Hi Soni, At first, I tried to support tsc2007 with ads7846.c. But it required some kind of common logic to support both SPI and I2C for the driver, as you thought. If I modified the ads7846.c to support tsc2007, the driver might be a bit more complicate. I do not know which method is better, but making a different driver was simppler for me.
