2015-10-02Input: auo-pixcir-ts - simplify function return logicJavier Martinez Canillas
The invoked function already returns zero on success or a negative errno code so there is no need to open code the logic in the caller. This also fixes the following make coccicheck warnings: end returns can be simplified and declaration on line 402 can be dropped Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-07-17Input: drop owner assignment from i2c_driverKrzysztof Kozlowski
i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-11-02Input: touchscreen - use __maybe_unused instead of ifdef around suspend/resumeJingoo Han
Use __maybe_unused instead of ifdef guards around suspend/resume functions, in order to increase build coverage and fix build warnings. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-05-14Input: auo-pixcir-ts - make of_device_id array constJingoo Han
Make of_device_id array const, because all OF functions handle it as const. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Acked-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

This simplifies error unwinding and device teardown. Tested-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2013-02-24Input: auo_pixcir_ts - add devicetree supportHeiko Stübner
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.

2013-02-24Input: auo_pixcir_ts - keep own pointer to platform_dataHeiko Stübner
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>
2013-02-24Input: auo-pixcir-ts - handle reset gpio directlyHeiko Stübner
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.

2011-12-27Input: add driver for AUO In-Cell touchscreens using pixcir ICsHeiko Stübner
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.
