2023-05-17Input: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+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.

2023-01-10Input: auo-pixcir-ts - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()Jonathan Cameron1-5/+5
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.

2022-09-16Input: auo-pixcir-ts - do not force rising edge interrupt triggerDmitry Torokhov1-1/+1
Instead of hard-coding rising edge as the interrupt trigger, let's rely on the platform (ACPI, DT) to configure the interrupt properly.

2022-09-16Input: auo-pixcir-ts - drop support for platform dataDmitry Torokhov1-62/+56
Currently there are no users of auo_pixcir_ts_platdata in the mainline, and having it (with legacy gpio numbers) prevents us from converting the driver to gpiod API, so let's drop it. If, in the future, someone wants to use this driver on non-device tree, non-ACPI system, they should use static device properties instead of platform data.

2019-07-13Input: auo-pixcir-ts - switch to using devm_add_action_or_reset()Fuqian Huang1-2/+1
devm_add_action_or_reset() is introduced as a helper function which internally calls devm_add_action(). If devm_add_action() fails then it will execute the action mentioned and return the error code. This reduce source code size (avoid writing the action twice) and reduce the likelyhood of bugs.

2013-02-25Input: auo_pixcir_ts - add devicetree supportHeiko Stübner1-5/+69
Add the necessary code to create the needed platformdata from devicetree informations. The interrupt mode of the chip is not set via devicetree, as it is not a property of the hardware but instead only a preferred type of operation. This should probably be made settable via configfs in the future. The option set as default is the mode the datasheet mentions as default.

2013-02-25Input: auo_pixcir_ts - keep own pointer to platform_dataHeiko Stübner1-5/+6
When supporting devicetree the platformdata may not necessarily come from the dev but may be generated in the driver instead. Therefore keep the pointer in the driver struct instead of using dev.platform_data. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2013-02-25Input: auo-pixcir-ts - handle reset gpio directlyHeiko Stübner1-6/+20
Devicetree based platforms don't handle device callbacks very well and until now no board has come along that needs more extended hwinit than pulling the rst gpio high. Therefore pull the reset handling directly into the driver and remove the callbacks from the driver. If extended device setup is needed at some later point, power-sequences would probably be the solution of choice.

2011-12-28Input: add driver for AUO In-Cell touchscreens using pixcir ICsHeiko Stübner1-0/+652
Some displays from AUO have a so called in-cell touchscreen, meaning it is built directly into the display unit. Touchdata is gathered through PIXCIR Tango-ICs and processed in an Atmel ATmega168P with custom firmware. Communication between the host system and ATmega is done via I2C. Devices using this touch solution include the Dell Streak5 and the family of Qisda ebook readers. The driver reports single- and multi-touch events including touch area values.
