From 6a097b0d054f1493ecf623dde83b26e6ec5a7c2d Mon Sep 17 00:00:00 2001 From: Jolly Shah Date: Wed, 14 Jun 2017 15:03:52 -0700 Subject: [PATCH] arm64: zynqmp: Reduced min-residency time for idle state node Changed min-residence to 10ms(was 100 ms) for cpu-sleep-0. Tried lower values 5ms and 8ms and it worked fine with Debug Off. But to accommodate PM Debug On case, 10 ms is required. With this change, low power idle state is into effect more frequently. Measured boot time with PM debugs On and Off. No change observed compared to 100ms value.
