Subject: [PATCH resend 07/12] typec: tcpm: add starting value for drp toggling
Date: Tue, 26 Sep 2017 12:05:18 +0800 [thread overview]
Message-ID: <1506398723-19359-8-git-send-email-jun.li@nxp.com> (raw)
In-Reply-To: <1506398723-19359-1-git-send-email-jun.li-3arQi8VN3Tc@public.gmane.org>
As DRP port autonomously toggles the Rp/Rd need a start value to
begin with, so add one parameter for it in tcpm_start_drp_toggling.
