The MT753x switches provide a switch-internal MDIO bus for the embedded
PHYs.
Register a OF sub-node on the switch OF-node for this internal MDIO bus.
This allows to configure the embedded PHYs using device-tree.

Early versions (?) of the RTL8221B PHY cannot be identified in a regular
Clause-45 bus scan as the PHY doesn't report the implemented MMDs
correctly but returns 0 instead.
Implement custom identify function using the PKGID instead of iterating
over the implemented MMDs to work-around this problem.

The previous attempt to replace an open coded paged read in the RealTek
Ethernet PHY driver was too naive and resulted in breaking the r8169
PCIe Ethernet driver which also makes use of the RealTek Ethernet PHY
driver.
Fix this by instead of using the (not yet populated) paged operations
rather use rtl821x_write_page and protect the whole paged read operation
using the MDIO bus mutex.

* use interface mode switching only when operating in C45 mode
Linux prevents switching the interface mode when using C22 MDIO,
hence use rate-adapter mode in case the PHY controlled via C22.
* use phy_read_paged where appropriate
* use existing generic inline functions to handle 10GbE advertisements
instead of redundantly defining register macros in realtek.c which
are not actually vendor-specific.
* make sure 10GbE advertisement is valid, preventing false-positive
warning "Downshift occurred from negotiated speed 2.5Gbps to actual
speed 1Gbps, check cabling!" with some link-partners using 1G mode.
* Support Link Down Power Saving Mode (ALDPS)

MEMREAD is a new ioctl for MTD character devices that was first included
in Linux 6.1. It allows userspace applications to use the Linux
kernel's OOB autoplacement mechanism while reading data from NAND
devices. The Yafut tool needs this ioctl to do its job.

MAC drivers don't use SGMII in-band autonegotiation unless told to do so
in device tree using 'managed = "in-band-status"'. When using MDIO to
access a PHY, in-band-status is unneeded as we have link-status via
MDIO. Switch off SGMII in-band autonegotiation using magic values.

The HG MXPD-483II 1310nm SFP module is meant to operate with 2500Base-X,
however, in their EEPROM they incorrectly specify:
Transceiver type : Ethernet: 1000BASE-LX
...
BR, Nominal : 2600MBd
Use sfp_quirk_2500basex for this module to allow 2500Base-X mode anyway.

These patches have now received a positive review upstream, so let's add them
to pending patches.
776-net-dsa-b53-mmap-add-phy-ops.patch:
This is mostly bmips/bcm63xx-specific to get external switches working
without hanging the device when accessing certain registers.
777-net-dsa-b53-mdio-add-support-for-BCM53134:
This adds support for BCM53134 switch on DSA B53, so any target using DSA B53
can benefit from it.
Also fix sercomm-h500-s external switch IMP port phy-mode.

This fixes spurious boot-errors with some ath79 MIPS 74Kc boards such
as the AC Lite as well as Archer C7 v2.
The missing barrier leads to the icache flush being executed before the
dcache writeback, which results in the CPU executing the dummy infinite
loop in tlbmiss_handler_setup_pgd.
Applying this patch from upstream ensures the dcache is written back
before flushing the icache.

This backports the third version [1], which is awaiting upstream merge. It
adds support for watchdog max6370, which is connected via GPIO. It
is useful primarily for P2020 RDB and Turris 1.x routers, which are
