[PATCH 0/9] cec improvements

[Hans Verkuil]

From: Hans Verkuil <hans.verkuil at cisco.com>

This patch series adds several helper functions to ease writing
drm or media CEC drivers.

It also adds support for the CEC_CAP_NEEDS_HPD capability which is
needed for hardware that turns off the CEC support if the hotplug
detect signal is low. Usually because the HPD is connected to some
'power' or 'active' pin of the CEC hardware.

One of those is the Odroid-U3, so add a 'needs-hpd' property that
tells the driver whether or not CEC is available without HPD.

Regards,

	Hans
