The mhdp bridge can work without its HPD pin hooked up to the connector,
but the current bridge driver throws an error when hpd line is not
connected to the connector. For such cases, we need an indication for
no-hpd, using which we can bypass the hpd detection and instead use the
auxiliary channels connected to the DP connector to confirm the
connection.
So add no-hpd property to the bindings, to disable hpd when not
connected or unusable.
Your subject prefixes miss device specific part. You do not add no-hpd
to all bridges.
It's also not drm. It is a display directory.
Sorry messed the commit heading. Will fix it.
