From 6d5c898798aca634f493cabd2e7a47407ee5e95d Mon Sep 17 00:00:00 2001 From: "Machani, Yaniv" Date: Thu, 30 Jul 2015 22:38:19 +0300 Subject: [PATCH] wlcore/wl18xx : add time sync event handling Added support for a new time sync event the event data contains the WiLink TSF value. To trigger the event, a HW modification is required, so as a supporting firmware binary.
