The timings here look slightly strange. Typically

.{h,v}display < .{h,v}sync_start < .{h,v}hsync_end < .{h,v}total

Given your timings above essentially means that the vsync pulse starts
immediately after the last active pixel or line and is of length zero.

This size is the physical size (in mm) of the active area of the panel.

This patch should also be adding a device tree binding document for this
panel.
