[PATCH 3/5] drm/i915: DDI naming standards cleanup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Paulo Zanoni <paulo.r.zanoni at intel.com>

A big part of the Haswell display code is called intel_ddi_something
while a small part of it is called haswell_something. Being consistent
with the naming standards is a nice thing, so IMHO we should only use
one of the naming standards for everything.

So instead of converting everything to haswell_something I converted
to ddi_something, which seems more appropriate IMHO. Now our code
looks a little bit more consistent.

The next step is to move everything to intel_ddi.c.
