f86273e742 ath79: Fix PHY access over ag71xx driver
.ndo_do_ioctl is not called any more. For PHY MII ioctl handling, the

150d0ceab7 ath79: ag71xx: support probe defferal for getting MAC address
Currently, of_get_ethdev_address() return is checked for any return error
code which means that trying to get the MAC from NVMEM cells that is backed
by MTD will fail if it was not probed before ag71xx.

So, lets check the return error code for EPROBE_DEFER and defer the ag71xx
probe in that case until the underlying NVMEM device is live.

ec85e48a11 ath79: add support for reset key on MikroTik RB912UAG-2HPnD
On MikroTik RB91x board series a reset key shares SoC gpio
line #15 with NAND ALE and NAND IO7. So we need a custom
gpio driver to manage this non-trivial connection schema.
Also rb91x-nand needs to have an ability to disable a polling
of the key while it works with NAND.

While we've been integrating rb91x-key into a firmware, we've
figured out that:
* In the gpio-latch driver we need to add a "cansleep" suffix to
several gpiolib calls,
* When gpio-latch and rb91x-nand fail to get a gpio and an error
is -EPROBE_DEFER, they shouldn't report about this, since this
actually is not an error and occurs when the gpio-latch probe
function is called before the rb91x-key probe.
We fix these related things here too.

ac4a21141a ath79: ag71xx: Disable napi related interrupts during probe
ag71xx_probe is registering ag71xx_interrupt as handler for the gmac0/gmac1
interrupts. The handler is trying to use napi_schedule to handle the
processing of packets. But the netif_napi_add for this device is
called a lot later in ag71xx_probe.

It can therefore happen that a still running gmac0/gmac1 is triggering the
interrupt handler with a bit from AG71XX_INT_POLL set in
AG71XX_REG_INT_STATUS. The handler will then call napi_schedule and the
napi code will crash the system because the ag->napi is not yet
initialized:

91a52f22a1 treewide: backport support for nvmem on non platform devices
In the current state, nvmem cells are only detected on platform device.
To quickly fix the problem, we register the affected problematic driver
with the of_platform but that is more an hack than a real solution.
Backport from net-next the required patch so that nvmem can work also
with non-platform devices and rework our current patch.
Drop the mediatek and dsa workaround and rework the ath10k patches.
Rework every driver that use the of_get_mac_address api.

6561ca1fa5 ath79: ar934x: fix mounting issues if subpage is not supported
Currently, the option to disable subpage writing is only set
when a HW ECC engine is used.

Some boards lack a HW ECC engine and use software for that.
In this case, this NAND option does not get set when the NAND chip
does not support it, resulting in mounting errors.

Move the setting of this option to a generic init location so it
gets set for all types where required.

While at it, also OR the option instead of just setting it
so we don't overwrite potential flags being set somewhere else.

f724a583dc ath79: mikrotik: update nand-rb4xx driver
This updates the NAND driver for MikroTik RB4XX series to work with
kernel 5.10, similarly to the ar934x-nand driver (fb64e2c3).

Support for kernel 5.10 was added to all ath79 subtargets except for the
mikrotik one by commit d6b785d, since patch 920-mikrotik-rb4xx.patch
needed to be reworked. Later, commit f8512661 enabled kernel 5.10 for
the mikrotik subtarget with the nand-rb4xx driver still pending, which
is updated and added back by this patch.

Compile-tested only.

fbbad9a9a6 ath79: force SGMII SerDes mode to MAC operation
The mode on the SGMII SerDes on the QCA9563 is 1000 Base-X by default.
This only allows for 1000 Mbit/s links, however when used with an SGMII
PHY in 100 Mbit/s link mode, the link remains dead.

This strictly has nothing to do with the SerDes calibration, however it
is done at the same point in the QCA reference U-Boot which is the
blueprint for everything happening here. As the current state is more or
less a hack, this should be fine.

This fixes the issues outlined above on a TP-Link EAP-225 Outdoor.

Extends commit 0d416a8d3b for QCA956x.
Note that reset is the same on QCA955x and QCA956x, same register offset
and values.

0x7. Add a DTS entry serdes-cal in case a device require another value.
