From 490d43491e9542a73c5e7481c5dfa2a144ad2142 Mon Sep 17 00:00:00 2001 From: Sultan Alsawaf Date: Fri, 5 Feb 2021 21:44:57 +0300 Subject: [PATCH] defconfig: Enable devfreq boosting Boost the DDR bus for 58 ms when requested in order to improve jitter. The 3879 frequency step was determined empirically to be the minimum needed to sustain acceptably low jitter in UIBench.
