TVout hardware block is responsible to dispatch the data flow coming from compositor block to any of the output (HDMI or Analog TV). It control when output are start/stop and configure according the require flow path.
TVout is the parent of HDMI and HDA drivers and bind them at runtime.

hmm, I do wonder a bit whether it would make more sense to split sti_connector into a bridge + connector, and move stuff like set_mode() into the bridge half of it? Normally that sort of thing would make more sense in the encoder, but for msm I actually have separate hw blocks (ie. encoder is part of display controller block, but hdmi_bridge or hypothetical dp_bridge/dsi_bridge, are a different block with (in some cases) their own irq, (in all cases) their own register space, etc. So the bridge/connector split worked pretty nicely there. I didn't look closely at why you have things split up this way, but if the reasons are similar then I'd suggest sti_bridge/sti_connector..

hmm, ok, so couple issues here..
first, either that 'if (connector)' above is pointless (because you never expect connector to be NULL) or you're going to crash deref'ing connector->type.
Also, what is the purpose of this switch, vs just having the connector specific implementation of connector->prepare() (which maybe should actually be in sti_bridge) do call right thing?
