According to the TODO, In sw_bus_master_add, bus->multi_link is to be populated with properties from FW node props. Make this happen by creating a new fwnode_handle flag FWNODE_FLAG_MULTI_LINKED and use the flag to store the multi_link value from intel_link_startup. Use this flag to initialize bus->multi_link.
...
/* * Initialize multi_link flag - * TODO: populate this flag by reading property from FW node */ - bus->multi_link = false; + bus->multi_link = (fwnode->flags & FWNODE_FLAG_MULTI_LINKED) + == FWNODE_FLAG_MULTI_LINKED;
NAK (as far as I understood the context of the comment and the change itself).
These flags are for devlink, we do not mix FW properties with those internal flags anyhow. The comment suggests that this should be az property. Also commit message doesn't explain the relation to devlink.
That is a good information to know. Thanks.
I shall try to find out if I can somehow get multi_link's value from fwnode in any other way and look into devlink in the process.
If you have any suggestions regarding this TODO, please let me know.
The suggestion is to remove the TODO and leave the code as is: the capabilities enabled for multi-link are required as part of the programming sequences, even when a stream uses a single link we still use the syncArm/syncGo sequences.
Please don't change this.
Thanks for the suggestion! I shall send a patch with the TODO removed, leaving the code as is.
