[PATCH 0/3] Add support for PocketBook Touch Lux 3 e-book reader

[PATCH 0/3] Add support for PocketBook Touch Lux 3 e-book reader

[Ondrej Jirman]

This series adds a fairly complete support for this e-book reader.

Missing parts are eink display driver and the touch panel driver.
Support for both is available out-of-tree for now at:
  https://megous.com/git/linux/log/?h=pb-5.6

The rest of the board is supported by the mainline drivers.

Please take a look.

thank you and regards,
  Ondrej Jirman
