[PATCH v2 03/17] drm/msm/dpu: Move non-MDP_TOP INTF_INTR offsets out of hwio header
Posted by Marijn Suijten 2 years, 8 months ago 
These offsets do not fall under the MDP TOP block and do not fit the
comment right above.  Move them to dpu_hw_interrupts.c next to the
repsective MDP_INTF_x_OFF interrupt block offsets.

Even HIST_INTR_*** need to be moved then.

These are relative to MDP_SSPP_TOP0_OFF too just like
INTR(2)_{CLEAR,EN,STATUS} so I left them here.  Otherwise, *all* these
interrupt masks are probably best moved to dpu_hw_interrupts.c for
clarity, as that's also the only place they are used?

Let me know which way you prefer.
