Subject: [Intel-gfx] [RFC v2] drm/i915: lpsp with hdmi/dp outputs
Date: Fri, 30 Apr 2021 17:23:55 +0530 [thread overview]
Message-ID: <20210430115355.30611-1-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20200601101516.21018-1-anshuman.gupta@intel.com>
DG1 and DISPLAY_VER=13 onwards Audio MMIO/VERBS lies in PG0 power
well. So in order to detect audio capable DP/HDMI output it doesn't
require to enable PG3 power well on DG1 and PG2 on DISPLAY_VER=13
pltform. It will save the power when DP/HDMI outputs used as
lpsp configuration.
