When the MAC address is supplied via device tree or a random
MAC is generated it has to be written to the asix chip in
order to receive any data.
Previously in 9fb137aef34e ("net: usb: ax88179_178a: allow
optionally getting mac address from device tree") this line was
omitted because it seemed to work perfectly fine without it.
But it was simply not detected because the chip keeps the mac
stored even beyond a reset and it was tested on a hardware
with an integrated UPS where the asix chip was permanently
powered on even throughout power cycles.

net: ftgmac100: Ungate RCLK for RMII on ASPEED MACs
This series slightly extends the devicetree binding and driver for the
FTGMAC100 to describe an optional RMII RCLK gate in the clocks property.
Currently it's necessary for the kernel to ungate RCLK on the AST2600 in NCSI
configurations as u-boot does not yet support NCSI (which uses the
R(educed)MII).
v2:
* Clear up Reduced vs Reversed MII in the cover letter
* Mitigate anxiety in the commit message for 1/3
* Clarify that AST2500 is also affected in the clocks property description in
2/3
* Rework the error paths and update some comments in 3/3

SPI is one of the interfaces used to access devices which have a POSIX
clock driver (real time clocks, 1588 timers etc). The fact that the SPI
bus is slow is not what the main problem is, but rather the fact that
drivers don't take a constant amount of time in transferring data over
SPI. When there is a high delay in the readout of time, there will be
uncertainty in the value that has been read out of the peripheral.
When that delay is constant, the uncertainty can at least be
approximated with a certain accuracy which is fine more often than not.
Timing jitter occurs all over in the kernel code, and is mainly caused
by having to let go of the CPU for various reasons such as preemption,
servicing interrupts, going to sleep, etc. Another major reason is CPU
dynamic frequency scaling.
It turns out that the problem of retrieving time from a SPI peripheral
with high accuracy can be solved by the use of "PTP system
timestamping" - a mechanism to correlate the time when the device has
snapshotted its internal time counter with the Linux system time at that
same moment. This is sufficient for having a precise time measurement -
it is not necessary for the whole SPI transfer to be transmitted "as
fast as possible", or "as low-jitter as possible". The system has to be
low-jitter for a very short amount of time to be effective.
This patch introduces a PTP system timestamping mechanism in struct
spi_transfer. This is to be used by SPI device drivers when they need to
know the exact time at which the underlying device's time was
snapshotted. More often than not, SPI peripherals have a very exact
timing for when their SPI-to-interconnect bridge issues a transaction
for snapshotting and reading the time register, and that will be
dependent on when the SPI-to-interconnect bridge figures out that this
is what it should do, aka as soon as it sees byte N of the SPI transfer.
Since spi_device drivers are the ones who'd know best how the peripheral
behaves in this regard, expose a mechanism in spi_transfer which allows
them to specify which word (or word range) from the transfer should be
timestamped.
Add a default implementation of the PTP system timestamping in the SPI
core. This is not going to be satisfactory performance-wise, but should
at least increase the likelihood that SPI device drivers will use PTP
system timestamping in the future.
There are 3 entry points from the core towards the SPI controller
drivers:
- transfer_one: The driver is passed individual spi_transfers to
execute. This is the easiest to timestamp.
- transfer_one_message: The core passes the driver an entire spi_message
(a potential batch of spi_transfers). The core puts the same pre and
post timestamp to all transfers within a message. This is not ideal,
but nothing better can be done by default anyway, since the core has
no insight into how the driver batches the transfers.
- transfer: Like transfer_one_message, but for unqueued drivers (i.e.
the driver implements its own queue scheduling).
