Hi Archit,
Hi Stephane,

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?
Correct; thanks for pointing this out.
IMO, this value should be 0x4003ffff because the fields are actually
present in the register (even though the interfaces/pipes.etc. are not).
Anyway, these bits won't be accessed because the driver won't even allow
the usage of the corresponding resources.
Okay, that makes sense.
I will update in the v2 of "drm/msm/mdp5: Add hardware configuration for
msm8x16".
Thanks,
Stephane.
Thanks!
Archit
