Subject: [RFC PATCH net-next 1/8] dt-bindings: net: Add support for AM65x SR1.0 in ICSSG
Silicon Revision 1.0 of the AM65x came with a slightly different ICSSG
support: Only 2 PRUs per slice are available and instead 2 additional
DMA channels are used for management purposes. We have no restrictions
on specified PRUs, but the DMA channels need to be adjusted.
