-Subject: [PATCH] net: bgmac: support Ethernet core on BCM53573 SoCs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and can
-be found in two packages (versions): BCM53573 and BCM47189. It shares
-some code with the Northstar family, but also requires some new quirks.
-
-First of all there can be up to 2 Ethernet cores on this SoC. If that is
-the case, they are connected to two different switch ports allowing some
-more complex/optimized setups. It seems the second unit doesn't come
-fully configured and requires some IRQ quirk.
-
-Other than that only the first core is connected to the PHY. For the
-second one we have to register fixed PHY (similarly to the Northstar),
-otherwise generic PHY driver would get some invalid info.
-
-This has been successfully tested on Tenda AC9 (BCM47189B0).
