Currently the interconnect framework provides the xlate() callback for
mapping the endpoints from phandle arguments in DT. This is implemented
by the provider drivers. But the endpoints (or the path between the
endpoints) might have an additional attributes, which should be parsed
and populated. During previous discussions [1], it was suggested that
adding more and more DT properties will not scale very well. So instead
of adding DT properties, such data should be put into the 'interconnects'
arguments.
This patchset is introducing a new xlate_extended() callback, which
would allow the interconnect provider drivers to parse additional data
(such as path tags) and allow the framework to make use of them.
Thanks to Sibi for the preliminary feedback and testing this patchset
on the sc7180 platform.
The patchset is based on linux-next (next-20200903).
Changelog:
v3:
* Rebase and update both dts patches as Doug reported that i missed to
update the cells for the GPU and also other stuff changed in DT recently.
* Pick Rob's Reviewed-by
v2: http://lore.kernel.org/r/[email protected]
* Add a patch to update the DT documentation, which i missed initially.
* Minor changes in commit text of patch 1/7. (Sibi)
* Remove a useless null check in patch 4/7. (Sibi)
* Print a warning if the number of DT args is higher than what we expect
in patch 3/7. (Matthias)
* Pick Reviewed-by/Tested-by tags.
* TODO: Replace tag IDs with macros in patches 5/7 and 7/7 when [2] lands.

Use the qcom_icc_xlate_extended() in order to parse tags, that are
specified as an additional arguments to the path endpoints in DT.

Currently there is the xlate() callback, which is used by providers for
mapping the nodes from phandle arguments. That's fine for simple mappings,
but the phandle arguments could contain an additional data, such as tag
information. Let's create another callback xlate_extended() for the cases
where providers want also populate the path tag data.

Increase the number of interconnect-cells, as now we can include
the tag information. The consumers can specify the path tag as an
additional argument to the endpoints.

Let's document that we now support specifying path tag information in the
arg cells of the 'interconnects' DT property. This information would be
populated when the xlate_extended() callback is used.
Specifying the tag in DT will allow the interconnect framework to do the
aggregation based on the tag automatically. The users can still use the
icc_set_tag() API if/when needed.

additional argument to the endpoints.
