linux-toradex.git/drivers/input/touchscreen/ad7879-i2c.c, branch v4.9.96 Linux kernel for Apalis and Colibri modules Input: ad7879 - add device tree support 2016-03-08T18:51:18+00:00 Stefan Agner stefan@agner.ch 2016-03-08T18:35:24+00:00 fa6e3ca274429b66e12d06abc5a6c013cef66471 Add device tree support for the I2C and SPI variant of AD7879(-1). This allows to specify the touchscreen controller as a I2C client node or SPI slave device. Most of the options available in platform data are also available as device tree properties, the only exception being GPIO capabilities, which can not be activated through device tree currently.
