@ -4,7 +4,7 @@ In the current snapdragon SoC's, we have (at least) 3 different
display controller blocks at play:

+ MDP4 - S3 (APQ8060, touchpad), S4-pro (APQ8064, nexus4 & ifc6410)

may have their own irqs which they install themselves. For this reason
the display controller is the "master" device.
For MDP5, the mapping is:
plane -> PIPE{RGBn,VIGn} \
crtc -> LM (layer mixer) |-> MDP "device"
encoder -> INTF /
connector -> HDMI/DSI/eDP/etc --> other device(s)
Unlike MDP4, it appears we can get by with a single encoder, rather
than needing a different implementation for DTV, DSI, etc. (Ie. the
register interface is same, just different bases.)
Also unlike MDP4, with MDP5 all the IRQs for other blocks (HDMI, DSI,
etc) are routed through MDP.
And finally, MDP5 has this "Shared Memory Pool" (called "SMP"), from
which blocks need to be allocated to the active pipes based on fetch
stride.
Each connector probably ends up being a separate device, just for the
logistics of finding/mapping io region, irq, etc. Idealy we would
have a better way than just stashing the platform device in a global

/* SMP - Shared Memory Pool
*
* These are shared between all the clients, where each plane in a
* scanout buffer is a SMP client. Ie. scanout of 3 plane I420 on
* pipe VIG0 => 3 clients: VIG0_Y, VIG0_CB, VIG0_CR.
*
* Based on the size of the attached scanout buffer, a certain # of
* blocks must be allocated to that client out of the shared pool.
*
* For each block, it can be either free, or pending/in-use by a
* client. The updates happen in three 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.
*
* 2) mdp5_smp_configure():
* As hw is programmed, before FLUSH, MDP5_SMP_ALLOC registers
* are configured for the union(pending, inuse)
*
* 3) mdp5_smp_commit():
* After next vblank, copy pending -> inuse. Optionally update
* MDP5_SMP_ALLOC registers if there are newly unused blocks
*
* 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).
*
* btw, hurray for confusing overloaded acronyms! :-/
*
* NOTE: for atomic modeset/pageflip NONBLOCK operations, step #1
* should happen at (or before)? atomic->check(). And we'd need
* an API to discard previous requests if update is aborted or
* (test-only).
*
* TODO would perhaps be nice to have debugfs to dump out kernel
* inuse and pending state of all clients..
