2014-04-03Input: edt-ft5x06 - add a missing conditionDan Carpenter
The if condition was accidentally deleted here so we return every time instead of returning on error. Fixes: fd335ab04b3f ('Input: edt-ft5x06 - add support for M09 firmware version') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Jingoo Han <jg1.han@samsung.com> Acked-By: Lothar Waßmann <LW@KARO-electronics.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-03-28Input: edt-ft5x06 - add support for M09 firmware versionLothar Waßmann
There is a new firmware version for the EDT-FT5x06 chip. Add support for detecting the firmware version and handle the differences appropriately. Signed-off-by: Lothar Waßmann <LW@KARO-electronics.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-03-28Input: edt-ft5x06 - ignore touchdown eventsLothar Waßmann
The chip may report invalid coordinates on touchdown events, so don't report the initial touchdown event. Signed-off-by: Lothar Waßmann <LW@KARO-electronics.de> Acked-by: Fugang Duan <B38611@freescale.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-03-28Input: edt-ft5x06 - adjust delays to conform datasheetLothar Waßmann
The FT5x06 datasheet specifies a minimum reset width of 5ms and a delay between deassertion of reset and start of reporting of 300ms. Adjust the delays to conform to the datasheet. With the original delays I sometimes experienced communication timeouts when initializing the controller.

2013-12-06Input: use dev_get_platdata()Jingoo Han
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability.
