| Subject | [PATCH 3/7] video: fbdev: pmag-aa-fb: Report video timings |
| Message-ID | <r4NX4-6FN-17@gated-at.bofh.it> |
The board uses hardwired timings compatible with 72Hz DEC VR319-DA and
VRM17-AA monitors, according to the board owner's manual[1]. These
timings are accordingly taken from the VR319 manual[2].
