/* Surface update type is used by dc_update_surfaces_and_stream
* The update type is determined at the very beginning of the function based

* going to be done during the call.
*
* UPDATE_TYPE_FAST is used for really fast updates that do not require much
* logical calculations or hardware register programming. This update MUST be
* ISR safe on windows. Currently fast update will only be used to flip surface
* address.
*
* UPDATE_TYPE_MED is used for slower updates which require significant hw
* re-programming however do not affect bandwidth consumption or clock
* requirements. At present, this is the level at which front end updates
* that do not require us to run bw_calcs happen. These are in/out transfer func
* updates, viewport offset changes, recout size changes and pixel depth changes.
* This update can be done at ISR, but we want to minimize how often this happens.
*
* UPDATE_TYPE_FULL is slow. Really slow. This requires us to recalculate our
* bandwidth and clocks, possibly rearrange some pipes and reprogram anything front
* end related. Any time viewport dimensions, recout dimensions, scaling ratios or
* gamma need to be adjusted or pipe needs to be turned on (or disconnected) we do
* a full update. This cannot be done at ISR level and should be a rare event.
* Unless someone is stress testing mpo enter/exit, playing with colour or adjusting
* underscan we don't expect to see this call at all.
