Subject: [PATCH net-next v4 0/9] net: stmmac: add new features to xgmac

This series add below new features to xgmac:

correct RX COE parsing
add more feature parsing from hw cap
enlarge C22 ADDR and rx/tx channels
support parse safety ce/ue irq from DT
support per channel irq

Since v3:
 - collect Acked-by tag
 - remove patch which enlarges the max XGMAC C22 ADDR to 31 since it's
   merged
 - s/stmmac_request_irq_multi/stmmac_request_irq_multi_channel
 - update the dt-binding to refelct the optional per-channel irq:
     - use enum
     - add additionalItems and maxItems to fix the "interupt-names ..
       is too long"

Since v2:
 - check per channel irq by (res->rx_irq[0] > 0 && res->tx_irq[0] > 0)
   rather than (res->rx_irq[0] && res->tx_irq[0])
 - bypass if (irq <= 0) when request rx/tx irq

Since v1:
 - remove "_irq" suffix from safety irqs dt binding
 - remove "snps,per-channel-interrupt" dt binding, check the channel irq
   instead.
 - more renaming about "msi" to reflect per channel irq isn't MSI
   specific
