Date
From: Anson Huang <Anson.Huang@nxp.com> Sent: Wednesday, October 9, 2019 6:16 PM
> Use platform_get_irq_byname_optional() and platform_get_irq_optional()
> instead of platform_get_irq_byname() and platform_get_irq() for optional
> IRQs to avoid below error message during probe:
>
> [ 0.795803] fec 30be0000.ethernet: IRQ pps not found
> [ 0.800787] fec 30be0000.ethernet: IRQ index 3 not found
