dsa: lan9303: Move to PHYLINK
This patch series moves the lan9303 driver to use the phylink
api away from phylib.
Migrating to phylink means removing the .adjust_link api. The
functionality from the adjust_link is moved to the phylink_mac_link_up
api. The code being removed only affected the cpu port. The other
ports on the LAN9303 do not need anything from the phylink_mac_link_up
api.
Patches:
0001 - Whitespace only change aligning the dsa_switch_ops members.
No code changes.
0002 - Moves the Turbo bit initialization out of the adjust_link api and
places it in a driver initialization execution path. It only needs
to be initialized once, it is never changed, and it is not a
per-port flag.
0003 - Adds exception handling logic in the extremely unlikely event that
the read of the device fails.
0004 - Performance optimization that skips a slow register write if there
is no need to perform it.
0005 - Change the way we identify the xMII port as phydev will be NULL
when this logic is moved into phylink_mac_link_up.
0006 - Removes adjust_link and begins using the phylink dsa_switch_ops
apis.
0007 - Adds XMII port flow control settings in the phylink_mac_link_up()
api while cleaning up the ANEG / speed / duplex implementation.
---
v6->v7:
- Moved the initialization of the Turbo bit into lan9303_setup().
- Added a macro for determining is a port is an XMII port.
- Added setting the XMII flow control in the phylink_mac_link_up() API.
- removed unnecessary error handling and cleaned up the code flow in
phylink_mac_link_up().
v5->v6:
- Moved to using port number to identify xMII port for the LAN9303.
v4->v5:
- Created prep patches to better show how things migrate.
- cleaned up comments.
v3->v4:
- Addressed whitespace issues as a separate patch.
- Removed port_max_mtu api patch as it is unrelated to phylink migration.
- Reworked the implementation to preserve the adjust_link functionality
by including it in the phylink_mac_link_up api.
v2->v3:
Added back in disabling Turbo Mode on the CPU MII interface.
Removed the unnecessary clearing of the phy supported interfaces.
v1->v2:
corrected the reported mtu size, removing ETH_HLEN and ETH_FCS_LEN

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.
