From 93a738894346d01687c8979bca129d7eaaf7d35f Mon Sep 17 00:00:00 2001 From: Bryan O'Donoghue Date: Tue, 19 Jul 2016 15:04:37 +0100 Subject: [PATCH] greybus: timesync: reduce initial startup time Currently we have a long initial delay when initiating the first operation to synchronize the FrameTime. That made sense during development of the feature since we did synchronization asynchronously and wanted to give some grace time for new Interfaces to be added before initiating a new synchronization. On the PM runtime resume path though we do a synchronous restoration of FrameTime and in this case waiting for 1 second before initiating the first operation is clearly wrong. This patch reduces the initial operation time bringing the synchronous call time down by 990 milliseconds.
