[OpenWrt-Devel] ath79: seting GPIO registers to specific values via DTS?

[Roger Pueyo Centelles | Guifi.net]

Hi Seb,

You nailed it! :-)

I was missing the ' "pinctrl-names = "default"; ' line. I must have
removed it from the .dts file I used as the source for mine at some
point. Then I just sorted the pinctrl-0/1 issue, which I had already
tried in any possible combination.

After fixing this, I have detected another issue that had passed
unnoticed to me before. The eth1 interface always appears as UP (i.e.,
having link), even if I unplug the cable.

According to the datasheet, GMAC1 (eth1 here) is internally connected to
the integrated switch. The "swconfig dev switch0 show" command gives:

Port 0:
    enable_mirror_rx: 0
    enable_mirror_tx: 0
    pvid: 0
    link: port:0 link:up speed:1000baseT full-duplex txflow rxflow
Port 1:
    enable_mirror_rx: 0
    enable_mirror_tx: 0
    pvid: 1
    link: port:1 link:up speed:100baseT full-duplex auto

How should I manage this?

Thank you very much for your support.

Best,

Roger
