[PATCH net-next 16/16] dt-bindings: net: dwmac: Add MTL Tx queue CBS-algo props dependencies

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently the CBS algorithm specific properties could be used
unconditionally in the MTL Tx queue sub-nodes. It's definitely wrong from
the correct Tx queue description point of view. Let's fix that in a way so
the "snps,send_slope", "snps,idle_slope", "snps,high_credit" and
"snps,low_credit" properties would be allowed only if the CBS TC algorithm
is enabled for the MTL Tx queue.
