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