====================
DSA Mavell drivers refactoring and cleanup
v1->v2:
* Add missing signed-of-by: For patches authored by Guenter Roeck.
* Add Reviewed by from Guenter Roack to patch #5.
This is a collection of patches again net-next from today containing
refactoring and consolidate of code, cleanups and using #define's to
replace register numbers.
Patch #1 Swaps the 6131 driver to use the consolidated setup code.
Patch #2 Moves the Switch IDs used during probe into a central
location. We need these later so that we can differentiate
the different features the devices have.
Patch #3 Makes the 6131 driver set the number of ports in the private
state structure. It then uses this, rather than hard coded
maximum number of ports.
Patch #4 Similar to Patch #3, but for the 6123_61_65 driver.
Patch #5 Similar to Patch #3, and #4, but for all the remaining
drivers. This greatly increases the similarity of the code
between drivers, allow further patches to consolidate the
duplicated code.
Patch #6 Consolidate the switch reset code, which has two minor
variants. Removes around 35 lines per driver.
Patch #7 Moves phy page access functions out of the 6352 driver into
the shared code. Currently only the 6352 driver uses this,
but it is likely other devices will come along wanting this
functionality.
Patch #8 Consolidates the code used to access phy registers. Removes
around 40 lines of code per driver.
Patch #9 Fixes missing mutex locking in the EEE code, and refactors
the code a bit to make it more understandable with respect to
locks.
Patch #10 Consolidates reading statistics. This is very similar code
for all devices, but the number of available statistics
differ, which can be determined from the product ID. Removes
around 65 lines per driver.
Patch #11 Add #defines for registers, and bits within the
registers. For the moment, this is limited to the shared
code. The individual drivers will be converted once the
remaining duplicated code is consolidated
Patch #12 Fix broken statistic counters on the 6172. The 6352 family
requires the port number is poked into a different set of
bits in the register compared to other devices.
Many thanks to Guenter Roeck for repeatedly reviewing the patches and
testing them on his hardware.

The statistic counters for the mv88e6172 never worked. This device is
a member of the 6352 family of chips, which has a slightly different
layout of the register used for capturing statistics. Add support for
detecting this family and poking the port in the right place in the
register.

This allows drivers to request per-vif and per-sta-tid queues from which
they can pull frames. This makes it easier to keep the hardware queues
short, and to improve fairness between clients and vifs.
The task of scheduling packet transmission is left up to the driver -
queueing is controlled by mac80211. Drivers can only dequeue packets by
calling ieee80211_tx_dequeue. This makes it possible to add active queue
management later without changing drivers using this code.
This can also be used as a starting point to implement A-MSDU
aggregation in a way that does not add artificially induced latency.

Currently, MoCA fixed PHYs are always in link-up state, regardless of
whether the link is actually up or not.
Add code to properly detect MoCA link state changes and to reflect the
new state in MoCA fixed PHY. Only GENET V3 and V4 MACs are capable of
detecting MoCA link state changes.
The code works as follows:
1. GENET MAC detects MoCA link state change and issues UMAC_IRQ_LINK_UP
or UMAC_IRQ_LINK_DOWN interrupt.
2. Link up/down interrupt is processed in bcmgenet_irq_task(), which
calls phy_mac_interrupt().
3. phy_mac_interrupt() updates the fixed PHY phydev->link and kicks
the PHY state machine.
4. PHY state machine proceeds to read the fixed PHY link status
register.
5. When the fixed PHY link status register is being read, the new
function bcmgenet_fixed_phy_link_update() gets called. It copies
the fixed PHY phydev->link value to the fixed PHY status->link.
6. PHY state machine receives the new link state of the fixed PHY.
7. MoCA fixed PHY link state now correctly reflects the real MoCA
hardware link state.

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
Moreover use devm_gpiod_get_optional instead of ignoring all errors
returned by devm_gpiod_get and simplify accordingly.
The result is more strict error handling which is good.
