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.
