[PATCH v10 00/12] Add Wacom I2C support to rM2

From: Alistair Francis
Date: Sun Aug 29 2021 - 05:19:51 EST


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
