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 v2:
- connector_attach can now return an error. If an error is returned then connector_detach is called in reverse order to clean up any previous connector_attach calls.
- connector_attach in hdmi4 and hdmi5 now return 0.
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.
