ok so now priv->dp and priv->edp arrays are also in the picture here :)
Actually all these questions should have probably come when we were
figuring out how best to re-use eDP and DP driver.
Either way atleast, its good we are documenting all these questions on
this thread so that anyone can refer this to know what all was missed out :)
priv->dp is of type msm_dp. When re-using DP driver for eDP and since
struct msm_dp is the shared struct between dpu and the msm/dp, I get
your point of re-using MSM_DP_CONTROLLER_* as thats being use to index.
So MSM_DP_CONTROLLER_* is more of an index into the DP driver and not
really a hardware indexing scheme.
If we split into two arrays, we need more changes to dpu_encoder too.
Too instrusive a change at this point, even though probably correct.
But are you seeing more changes required even if we just change INTF_DP
to INTF_eDP for the eDP entries? What are the challenges there?

struct msm_dp is the useful abstraction already for drm/msm/dp.
Not INTF_DP.

Can you please elaborate why changing INTF_DP to INTF_eDP is more
trouble if we leave the MSM_DP_CONTROLLER_* intact?
