This switches the driver over to the standard touchscreen properties for coordinate transformation, while keeping old bindings working as well. Tested-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
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 <linus.walleij@linaro.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
This driver can use GPIO descriptors rather than GPIO numbers without any problems, convert it. Name the field variables after the actual pins on the chip rather than the "reset" and "touch" names from the devicetree bindings that are vaguely inaccurate. No in-tree users pass GPIO numbers in platform data so drop this. Descriptor tables can be used to get these GPIOs from a board file if need be.

A few vendor specific bindings are now covered by common bindings. Let the driver parse the common bindings to make use of common inverting and swapping mechnism. Aslo make use of touchscreen_report_pos() to ensure the correct inverting-swapping order. The vendor specific properties are used as default (backward compatibility) and gets overwritten by common bindings.

Sync up with mainline to bring in the latest APIs.
This patch adds support for the Azoteq IQS550/572/525 family of trackpad/touchscreen controllers. The driver has been tested with an IQS550EV02 evaluation board. A demonstration of the driver's capabilities is available here: https://youtu.be/sRNNx4XZBts Signed-off-by: Jeff LaBundy <jeff@labundy.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
GT5663 is capacitive touch controller with customized smart wakeup gestures. Add support for it by adding compatible and supported chip data. The chip data on GT5663 is similar to GT1151, like - config data register has 0x8050 address - config data register max len is 240 - config data checksum has 16-bit Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
