From e6227ee64782e1cda88a70512ac2b0ae8fda2203 Mon Sep 17 00:00:00 2001 From: Bryan O'Donoghue Date: Thu, 15 Oct 2015 16:10:44 +0100 Subject: [PATCH] greybus: loopback: add tracker variables to hold firmware timestamps This patch adds tracker variables to hold the incoming firmware derived timestamps where apbridge_latency_ts will contain the APBridge's view of the UniPro turn-around time and gpbridge_latency_ts will contain the GPBridge's view of it's own internal latency. Both values are reported in microseconds.
