Message

Add support to the reMarkable2 (rM2) for the Wacom I2C device.

This is based on the reMarkable Linux fork and with this series I am
able to use the Wacom digitiser on the rM2.

v10:
 - Add a new patch to determine the generation
 - Use generation to determine if tilt is supported
 - Address comments from v9
 - Remove flip-pressure
v9:
 - Add two new patches
 - Fixup the device tree interrupt line
v7:
 - Fx the compatible name and documentation
