, I2C core will mark interrupt as wakeup one.

Input: bu21013_ts - use interrupt from I2C client

2019-09-02T16:07:18+00:00

Instead of trying to map INT GPIO to interrupt, let's use one supplied by I2C client. If there is none - bail. This will also allow us to treat INT GPIO as optional, as per the binding. Tested-by: Linus Walleij Signed-off-by: Dmitry Torokhov

Input: bu21013_ts - remove support for platform data

2019-09-02T16:07:17+00:00

There are no current users of the platform data in the tree, and any new users should either use device tree, or static device properties to describe the device. This change drop the platform data definition and handling and moves the driver over to generic device properties API. We also drop support for the external clock. If it is needed we will have to extend the bindings to supply the clock reference and handle it properly in the driver. Also, wakeup setting should be coming from I2C client.

Input: bu21013_ts - convert to using managed resources

2019-09-02T16:07:17+00:00

This allows trimming error unwinding and device removal handling. Tested-by: Linus Walleij Signed-off-by: Dmitry Torokhov

Input: bu21013_ts - remove useless comments

2019-09-02T16:07:16+00:00

The comments for individual functions in the driver do not provide any additional information beyond what function names indicate. Tested-by: Linus Walleij Signed-off-by: Dmitry Torokhov
