Some interfaces (WB, DSI Command Mode) need to be kicked off through a START Signal. This signal needs to be sent at the right time and requests in some cases to keep track of the pipeline status (eg: whether pipeline registers are flushed AND output WB buffers are ready, in case of WB interface).

msm8x16 would require a flush_hw_mask too, it should be 0x32a59 if I'm not wrong. Could you please add it for the next revision, or as a part of the 8x16 hw cfg patch?
