Add new netlink attribute to allow user space configuration of reference
sync pin pairs, where both pins are used to provide one clock signal
consisting of both: base frequency and sync signal.

The Rx rings are filled with Rx buffers. Which are supposed to fit
packet headers (or MTU if HW-GRO is disabled). The aggregation buffers
are filled with "device pages". Adjust the sizes of the page pool
recycling ring appropriately, based on ratio of the size of the
buffer on given ring vs system page size. Otherwise on a system
with 64kB pages we end up with >700MB of memory sitting in every
single page pool cache.
Correct the size calculation for the head_pool. Since the buffers
there are always small I'm pretty sure I meant to cap the size
at 1k, rather than make it the lowest possible size. With 64k pages
1k cache with a 1k ring is 64x larger than we need.

net: dsa: ks8995: Fix up bindings
After looking at the datasheets for KS8995 I realized this is
a DSA switch and need to have DT bindings as such and be implemented
as such.
This series just fixes up the bindings and the offending device tree.
The existing kernel driver which is in drivers/net/phy/spi_ks8995.c
does not implement DSA. It can be forgiven for this because it was
merged in 2011 and the DSA framework was not widely established
back then. It continues to probe fine but needs to be rewritten
to use the special DSA tag and moved to drivers/net/dsa as time
permits. (I hope I can do this.)
It's fine for the networking tree to merge both patches, I maintain
ixp4xx as well. But I can also carry the second patch through the
SoC tree if so desired.

Fix up the KS8995 switch and PHYs the way that is most likely:
- Phy 1-4 is certainly the PHYs of the KS8995 (mask 0x1e in
the outoftree code masks PHYs 1,2,3,4).
- Phy 5 is the MII-P5 separate WAN phy of the KS8995 directly
connected to EthC.
- The EthB MII is probably connected as CPU interface to the
KS8995.
Properly integrate the KS8995 switch using the new bindings.

After studying the datasheets for some of the KS8995 variants
it becomes pretty obvious that this is a straight-forward
and simple MII DSA switch with one port in (CPU) and four outgoing
ports, and it even supports custom tags by setting a bit in
a special register, and elaborate VLAN handling as all DSA
switches do.
What is a bit odd with KS8995 is that it uses an extra MII-P5
port to access one of the PHYs separately, on the side of the
switch fabric, such as when using a WAN port separately from
a LAN switch in a home router.
Rewrite the terse bindings to YAML, and move to the proper
subdirectory. Include a verbose example to make things clear.

Add a device tree option to select RX gain reduction to improve EMC

Selecting a communication standard in the ISO control register resets
the RX antenna gain settings. Therefore set the RX gain reduction
everytime the ISO control register changes, when the option is used.

Airoha AN7583 SoC have 2 dedicated MDIO bus controller in the SCU
register map. To driver register an MDIO controller based on the DT
reg property and access the register by accessing the parent syscon.
The MDIO bus logic is similar to the MT7530 internal MDIO bus but
deviates of some setting and some HW bug.
On Airoha AN7583 the MDIO clock is set to 25MHz by default and needs to
be correctly setup to 2.5MHz to correctly work (by setting the divisor
to 10x).
There seems to be Hardware bug where AN7583_MII_RWDATA
is not wiped in the context of unconnected PHY and the
previous read value is returned.
Example: (only one PHY on the BUS at 0x1f)
- read at 0x1f report at 0x2 0x7500
- read at 0x0 report 0x7500 on every address
To workaround this, we reset the Mdio BUS at every read
to have consistent values on read operation.

====================
ptp: Belated spring cleaning of the chardev driver
When looking into supporting auxiliary clocks in the PTP ioctl, the
inpenetrable ptp_ioctl() letter soup bothered me enough to clean it up.
The code (~400 lines!) is really hard to follow due to a gazillion of
local variables, which are only used in certain case scopes, and a
mixture of gotos, breaks and direct error return paths.
Clean it up by splitting out the IOCTL functionality into seperate
functions, which contain only the required local variables and are trivial
to follow. Complete the cleanup by converting the code to lock guards and
get rid of all gotos.
That reduces the code size by 48 lines and also the binary text size is
80 bytes smaller than the current maze.
The series is split up into one patch per IOCTL command group for easy
review.

setup_wait() takes an optional argument and then is called from the top
level of the test script. That confuses shellcheck, which thinks that maybe
the intention is to pass $1 of the script to the function, which is never
the case. To avoid having to annotate every single new test with a SC
disable, split the function in two: one that takes a mandatory argument,
and one that takes no argument at all.
Convert the two existing users of that optional argument, both in Spectrum
resource selftest, to use the new form. Clean up vxlan_bridge_1q_mc_ul.sh
to not pass a now-unused argument.

airoha_qdma_fill_rx_queue()
Since the page_pool for airoha_eth driver is created with
PP_FLAG_DMA_SYNC_DEV flag, we do not need to sync_for_device each page

The driver currently defaults to the internal oscillator as the clock
source for E825-C hardware. While this clock source is labeled TCXO,
indicating a temperature compensated oscillator, this is only true for some
board designs. Many board designs have a less capable oscillator. The
E825-C hardware may also have its clock source set to the TIME_REF pin.
This pin is connected to the DPLL and is often a more stable clock source.
The choice of the internal oscillator is not suitable for all systems,
especially those which want to enable SyncE support.
There is currently no interface available for users to configure the clock
source. Other variants of the E82x board have the clock source configured
in the NVM, but E825-C lacks this capability, so different board designs
cannot select a different default clock via firmware.
In most setups, the TIME_REF is a suitable default clock source.
Additionally, we now fall back to the internal oscillator automatically if
the TIME_REF clock source cannot be locked.
Change the default clock source for E825-C to TIME_REF. Note that the
driver logs a dev_dbg message upon configuring the TSPLL which includes the
clock source and frequency. This can be enabled to confirm which clock
source is in use.
Longterm a proper interface to dynamically introspect and change the clock
source will be designed (perhaps some extension of the DPLL subsystem?)

TSPLL can fail when trying to lock to TIME_REF as a clock source, e.g.
when the external clock source is not stable or connected to the board.
To continue operation after failure, try to lock again to internal TCXO
and inform user about this.

To ensure proper operation, wait for 10 to 20 microseconds before
enabling TSPLL.
Adjust wait time after enabling TSPLL from 1-5 ms to 1-2 ms.
Those values are empirical and tested on multiple HW configurations.
