Linux Kernel Mentee: Remove Legacy Power Management.
The purpose of this patch series is to remove legacy power management callbacks

The callbacks performing suspend() and resume() operations are still calling

themselves, which is not recommended.
The conversion requires the removal of the those function calls and change the
callback definition accordingly and make use of dev_pm_ops structure.

To ensure that the octeon MDIO driver has been loaded, the Cavium
ethernet drivers reference a dummy symbol in the MDIO driver. This
forces it to be loaded first. And this symbol has not been cleanly
implemented, resulting in warnings when build W=1 C=1.
Since device tree is being used, and a phandle points to the PHY on
the MDIO bus, we can make use of deferred probing. If the PHY fails to
connect, it should be because the MDIO bus driver has not loaded
yet. Return -EPROBE_DEFER so it will be tried again later.
Additionally, add a MODULE_SOFTDEP() to give user space a hint as to
what order it should load the modules.

geneve: move all configuration under struct geneve_config
This patch adds a new structure geneve_config and moves the per-device
configuration attributes to it, like we already have in VXLAN with
struct vxlan_config. This ends up being pretty invasive since those
attributes are used everywhere.
This allows us to clean up the argument lists for geneve_configure (4
arguments instead of 8) and geneve_nl2info (5 instead of 9).
This also reduces the copy-paste of code setting those attributes
between geneve_configure and geneve_changelink to a single memcpy,
which would have avoided the bug fixed in commit 56c09de347e4 ("geneve: allow changing DF behavior after creation").

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states. And they use PCI
helper functions to do it.
After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.
In this driver:
gem_suspend() calls gem_do_stop() which in turn invokes
pci_disable_device(). As the PCI helper function is not called at the
end/start of the function body, breaking the function in two parts
may change its behavior.
The only other function invoking gem_do_stop() is gem_close(). Hence,
gem_close() and gem_suspend() can do the required end steps on their own.
The same case is with gem_resume(). Both gem_resume() and gem_open()
invoke gem_do_start(). Again, make the caller functions do the required
steps on their own.
Compile-tested only.

Patches 1, 3, 4 and 5 are cleanup, patch 2 is adding a new feature and

(mac_link_up).
Changes since v2:
- Replaced "PHYLINK" with "phylink".
- Rewrote commit message of patch 5/6.
Changes since v1:
- Now using phy_clear_bits and phy_set_bits instead of plain writes to

net: dsa: felix: use resolved link config in mac_link_up()
Phylink now requires that parameters established through
auto-negotiation be written into the MAC at the time of the
mac_link_up() callback. In the case of felix, that means taking the port
out of reset, setting the correct timers for PAUSE frames, and
enabling/disabling TX flow control.
This patch also splits the inband and noinband configuration of the
vsc9959 PCS (currently found in a function called "init") into 2
different functions, which have a nomenclature closer to phylink:
"config", for inband setup, and "link_up", for noinband (forced) setup.
This is necessary as a preparation step for giving up control of the PCS
to phylink, which will be done in further patch series.

Phylink uses the .mac_an_restart method to offer the user an
implementation of the "ethtool -r" behavior, when the media-side auto
negotiation can be restarted by the local MAC PCS. This is the case for
fiber modes 1000Base-X and 2500Base-X (IEEE clause 37) that don't have
an Ethernet PHY connected locally, and the media is connected to the MAC
PCS directly.
On the other hand, the Cisco SGMII and USXGMII standards also have an
auto negotiation mechanism based on IEEE 802.3 clause 37 (their
respective specs require a MAC PCS and a PHY PCS to implement the same
state machine, which is described in IEEE 802.3 "Auto-Negotiation Figure
37-6"), so the ability to restart auto-negotiation is intrinsically
symmetrical (the MAC PCS can do it too).
However, it appears that not all SGMII/USXGMII PHYs have logic to
restart the MDI-side auto-negotiation process when they detect a
transition of the SGMII link from data mode to configuration mode.
Some do (VSC8234) and some don't (AR8033, MV88E1111). IEEE and/or Cisco
specification wordings to not help to prove whether propagating the "AN
restart" event from MII side ("mr_restart_an") to MDI side
("mr_restart_negotiation") is required behavior - neither of them
specifies any mandatory interaction between the clause 37 AN state
machine from Figure 37-6 and the clause 28 AN state machine from Figure
28-18.
Therefore, even if a certain behavior could be proven as being required,
real-life SGMII/USXGMII PHYs are inconsistent enough that a clause 37 AN
restart cannot be used by phylink to reliably trigger a media-side
renegotiation, when the user requests it via ethtool.
The only remaining use that the .mac_an_restart callback might possibly
have, given what we know now, is to implement some silicon quirks, but
so far that has proven to not be necessary.
So remove this code for now, since it never gets called and we don't
foresee any circumstance in which it might be, either.

OCELOT_SPEED_10 or OCELOT_SPEED_100, it'll start transmitting PAUSE

it at OCELOT_SPEED_1000 afterwards.
This patch fixes a bug that luckily did not have any functional impact.
We were writing 10, 100, 1000 etc into this 2-bit field in
