6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxx>
[ Upstream commit ad6556fb45d4ab91ad786a2025cbe2b0f2e6cf77 ]
The idle state entry/exit/residency times differ from what shipped on
production devices, mostly being overly optimistic in entry times and
overly pessimistic in minimal residency times. Align them with
downstream sources.
