Subject: [PATCH 11/12] staging: typec: tcpci: Only touch target bit when enable vconn
Date: Tue, 26 Sep 2017 08:45:26 +0800	[thread overview]
Message-ID: <1506386727-16370-12-git-send-email-jun.li@nxp.com> (raw)
In-Reply-To: <1506386727-16370-1-git-send-email-jun.li-3arQi8VN3Tc@public.gmane.org>

We need regmap_update_bits to avoid touch any other bits when
enable or disable vconn.
