The Marvell 88E6393X device is a single-chip integration of a 11-port Ethernet switch with eight integrated Gigabit Ethernet (GbE) transceivers and three 10-Gigabit interfaces. This patch adds functionalities specific to mv88e6393x family (88E6393X, 88E6193X and 88E6191X). The main differences between previous devices and this one are: - port 0 can be a SERDES port - all SERDESes are one-lane, eg. no XAUI nor RXAUI - on the other hand the SERDESes can do USXGMII, 10GBASER and 5GBASER (on 6191X only one SERDES is capable of more than 1g; USXGMII is not yet supported with this change) - Port Policy CTL register is changed to Port Policy MGMT CTL register, via which several more registers can be accessed indirectly - egress monitor port is configured differently - ingress monitor/CPU/mirror ports are configured differently and can be configured per port (ie. each port can have different ingress monitor port, for example) - port speed AltBit works differently than previously - PHY registers can be also accessed via MDIO address 0x18 and 0x19 (on previous devices they could be accessed only via Global 2 offsets 0x18 and 0x19, which means two indirections; this feature is not yet leveraged with thiis commit) Co-developed-by: Ashkan Boldaji <ashkan.boldaji@digi.com> Signed-off-by: Ashkan Boldaji <ashkan.boldaji@digi.com> Signed-off-by: Pavana Sharma <pavana.sharma@digi.com> Co-developed-by: Marek Behún <kabel@kernel.org> Signed-off-by: Marek Behún <kabel@kernel.org> Signed-off-by: David S.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
