* and CANNOT be re-allocated (eg: MMB0 and MMB1 both tied to RGB0).
*
* For each block that can be dynamically allocated, it can be either
* free, or pending/in-use by a client. The updates happen in three steps:
* free:
* The block is free.
*
* pending:
* The block is allocated to some client and not free.
*
* configured:
* The block is allocated to some client, and assigned to that
* client in MDP5_MDP_SMP_ALLOC registers.
*
* inuse:
* The block is being actively used by a client.
*
* The updates happen in the following steps:
*
* 1) mdp5_smp_request():
* When plane scanout is setup, calculate required number of
* blocks needed per client, and request. Blocks not inuse or
* pending by any other client are added to client's pending
* set.
* blocks needed per client, and request. Blocks neither inuse nor
* configured nor pending by any other client are added to client's
* pending set.
* For shrinking, blocks in pending but not in configured can be freed
* directly, but those already in configured will be freed later by
* mdp5_smp_commit.
*
* 2) mdp5_smp_configure():
* As hw is programmed, before FLUSH, MDP5_MDP_SMP_ALLOC registers
* are configured for the union(pending, inuse)
* Current pending is copied to configured.
* It is assumed that mdp5_smp_request and mdp5_smp_configure not run
* concurrently for the same pipe.
*
* 3) mdp5_smp_commit():
* After next vblank, copy pending -> inuse. Optionally update
* After next vblank, copy configured -> inuse. Optionally update
* MDP5_SMP_ALLOC registers if there are newly unused blocks
*
* 4) mdp5_smp_release():
* Must be called after the pipe is disabled and no longer uses any SMB
*
* On the next vblank after changes have been committed to hw, the
* client's pending blocks become it's in-use blocks (and no-longer
* in-use blocks become available to other clients).
