[PATCH 1/7] Input: cyttsp - Probe from compatibles

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
