Subject: Re: [PATCH] net: fec: fix enet_out clock handling

> Do you mean PHY switch also use the enet_out clock ?

Yes, the Marvell switches i've have connected to a Vybrid use enet_out
clock. There was a recent change to IMX pinctrl which broke the muxing
for ENET_OUT on Vydrid, which broke the probing of these switches. It
was no longer possible to mux the pin as ENET_OUT, and the switches
disappeared.
