Now I want to bring up one touch panel driver. But I cannot find some detail information about I2C and GPIO.
I2C SDA connect to I2C_GP0_DAT_1V8,
I2C SCL connect to I2C_GP0_CLK_1V8
If the I2C BUS No is 2, i2c@7000c400?
GPIO INT connect to GPIO_EXP0_INT
GPIO RST connect to TCA9539_RST_L
If the INT GPIO Number is TEGRA_GPIO(L,1) and RST GPIO Number is TEGRA_GPIO(L,3)?
Where can I download some documents about I2C and GPIO configure.
