The TRF7970a device is sensitive to RF disturbances, which can make it
hard to pass some EMC immunity tests. By reducing the RX antenna gain,
the device becomes less sensitive to EMC disturbances, as a trade-off
against antenna performance.
Add a device tree option to select RX gain reduction to improve EMC
performance.
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.

* ref_tracker: do xarray and workqueue job initializations earlier
Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The kernel test robot reported an oops that occurred when attempting to
deregister a dentry from the xarray during subsys_initcall().
The ref_tracker xarrays and workqueue job are being initialized in
late_initcall() which is too late. Move those to postcore_initcall()
instead.

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.

Each MDIO controller can be independently reset with the SoC reset line.

====================
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.

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?)

fbnic_fw_clear_cmpl() does the inverse of fbnic_mbx_set_cmpl().
It removes the completion from the mailbox table.
It also calls fbnic_mbx_set_cmpl_slot() internally.
It should have fbnic_mbx prefix, not fbnic_fw.
I'm not very clear on what the distinction is between the two
prefixes but the matching "set" and "clear" functions should
use the same prefix.
While at it move the "clear" function closer to the "set".

Relign various whitespace things. Some of it is spaces which should
be tabs and some is making sure the values are actually correctly
aligned to "columns" with 8 space tabs. Whitespace changes only.

Somehow we ended up with two copies of FBNIC_MAX_[TR]XQS in fbnic_txrx.h.
Remove the one mixed with the struct declarations.

Follow-up to RGMII mode clarification: am65-cpsw fix + checkpatch
Following previous discussion [1] and the documentation update by
Andrew [2]:
Fix up the mode to account for the fixed TX delay on the AM65 CPSW
Ethernet controllers, similar to the way the icssg-prueth does it. For
backwards compatibility, the "impossible" modes that claim to have a
delay on the PCB are still accepted, but trigger a warning message.
As Andrew suggested, I have also added a checkpatch check that requires
a comment for any RGMII mode that is not "rgmii-id".
No Device Trees are updated to avoid the warning for now, to give other
projects syncing the Linux Device Trees some time to fix their drivers
as well. I intend to submit an equivalent change for U-Boot's
am65-cpsw-nuss driver as soon as the changes are accepted for Linux.

Historically, the RGMII PHY modes specified in Device Trees have been
used inconsistently, often referring to the usage of delays on the PHY
side rather than describing the board; many drivers still implement this
incorrectly.
Require a comment in Devices Trees using these modes (usually mentioning
that the delay is realized on the PCB), so we can avoid adding more
incorrect uses (or will at least notice which drivers still need to be
fixed).

All am65-cpsw controllers have a fixed TX delay, so the PHY interface
mode must be fixed up to account for this.
Modes that claim to a delay on the PCB can't actually work. Warn people
to update their Device Trees if one of the unsupported modes is specified.

k3-am65-cpsw-nuss controllers have a fixed internal TX delay, so RXID
mode is not actually possible and will result in a warning from the
driver going forward.
