[PATCH 0/5] drm/omap: hdmi: improve hdmi4 CEC, add CEC for hdmi5

[Hans Verkuil]

This series improves the drm_bridge support for CEC by introducing two
new bridge ops in the first patch, and using those in the second patch.

This makes it possible to call cec_s_conn_info() and set
CEC_CAP_CONNECTOR_INFO for the CEC adapter, so userspace can associate
the CEC adapter with the corresponding DRM connector.

The third patch simplifies CEC physical address handling by using the
cec_s_phys_addr_from_edid helper function that didn't exist when this
code was originally written.

The fourth patch adds CEC support to the OMAP5 driver and the last
patch adds the missing cec clock to the dra7 and omap5 device tree.

Tested with a Pandaboard and a Beagle X15 board.

Regards,

	Hans
