One is the normal bank, and the other one is the test bank, it means it have the same register address in the normal bank and test bank seperately. For test bank register, it needs a special I2C sequence to acess as below, Touching to 0xFA address Touching to 0xFB address Touching to 0xFF address Accessing bank register Touching to 0xFE address Touching to 0xFC address This sequence can't be interrupted. It means that we can't use i2c_transfef() to implement touching 0xFA address. Otherwise, other i2c operation may be inserted into 0xFA and 0xFB operation since the lock of i2c_adapter is already released.

However, setting it from the userspace focibly is not appropriate. And showing the state can be handled from other places (e.g. external connector) in a unified manner. This patch removes the sysfs attribute. Plus, uevent messages for interrupts are also removed.

Current implementation only supports I2C and all code is present in a single file stmpe.c. It would be better to separate out I2C interface specific code from controller specific code. Later SPI specific code can be added in a separate file. This patch separates out I2C and controller specific code into separate files, making stmpe.c independent of I2C.
