MLK-21509-4 drm/imx: dpu: crc: Add user-configurable CRC region(ROI) support
This patch adds user-configurable CRC region support.
The users may choose a region of interest(ROI) as the CRC source
(i.e., the CRC evaluation window) via the debugfs control node.
The ROI cannot exceed the display region as indicated by
drm_crtc_state->adjusted_mode. The users may write a string in
the fashion of "roi:x1,y1,x2,y2" to the node to specify the ROI
within the display region. The inclusive position at (x1, y1)
indicates the upper left of the region, while the exclusive
position at (x2, y2) indicates the lower right of the region.
