** WORK IN PROGRESS **
Parsing of waveform files is based on smaeuls (Samuel Holland [email protected]) work:
https://github.com/smaeul/linux/blob/rk35/ebc-drm-v5/drivers/gpu/drm/drm_epd_helper.c
copy your waveform image to 02_waveform.img and run ./waveform.py A new waveform file "test.bin" is then produced with modified A2 waveform.
