Hi all, This patch series adds support for the Broadcom BCM53xx series aka RoboSwitches.
This driver is largely based on Jonas Gorski's b53 driver for OpenWrt which can be found here: https://dev.openwrt.org/browser/trunk/target/linux/generic/files/drivers/net/phy/b53 a few bug fixes and DSA-ifycation later, here is what we got. This has been successfully tested in the following configurations: - Broadcom BCM53011 using the SRAB bus layer with 4 ports LAN, 1 port WAN - A Broadcom BCM7445 device with an internal Starfighter 2 switch (bcm_sf2.c) and a Broadcom BCM53125 hanging off one of its ports connected via MDIO, creating two trees hanging off each other, and this works! - A Broadcom BCM53125 MDIO connected to a Lamobo/Bananapi R1 board using the STMMAC MDIO driver For now, we do not enable Broadcom tags, because there are different generations of switches being supported which have different tag formats, but the plan is to enable them later on. Support for different HW features will be added later: EEE, Compact Field Processor (TCAM) once this initial cut gets accepted. Testing and bug reports welcome!
