Subject[PATCH v2 08/24] net: stmmac: Add {axi,mtl-rx,mtl-tx}-config sub-nodes support
Date
Currently the "snps,axi-config", "snps,mtl-rx-config" and
"snps,mtl-tx-config" DT node properties are marked as deprecated when
being defined as a phandle reference to a node with parameters. The new
way of defining the DW MAC interfaces config is to add sub-nodes to the DW
MAC device DT node with vendor-prefixless names. Make sure the STMMAC
driver supports them.

Signed-off-by: Serge Semin <Sergey.Semin@baikalelectronics.ru>

Changelog v2:
- Discard "snps" vendor-prefix from the new AXI/MTL Tx/Rx config
sub-nodes.
