Subject: [PATCH 0/2] Program Deep PKG_C_LATENCY register
Date: Thu,  1 Feb 2024 14:21:57 +0530	[thread overview]
Message-ID: <20240201085158.1000285-1-suraj.kandpal@intel.com> (raw)

The change needed here is to read the latency from the punit and write
it onto the display register PKGC_LATENCY, so that the DE_WAKE is
asserted at latency us before window2 to bring memory up for DSBs
Hw is also responsible to block from entering to deep PKGC until frame
start.
