Similar to axienet, the temac driver is now architecture agnostic, and
can be at least compiled for several architectures.
Especially the fact that this is a soft IP for implementing in FPGAs
makes the current restriction rather pointless, as it could literally
appear on any architecture, as long as an FPGA is connected to the bus.

The driver hasn't been actually tried on any hardware, it is just a
drive-by patch when doing the same for axienet (a similar patch for
axienet is already merged).

This (temac and axienet) have been compile-tested for:

of course various new features as well fixes.

When merging with wireless-drivers this pull request has a conflict in:

To solve that just drop the changes from commit cf52c8a7 in
wireless-drivers and take the hunk from wireless-drivers-next as is.
The list of specific subsystem device IDs are not necessary after
commit d6f2134a (in wireless-drivers-next) anymore, the detection
is based on other characteristics of the devices.

Major changes:

* support for getting btcoex settings from Device Tree

* support QCA9377 SDIO device

* add HE rate accounting

PTP_CLK pin configuration for SJA1105 DSA driver

This series adds support for the PTP_CLK pin on SJA1105 to be configured
via the PTP subsystem, in the "periodic output" and "external timestamp
input" modes.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The SJA1105 switch family has a PTP_CLK pin which emits a signal with
fixed 50% duty cycle, but variable frequency and programmable start time.

On the second generation (P/Q/R/S) switches, this pin supports even more
functionality. The use case described by the hardware documents talks
about synchronization via oneshot pulses: given 2 sja1105 switches,
arbitrarily designated as a master and a slave, the master emits a
single pulse on PTP_CLK, while the slave is configured to timestamp this
pulse received on its PTP_CLK pin (which must obviously be configured as
input). The difference between the timestamps then exactly becomes the
slave offset to the master.

The only trouble with the above is that the hardware is very much tied
into this use case only, and not very generic beyond that:
 - When emitting a oneshot pulse, instead of being told when to emit it,
   the switch just does it "now" and tells you later what time it was,
   via the PTPSYNCTS register. [ Incidentally, this is the same register
   that the slave uses to collect the ext_ts timestamp from, too. ]
 - On the sync slave, there is no interrupt mechanism on reception of a
   new extts, and no FIFO to buffer them, because in the foreseen use
   case, software is in control of both the master and the slave pins,
   so it "knows" when there's something to collect.

These 2 problems mean that:
 - We don't support (at least yet) the quirky oneshot mode exposed by
   the hardware, just normal periodic output.
 - We abuse the hardware a little bit when we expose generic extts.
   Because there's no interrupt mechanism, we need to poll at double the
   frequency we expect to receive a pulse. Currently that means a
   non-configurable "twice a second".

The AVB table contains the CAS_MASTER field (to be added in the next

support for exactly that.

Because the PTP_CLK pin starts toggling only at a time higher than the

These fields configure the destination and source MAC address that the
switch will put in the Ethernet frames sent towards the CPU port that
contain RX timestamps for PTP.

These fields do not enable the feature itself, that is configured via
SEND_META0 and SEND_META1 in the General Params table.

The implication of this patch is that the AVB Params table will always
be present in the static config. Which doesn't really hurt.

This is needed because in a future patch, we will add another field from
this table, CAS_MASTER, for configuring the PTP_CLK pin function. That
can be configured irrespective of whether RX timestamping is enabled or
not, so always having this table present is going to simplify things a
bit.

This patch sets is introduce read_poll_timeout macro, it is an extension

one parameter in the readx_poll_timeout macro, but this macro can
supports multiple variable parameters for it. so functions like
phy_read(struct phy_device *phydev, u32 regnum) and
phy_read_mmd(struct phy_device *phydev, int devad, u32 regnum) can
use this poll timeout framework.

the first patch introduce read_poll_timeout macro, and the second patch

patches are examples using read_poll_timeout macro.

	  before read operation in read_poll_timeout macro.
	- add prefix with double underscores for some variable to avoid

devlink: Preparations for trap policers support

This patch set prepares the code for devlink-trap policer support in a
follow-up patch set [1][2]. No functional changes intended.

Policers are going to be added as attributes of packet trap groups,
which are entities used to aggregate logically related packet traps.
This will allow users, for example, to limit all the packets that
encountered an exception during routing to 10Kpps.

However, currently, device drivers register their packet trap groups
implicitly when they register their packet traps via
devlink_traps_register(). This makes it difficult to pass additional
attributes for the groups. For example, the policer bound to the group.

Therefore, this patch set converts device drivers to explicitly register
their packet trap groups. This will later allow these drivers to
register the group with additional attributes, if any.

Packet trap groups are now explicitly registered by drivers and not
implicitly registered when the packet traps are registered. Therefore,
there is no need to encode entire group structure the trap is associated
with inside the trap structure.

Instead, only pass the group identifier. Refer to it as initial group
identifier, as future patches will allow user space to move traps
