[PATCH 2/2] dt-bindings: Add I2C attached EETI EXC3000 bindings
From: Ahmet Inan <hidden>
Date: 2017-10-06 07:37:28

linux-devicetree
Subsystem:
input (keyboard, mouse, joystick, touchscreen) drivers, open firmware and flattened device tree bindings, the rest · Maintainers:

This documents the use of the dt-bindings for the EETI EXC3000 driver with the following example configuration: Using the I2C address 0x2a of the touch controller in the driver. Using pin 9 as low level-sensitive interrupt to signal the driver. Using a 4096x4096 touch screen resolution. Inverting the x-axis and swapping the result with the y-axis.
