[PATCHv5 6/6] drm/omap: add support for manually updated displays

This adds the required infrastructure for manually updated displays, such as DSI command mode panels. While those panels often support partial updates we currently always do a full refresh. The display will be refreshed when something calls the dirty callback, such as libdrm's drmModeDirtyFB(). Th

[PATCHv5 3/6] drm/omap: don't check dispc timings for DSI

While most display types only forward their VM to the DISPC, this is not true for DSI. DSI calculates the VM for DISPC based on its own, but it's not identical. Actually the DSI VM is not even a valid DISPC VM making this check fail. Let's restore the old behaviour and avoid checking the DISPC VM f

Hi Dave, Thanks for your feedback. No issue found actually if I remove "volatile" on my platform. In my experience, if the value is volatile, adding "volatile" will be safer and no harm, that is why I add it by default. If you think it is not necessary, it's ok for me to remove it. Regards, Y.C.
