[PATCH 13/19] drm/i915: don't get/put PC8 when getting/putting power wells

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

 



From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx>

Because we already get/put runtime PM every time we get/put any power
domain, and now PC8 and runtime PM are the same thing.

With this, we can also now kill the hsw_{en,dis}able_package_c8
functions.
