Hi Laurent,

Is this a property of the hardware, that is, are there multiple versions of this IP core covered by the same compatible string that support HDCP 1.4 only, DHCP 2.2 only or both ? Or is it a way to select what a given system will offer ?[]

MHDP hardware supports both HDCP 2.2 and 1.4. So, this is a way to select the version of HDCP, system wish to support.

Then I'm not sure this qualifies as a DT property, which should describe the system, not configure it. A way for userspace to configure this would be better.
