This series adds basic support for the AUO-K190X family of epaper controllers which consists at the moment of the K1900 and K1901. These controllers are used mostly in the OEM line of Qisda ebook readers sold under different brands worldwide. Among those are the Medion/Thalia Oyo 1 + 2, the bq Avant and Avant 3, the Asus eeeReader DR-900, BenQ K60 and dozens more. The _dpy_update, _dpy_update_pages and _need_refresh functions are intentional duplicated. Currently they do the same, but as the controllers emit a greatly different runtime behaviour there is a lot of room for future controller-specific performance improvements. The series also includes the patch which adds a first_io callback to defio. This creates a nice way to parallelise the wakup when it is known that the controller is needed at the end of the defio cycle.
