Subject: [PATCH 3/4] arm: dts: gr-peach: Add ETHER pin group
Date: Thu, 24 Aug 2017 10:48:42 +0200	[thread overview]
Message-ID: <1503564523-31899-4-git-send-email-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <1503564523-31899-1-git-send-email-jacopo+renesas-AW8dsiIh9cEdnm+yROfE0A@public.gmane.org>

Add pin configuration subnode for ETHER pin group.
The interface can be configured and probed, but no traffic can be
transmitted or received.

Signed-off-by: Jacopo Mondi <jacopo+renesas-AW8dsiIh9cEdnm+yROfE0A@public.gmane.org>

---
When in u-boot console I can ping a connected host, after the
system has booted I can configure an ip address on the interface but
cannot exchange any traffic.
I have compared the pin configuration procedure with the u-boot
implemented one and some sketches from mbed operating system libraries,
the configured pins are correct and registers values seems to match.
Not sure if this patch should be sent for inclusion but sending it out
anyway for you to judge this.

Thanks
