Add iterators for EDID blocks and CEA data blocks, to iterate through
all data blocks across all CEA extensions and CTA blocks in DisplayID
data blocks. Fix all code assuming only one CEA extension. Fix code
assuming CTA blocks contain everything that CEA extensions do. Sprinkle
a bunch of cleanups on top.
This is completely UNTESTED, didn't even smoke test it. It builds. ;)
This superseeds parts of [1] and [2].
BR,
Jani.

Jani Nikula (19):
drm/edid: add drm_edid_extension_block_count() and drm_edid_size()
drm: use drm_edid_extension_block_count() and drm_edid_size()
drm/edid: clean up CEA data block tag definitions
drm/edid: add iterator for EDID base and extension blocks
drm/edid: add iterator for CEA data blocks
drm/edid: clean up cea_db_is_*() functions

It's just a number, so could be 'int' IMO.

* [RFC 06/19] drm/edid: clean up cea_db_is_*() functions

Abstract helpers for matching vendor data blocks and extended tags, and
use them to simplify all the cea_db_is_*() functions.
Take void pointer as parameter to allow transitional use for both u8 *
and struct cea_db *.

Abstract helpers for matching vendor data blocks and extended tags, and
use them to simplify all the cea_db_is_*() functions.
Take void pointer as parameter to allow transitional use for both u8 *
and struct cea_db *.

I guess that's something I've picked up from Python, makes the
subsequent lines align nicely. Otherwise it's less pretty.

Only chose int because the oui() function returns an int; maybe that
should eventually be turned into unsigned int.

Use the cea db iterator for speaker allocation. We'll still stop at the
first speaker data block, but not at the first CEA extension if that
doesn't have the info.

This stuff should probably be converted over to the drm_edid_to_eld()
approach which looks up all the SADs from the whole EDID. But that's

Iterate through all CEA data blocks across all CEA extensions and
DisplayID data blocks. This may gather more data than before, and if
there's duplicated data, some is overwritten by whichever comes last.

Iterate through all CEA data blocks across all CEA extensions and
DisplayID data blocks. This may gather more data than before, and if
there's duplicated data, some is overwritten by whichever comes last.

The CTA data block in DisplayID does not have the bits from byte 3 that
a CEA extension has. Only look for them in CEA extensions, but also look
for them in all CEA extensions.

The CTA data block in DisplayID does not have the bits from byte 3 that
a CEA extension has. Only look for them in CEA extensions, but also look
for them in all CEA extensions.
The DisplayID CTA data block version does not seem to match the CEA
revision either. Ignore it for the purpose of CEA revision.

The DisplayID CTA data block version does not necessarily match the CEA
revision. Simplify by postponing drm_edid_to_eld() slightly, and reusing
the CEA revision extracted by drm_parse_cea_ext().
By not bailing out early in drm_edid_to_eld() we may end up filling
meaningless data to the ELD. However, the main decision for audio is not
the ELD, but rather drm_detect_monitor_audio() called by drivers.
(Arguably a future cleanup could do that in drm_add_edid_modes() and
cache the result in the connector.)

Convert drm_find_cea_extension() to a predicate function to check if the
EDID has a CEA extension or a DisplayID CTA data block. This is mainly
to avoid adding new users that only find the first CEA extension.

I'm thinking we could just do
if (modes)
modes += add_alternate_cea_modes(...);
at the end of add_cea_modes().
Or perhaps
if (found)
modes += add_alternate_cea_modes(...);
if we think that adding the alternate modes would be apporpriate
even when add_cea_modes() didn't add anything. Not sure.
Yes, that would still introduce a sligth change in behaviour
in case we have a CEA ext block/DisplayID CTA block without
any of the video/hdmi/y420vdb blocks, but that edge case
doesn't feel like a deal-breaker to me.

I'm thinking we could just do
if (modes)
modes += add_alternate_cea_modes(...);
at the end of add_cea_modes().
Or perhaps
if (found)
modes += add_alternate_cea_modes(...);
if we think that adding the alternate modes would be apporpriate
even when add_cea_modes() didn't add anything. Not sure.
Yes, that would still introduce a sligth change in behaviour
in case we have a CEA ext block/DisplayID CTA block without
any of the video/hdmi/y420vdb blocks, but that edge case
doesn't feel like a deal-breaker to me.
