The "poll worker" that is introduced here is first used for
checking partner alternate modes, but it can later be used
for any partner task that requires a separate job to be
scheduled to the connector specific workqueues.
The mechanism allows the partner device specific tasks to be
polling tasks and also delayed tasks if necessary.
By polling the partner alternate modes with this mechanism
the long command completion timeout value can be reduced
back to normal. The long command completion timeout was only
used to work around a problem on some platforms where the EC
firmware (PPM) didn't return BUSY even when it should with
the alt mode commands.

The USB2.0 spec chapter 11.24.2.13 says that the USB port which is going
under test needs to be put in suspend state before sending the test
command. Many hubs, don't enforce this precondition and they work fine
without this step. But there are some "special" hubs, which requires to
disable the port power before sending the test command.
Because the USB spec mention that the port should be suspended, also
do this step before sending the test command. This could rise the
problem with other hubs which are not compliant with the spec and the
test command will not work if the port is suspend. If such hubs are
found, a similar workaround like the disable part could be implemented
to skip the suspend port command.

Check ethernet controller DT node for "mdio" subnode and use it with
of_mdiobus_register() when present. That allows specifying MDIO and its
PHY devices in a standard DT based way.
This is required for BCM53573 SoC support. That family is sometimes
called Northstar (by marketing?) but is quite different from it. It uses
different CPU(s) and many different hw blocks.
One of shared blocks in BCM53573 is Ethernet controller. Switch however
is not SRAB accessible (as it Northstar) but is MDIO attached.

1. Use info from DT if available
It allows describing for example a fixed link. It's more accurate than
just guessing there may be one (depending on a chipset).
2. Verify PHY ID before trying to connect PHY
PHY addr 0x1e (30) is special in Broadcom routers and means a switch
connected as MDIO devices instead of a real PHY. Don't try connecting to
it.

'cpc' and 'mc' nodes correspond with the MIPS 'Cluster Power Controller'
and 'MIPS Common Device Memory Map' which are present in some MIPS related
boards. There is already bindings documentation for these two located in:
- Documentation/devicetree/bindings/power/mti,mips-cpc.yaml
- Documentation/devicetree/bindings/bus/mti,mips-cdmm.yaml
Hence, properly update compatible strings and align nodes with already
mainlined bindings documentation. Also, move their definition to a proper
place since both of them are not related with the palmbus at all.

The value to adjust in the bridge register RALINK_PCI_IOBASE must take into
account the raw value from DT, not only the translated linux port number.
As long as io_offset is zero, the two are the same, but if you were to use
multiple host bridge in the system, or pick a different bus address in DT,
you can have a nonzero io_offset. At this means to take into account the
bus address which is used to calculate this offset, substracting it from
the IO resource start address.

pci_remap_iospace() was originally meant as an architecture specific helper
but it moved into generic code after all architectures had the same
requirements. MIPS has different requirements so it should not be shared.
The way for doing this will be using a macro 'pci_remap_iospace' defined
for those architectures that need a special treatment. Hence, put core API
function inside preprocesor conditional code for 'pci_remap_iospace'
definition.

By default MIPS architecture use function 'set_io_port_base()' to set the
virtual address of the first IO port. This function at the end sets variable
'mips_io_port_base' with the desired address. To align things and allow
to change first IO port location address for PCI, set PCI_IOBASE definition
as 'mips_io_port_base'.
