   4 Subject: [PATCH] arm64: dts: mt7622: handle interrupts from MT7531 switch on
   5  BPI-R64
   6
   7 Since commit ba751e28d442 ("net: dsa: mt7530: add interrupt support")
   8 the mt7530 driver can act as an interrupt controller. Wire up irq line
   9 of the MT7531 switch on the BananaPi BPi-R64 board, so the status of
  10 the PHYs of the five 1000Base-T ports doesn't need to be polled any
  11 more.
