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.
