The usage is the same as previous sysfs node as the input parameters are not changed. There are 3 different flags could be passed in: SET_ENABLE, ENABLE, and CONNECT.

At this point of time, the EDID data of the sink will not be available and the bpp of sink is set as 18 by default. If a sink is connected first time on boot-up with 480p resolution, the panel information doesn't get updated since current VIC and new VIC are the same. If the panel bpp specified in EDID is not 18, display might fail to come up. Handle this issue by updating the panel info every time when a DP connection is established independent of whether VIC changed or not.
