Subject: [PATCH v2 0/5] usb: typec: ucsi: glink: rework orientation
 handling

Simplify the way the UCSI GLINK driver handles cable orientation. Make
the UCSI core responsible for pinging the driver to get cable status.
Use typec-port API instead of calling typec_switch_set() directly.
Also make the orientation status available via the sysfs.
