Qualcomm IPQ40xx SoC-s have a variant of QCA8337N switch built-in.
It shares most of the stuff with its external counterpart, however it is
modified for the SoC.
Namely, it doesn't have second CPU port (Port 6), so it has 6 ports
instead of 7.
It also has no built-in PHY-s but rather requires external PSGMII based
companion PHY-s (QCA8072 and QCA8075) for which it first needs to carry
out calibration before using them.
PSGMII has a SoC built-in PHY that is used to connect to the PHY-s which
unfortunately requires some magic values as the datasheet doesnt document
the bits that are being set or the register at all.
Since its built-in it is MMIO like other peripherals and doesn't have its
own MDIO bus but depends on the SoC provided one.
CPU connection is at Port 0 and it uses some kind of a internal connection
and no traditional RGMII/SGMII.
It also doesn't use in-band tagging like other qca8k switches so a shinfo
based tagger is used.
This is based on the current OpenWrt qca8k version that has been imported
from generic target.

IPQESS is the EDMA replacement driver for the IPQ40xx SoC built-in
ethernet controller.
Unlike EDMA it is Phylink based and doesnt touch PHY-s directly.

There is no point in using a DT property to trigger setting the PSGMII
PHY AZ transmitting ability.
Especially since EEE can be disabled using ethtool anyway.
Fixup the mask for setting the workaround as only BIT(0) is actually being
changed and use the phy_clear_bits_mmd helper instead of reading, then
clearing the bit and writing back as it does everything for us.

Currently, QCA807x doesnt do any kind of validation to see whether it
actually supports the inserted module.
So lets add checks to allow only 1000BaseX and 100BaseFX based modules.
While adding validation, move fiber configuration to insert/remove events
instead of always doing it at config time.
This allows getting rid of the DT property for fiber enable and now only
the upstream sfp phandle is required.
Since we are refactoring fiber related code, lets heavily simplify the
status polling as the current logic is overcomplicated due to previous
wish to support non standard SFP cages that dont have pins properly
connected, that is removed now and only proper SFP cages will work.

MDIO drivers were moved into their own sub directory of networking drivers.
This has caused the AR40xx driver to probe before MDIO drivers and that wont
work as it depends on the MDIO bus to be up so it can be fetched.
Lets solve it by moving the AR40xx into MDIO folder so they get probed like
before.

Since we now have a proper PHY driver for QCA807x and AR803x has already
been supported properly there is no need for the driver to be poking
on PHY registers for ethtool ops.
So, lets simply use the generic
phy_ethtool_ksettings_get/phy_ethtool_ksettings_set functions.
This also has the advantage of properly populating stuff other than
speeds like, transceiver type, MDI-X etc.

Since we now have proper PHY driver for the QCA807x PHY-s, lets remove
PHY handling from AR40xx.
This removes PHY driver, PHY GPIO driver and PHY init code.
AR40xx still needs to handle PSGMII calibration as that requires R/W
from the switch, so I am unable to move it into PHY driver.
This also converted the AR40xx driver to use OF_MDIO to find the MDIO
bus as it now cant be set through the PHY driver.
So lets depend on OF_MDIO in KConfig.

This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s.
They are 2 or 5 port IEEE 802.3 clause 22 compliant
10BASE-Te, 100BASE-TX and 1000BASE-T PHY-s.
They feature 2 SerDes, one for PSGMII or QSGMII connection with MAC,
while second one is SGMII for connection to MAC or fiber.
Both models have a combo port that supports 1000BASE-X and 100BASE-FX
fiber.
Each PHY inside of QCA807x series has 2 digitally controlled output only
pins that natively drive LED-s.
But some vendors used these to driver generic LED-s controlled by
user space, so lets enable registering each PHY as GPIO controller and
add driver for it.
This also adds the ability to specify DT properties so that 1000 Base-T
LED will also be lit up for 100 and 10 Base connections.
This is usually done by U-boot, but boards running mainline U-boot are
not configuring this yet.
These PHY-s are commonly used in Qualcomm IPQ40xx, IPQ60xx and IPQ807x
boards.

With the reworked MDIO driver, EDMA will fail to get the MII BUS as it
used the MII BUS stored inside the MDIO structure private data.
This obviously does not work with the modernized driver, so lets switch
to using a purpose build of_mdio_find_bus() which will return the MII
BUS and only requires the MDIO node to be passed.
This is easy as we already have the node parsed.
Also, since we now require OF_MDIO add that as dependency.
