Subject: [PATCH net-next v3 2/2] ARM: dts: aspeed: elbert: Enable mac3 controller
Date: Tue,  6 Sep 2022 22:44:53 -0700	[thread overview]
Message-ID: <20220907054453.20016-3-rentao.bupt@gmail.com> (raw)
In-Reply-To: <20220907054453.20016-1-rentao.bupt@gmail.com>

From: Tao Ren <rentao.bupt@gmail.com>

Enable mac3 controller in Elbert dts: Elbert MAC3 is connected to the
BCM53134P onboard switch's IMP_RGMII port directly (fixed link, no PHY
between BMC MAC and BCM53134P).

Note: BMC's mdio0 controller is connected to BCM53134P's MDIO interface,
and the MDIO channel will be enabled later, when BCM53134 is added to
"bcm53xx" DSA driver.

Signed-off-by: Tao Ren <rentao.bupt@gmail.com>
