Neil Armstrong 7a78c1e116 media: cec-notifier: Get notifier by device and connector name
In non device-tree world, we can need to get the notifier by the driver
name directly and eventually defer probe if not yet created.

This patch adds a variant of the get function by using the device name
instead and will not create a notifier if not yet created.

But the i915 driver exposes at least 2 HDMI connectors, this patch also
adds the possibility to add a connector name tied to the notifier device
to form a tuple and associate different CEC controllers for each HDMI
connectors.

Hans Verkuil fc1ff45a07 media: cec-notifier: small improvements
Allow calling cec_notifier_set_phys_addr and
cec_notifier_set_phys_addr_from_edid with a NULL notifier, in which
case these functions do nothing.

Add a cec_notifier_phys_addr_invalidate helper function (the notifier
equivalent of cec_phys_addr_invalidate).

These changes simplify drm CEC driver support.

Hans Verkuil ee7e987133 [media] cec.h: merge cec-edid.h into cec.h
Drop the separate cec-edid.h header and merge it into cec.h.

There was really no need to have a separate header for this.

Hans Verkuil 56a263aaa0 [media] cec: Kconfig cleanup
The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.

Move those sources to media/cec as well.

The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.

Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).

Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.

CEC drivers should now depend on CEC_CORE.

CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.

The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.
