video: auo_k190x: add code shared by controller drivers
The AUO-K190X controllers share a very similar set of commands and can therefore also share most of the driver code. Signed-off-by: Heiko Stübner <heiko@sntech.de> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

Provides support for epaper controllers from the K190X series
|
||||
of AUO. These controllers can be used to drive epaper displays
|
||||
from Sipix.
|
||||
|
||||
This option enables the common support, shared by the individual
|
||||
controller drivers. You will also have to enable the driver
|

for the controller type used in your device.
