Subject: [PATCH 1/2] platform/chrome: cros_ec_typec: Skip port partner check in configure_mux()
Date: Fri, 5 Feb 2021 11:51:12 -0800 [thread overview]
Message-ID: <20210205195113.20277-2-rajmohan.mani@intel.com> (raw)
In-Reply-To: <20210205195113.20277-1-rajmohan.mani@intel.com>
For certain needs like updating the USB4 retimer firmware when no
device are connected, the Type-C ports require mux configuration,
to be able to communicate with the retimer. So removed the above
check to allow for mux configuration of Type-C ports, to enable
retimer communication.
