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 the cec clock to ti,omap5-dss.txt.

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

Tested with a Pandaboard and a Beagle X15 board.

Regards,

	Hans

Changes since v1:

- as per suggestion from Laurent, changed cec_init/exit to
  connector_attach/_detach which are just called for all
  bridges. The DRM_BRIDGE_OP_CEC was dropped.

- added patch to add the cec clock to ti,omap5-dss.txt

- swapped the order of the last two patches

- incorporated Tomi's suggestions for the hdmi5 CEC support.
