2016-08-22[media] cec-edid: check for IEEE identifierHans Verkuil1-1/+4
The cec_get_edid_spa_location() function did not verify that the IEEE identifier in the Vendor Specific Data Block matched the HDMI-LLC identifier. This could result in the wrong VSDB block being returned. For example, for HDMI 2.0 EDIDs there is also a HDMI Forum VSDB. So check the IEEE identifier as well.

2016-06-28[media] cec-edid: add module for EDID CEC helper functionsHans Verkuil1-0/+168
The cec-edid module contains helper functions to find and manipulate the CEC physical address inside an EDID. Even if the CEC support itself is disabled, drivers will still need these functions. Which is the reason this is module is separate from the upcoming CEC framework. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
