Subject: [v3,09/12] typec: tcpm: add starting value for drp toggling
Date: Tue, 13 Mar 2018 17:34:35 +0800 [thread overview]
Message-ID: <1520933678-10535-10-git-send-email-jun.li@nxp.com> (raw)
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.
