2013-12-15Input: cyttsp - include appropriate header file in cyttsp_i2c_common.cRashika Kheria1-0/+2
Include cyttsp4_core.h in cyttsp_i2c_common.c to ensure that implementation of cyttsp_i2c_read_block_data() and cyttsp_i2c_write_block_data() match what the rest of the driver expects. Thus, it also eliminates the following warning in cyttsp_i2c_common.c: drivers/input/touchscreen/cyttsp_i2c_common.c:34:5: warning: no previous prototype for ‘cyttsp_i2c_read_block_data’ [-Wmissing-prototypes] drivers/input/touchscreen/cyttsp_i2c_common.c:64:5: warning: no previous prototype for ‘cyttsp_i2c_write_block_data’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@gmail.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2013-07-06Input: cyttsp4 - use 16bit address for I2C/SPI communicationFerruh Yigit1-8/+22
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.

2013-06-30Input: cyttsp - I2C driver split into two modulesFerruh Yigit1-0/+79
Existing I2C code is for TrueTouch Gen3 devices TrueTouch Gen4 device is using same protocol, will split driver into two pieces to use common code with both drivers. Read/Write functions parameter list modified, since shared code will be used by two separate drivers and these drivers are not sharing same structs, parameters updated to use common structures.
