[v13,2/7] phy: Add HDMI configuration options
Commit Message
Allow HDMI PHYs to be configured through the generic
functions through a custom structure added to the generic union.
The parameters added here are based on HDMI PHY
implementation practices. The current set of parameters
should cover the potential users.
