net: dsa: b53: Add support for Broadcom RoboSwitch This patch adds support for Broadcom's BCM53xx switch family, also known as RoboSwitch. Some of these switches are ubiquituous, found in home routers, Wi-Fi routers, DSL and cable modem gateways and other networking related products. This drivers adds the library driver (b53_common.c) as well as a few bus glue drivers for MDIO, SPI, Switch Register Access Block (SRAB) and memory-mapped I/O into a SoC's address space (Broadcom BCM63xx/33xx). Basic operations are supported to bring the Layer 1/2 up and running, but not much more at this point, subsequent patches add the remaining features.

Since the Cygnus was added with the BCM58XX device id and the BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is broken, due to the incorrect brcm tag location. Add a new b53 device id (BCM583XX) for Cygnus family to fix the issue. Add the new device id to the BCM58XX family as Cygnus is similar to the BCM58XX in most other functionalities.

net: dsa: b53: Fix for brcm tag issue in Cygnus SoC In the Broadcom Cygnus SoC, the brcm tag needs to be inserted in between the mac address and the ether type (should use 'DSA_PROTO_TAG_BRCM') for the packets sent to the internal b53 switch. Since the Cygnus was added with the BCM58XX device id and the BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is broken, due to the incorrect brcm tag location. Add a new b53 device id (BCM583XX) for Cygnus family to fix the issue. Add the new device id to the BCM58XX family as Cygnus is similar to the BCM58XX in most other functionalities.

net: dsa: Remove prepare phase for FDB The prepare phase for FDB add is unneeded because most of DSA devices can have failures during bus transactions (SPI, I2C, etc.), thus, the prepare phase cannot guarantee success of the commit stage. The support for learning FDB through notification chain, which will be introduced in the following patches, will provide the ability to notify back the bridge about successful offload.

net: dsa: b53: Add support for Broadcom RoboSwitch This patch adds support for Broadcom's BCM53xx switch family, also known as RoboSwitch. Some of these switches are ubiquituous, found in home routers, Wi-Fi routers, DSL and cable modem gateways and other networking related products. This drivers adds the library driver (b53_common.c) as well as a few bus glue drivers for MDIO, SPI, Switch Register Access Block (SRAB) and memory-mapped I/O into a SoC's address space (Broadcom BCM63xx/33xx). Basic operations are supported to bring the Layer 1/2 up and running, but not much more at this point, subsequent patches add the remaining features.
