[V3,2/2] arm: dts: am3517-evm: Enable Ethernet PHY Interrupt

Commit Message

Adam Ford Oct. 5, 2023, 12:04 a.m. UTC

The Ethernet PHY interrupt pin is routed to GPIO_58.  Create a
PHY node to configure this GPIO for the interrupt to avoid polling.

V3:  Fix issue where V2 wasn't properly properly commit-ammended, so V2 patch didn't properly generate

V2:  Attempted (but failed) to fix ethernet-phy-pins naming

Thanks applying both into omap-for-v6.7/dt.
