MLK-12425-2: video: epdc: introduce epdc support
Support EPDC.
E-Ink feature is supported by i.MX6DL/SL and i.MX7D.
For now this driver only supports i.MX6DL/SL, because the
i.MX7D EPDC driver needs pxp support which is not included
in U-Boot.
Support user defined logo file, if there is no logo file, it will
draw a black border around a white screen.
If need to enable EPDC, a waveform file is required to let all
work.
Since we need LCD_MONOCHROME mode for EPDC, we introduce LCD_MONOCHROME
support.
Please refer to Linux Reference Manual for how to flash WAVEFORM file.
