2013-07-07Input: cyttsp4 - use 16bit address for I2C/SPI communicationFerruh Yigit1-11/+9
In TSG4, register map is 512bytes long and to access all of it, one bit from address byte is used (which bit to use differs for I2C and SPI); Since common code used for TSG3 and TSG4 for I2C, this parameter wrongly used as u8. TSG3 does not access beyond 255 bytes but TSG4 may.
