Other than that, the patch looks good to me. Reviewed-by: Javier Martinez Canillas <javier@dowhile0.org> Best regards, Javier

The driver (both SPI and I2C interface) should probe from the compatible strings, cypress,cy8ctma340 etc when using device tree, not as now, where it is probing implicitly from the I2C/SPI node name "cypress,cyttsp-i2c" etc. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> --- drivers/input/touchscreen/cyttsp_i2c.c | 7 +++++++ drivers/input/touchscreen/cyttsp_spi.c | 7 +++++++ 2 files changed, 14 insertions(+)
