Subject: [PATCH mvebu-dt v2 4/6] ARM: dts: turris-omnia: add SFP node
Date: Sat, 14 Nov 2020 19:32:15 +0100 [thread overview]
Message-ID: <20201114183217.1352-5-kabel@kernel.org> (raw)
In-Reply-To: <20201114183217.1352-1-kabel@kernel.org>
Turris Omnia has a SFP cage that, together with WAN PHY is connected to
eth2 SerDes via a SerDes multiplexor. Describe the SFP cage, but leave
it disabled. Until phylink has support for such multiplexor we will
leave it to U-Boot to enable SFP and disable WAN PHY at boot time
depending on whether a SFP module is present.
Signed-off-by: Marek Behún <kabel@kernel.org>
Fixes: 26ca8b52d6e1 ("ARM: dts: add support for Turris Omnia")
