Subject: [PATCH 0/8] usb: typec: ucsi: yoga-c630: enable DisplayPort
 support

On Lenovo Yoga C630 laptop the EC implements UCSI support. However in
order to properly handle DisplayPort AltMode events it requires
additional support. Implement several workarounds, fixing issues with
AltMode UCSI commands and also handle out-of-bound DisplayPort hotplug
events.
