PHY-1 can be seen as a copy of PHY-0, and the difference is their base
register address, so add a function to get offset to access PHY-1.

mwifiex_ie_types_chan_list_param_set
struct mwifiex_ie_types_chan_list_param_set::chan_scan_param is treated
as a flexible array, so convert it into one so that it doesn't trip
the array bounds sanitizer[1]. Only a few places were using sizeof()
on the whole struct, so adjust those to follow the calculation pattern
to avoid including the trailing single element.
Examining binary output differences doesn't appear to show any literal
size values changing, though it is obfuscated a bit by the compiler
adjusting register usage and stack spill slots, etc.

Document
ATWILC1000/ATWILC3000
Baremetal Wi-Fi/BLE Link Controller Software Design Guide
https://tinyurl.com/yer2xhyc
says that bit 0 of the CRC7 code must always be a 1.
I confirmed that today with a logic analyzer: setting bit 0 causes
wilc1000 to accept a command with CRC7 enabled, whereas clearing bit 0
causes wilc1000 to reject the command with a CRC error.

During mac80211 reconfig, chanctx ops of multiple channels might not
be called in order as normal cases. However, we expect the first active
chanctx always to be put at our sub entity index 0. So, if it does not,
we do a swap there. Besides, reconfig won't allocate a new chanctx object.
So, we should reset the reference count when ops add chanctx.

After MLO, we will need to consider not only active chanctx but also active
interfaces (roles) to decide entity things. So in advance, we move handling
from chanctx_ops::add/remove to chanctx_ops::assign_vif/unassign_vif. Then,
we can recalculate and aware active interfaces' changes.
For now, behavior should not be really different, since active chanctx and
active interface are one-to-one mapping before MLO.

Originally, we consider weight only based on how many chanctxs that
mac80211 sets. However, we need to consider both active chanctxs and
active interfaces to distinguish MCC (multiple channel concurrent)
from impending MLO.
Although the logic of handling is extended, for now, behavior might
not be different under current condition.

Originally, we just declared two sub-entity, and according to rolling
down mechanism, we ensured that index 0 contained sub-entity as long
as there are sub-entity. So, we could use for-loop after deciding the
last index.
But, we are preparing to expand num of sub-entity for MLO. Then, there
won't be just two sub-entity. And, there might be holes between two bits
in the bitmap. So, we cannot simply do for-loop as before. Instead, we
need to follow the set bits.

Some of our calculation during concurrent mode depend on last beacon
TSF. Originally, we just set IEEE80211_HW_TIMING_BEACON_ONLY and get
what we want from mac80211. But, IEEE80211_HW_TIMING_BEACON_ONLY will
be restricted once we declare MLO.
Since we are about to consider the MLO stuffs, so sync beacon TSF by
ourselves now and unset IEEE80211_HW_TIMING_BEACON_ONLY.

WILC driver currently applies some default configuration whenever the firmware
is initialized, and sets the default preamble size to short. However, despite
this passed option, firmware is also able to successfully connect to access
points only using long preamble, so this setting does not really enforce short
preambles and is misleading regarding applied configuration.
Update default configuration and make it match the firmware behavior by passing
the existing WILC_FW_PREAMBLE_AUTO value (2 instead of 0). The updated setting
does not really alter firmware behavior since it is still capable to connect to
both short preamble and long preamble access points, but at list the setting now
expresses for real the corresponding firmware behavior.
More info: it has been implemented to address the transmission (Tx) blackout
issue observed in the 802.11b mode. The modification has no impact on the other
modes, which will continue to work as they did in the previous implementation.
This change will allow the 802.11b transmission (2, 5.5, 11Mbps) to use long
preamble.

During the cache sync test we verify that values we expect to have been
written only to the cache do not appear in the hardware. This works most
of the time but since we randomly generate both the original and new values
there is a low probability that these values may actually be the same.
Wrap get_random_bytes() to ensure that the values are different, there
are other tests which should have similar verification that we actually
changed something.
While we're at it refactor the test to use three changed values rather
than attempting to use one of them twice, that just complicates checking
that our new values are actually new.
We use random generation to try to avoid data dependencies in the tests.

MCSPI controller have few limitations regarding the transaction
size when the FIFO buffer is enabled and the WCNT feature is used
to find the end of word, in this case if WCNT is not a multiple of
the FIFO Almost Empty Level (AEL), then the FIFO empty event is not
generated correctly. In addition to this limitation, few other unknown
sequence of events that causes the FIFO empty status to not reflect the
exact status were found when FIFO is being used without DMA enabled
during extended testing in AM65x platform. Till the exact root cause
is found and fixed, revert the FIFO support without DMA.

The realtek-mdio will now use this driver instead of the generic DSA
driver ("dsa user smi"), which should not be used with OF[1].
With a single ds_ops for both interfaces, the ds_ops in realtek_priv is
no longer necessary. Now, the realtek_variant.ds_ops can be used
directly.
The realtek_priv.setup_interface() has been removed as we can directly
call the new common function.

is unnecessary.
Since commit 3b73a7b8ec38 ("net: mdio_bus: add refcounting for fwnodes

The binding docs requires for SMI-connected devices that the switch
must have a child node named "mdio" and with a compatible string of
"realtek,smi-mdio". Meanwile, for MDIO-connected switches, the binding

This patch changes the driver to use the common denominator for both

Previously, the interface modules realtek-smi and realtek-mdio served as
a platform and an MDIO driver, respectively. Each interface module
redundantly specified the same compatible strings for both variants and
referenced symbols from the variants.
Now, each variant module has been transformed into a unified driver
serving both as a platform and an MDIO driver. This modification
reverses the relationship between the interface and variant modules,
with the variant module now utilizing symbols from the interface
modules.

Pull firewire fix from Takashi Sakamoto:
"A change to accelerate the device detection step in some cases.
In the self-identification step after bus-reset, all nodes in the same
bus broadcast selfID packet including the value of gap count. The
value is related to the cable hops between nodes, and used to
calculate the subaction gap and the arbitration reset gap.
When each node has the different value of the gap count, the
asynchronous communication between them is unreliable, since an
asynchronous transaction could be interrupted by another asynchronous
transaction before completion. The gap count inconsistency can be
resolved by several ways; e.g. the transfer of PHY configuration
packet and generation of bus-reset.
The current implementation of firewire stack can correctly detect the
gap count inconsistency, however the recovery action from the
inconsistency tends to be delayed after reading configuration ROM of
root node. This results in the long time to probe devices in some
combinations of hardware.
Here the stack is changed to schedule the action as soon as possible"

QCA8072/5 have up to 2 LEDs attached for PHY.
LEDs can be configured to be ON/hw blink or be set to HW control.
Hw blink mode is set to blink at 4Hz or 250ms.
PHY can support both copper (TP) or fiber (FIBRE) kind and supports
different HW control modes based on the port type.
HW control modes supported for netdev trigger for copper ports are:
- LINK_10
- LINK_100
- LINK_1000
- TX
- RX
- FULL_DUPLEX
- HALF_DUPLEX
HW control modes supported for netdev trigger for fiber ports are:
- LINK_100
- LINK_1000
- TX
- RX
- FULL_DUPLEX
- HALF_DUPLEX
LED support conflicts with GPIO controller feature and must be disabled
if gpio-controller is used for the PHY.

Generalize some qca808x LED functions in preparation for qca807x LED
support.
The LED implementation of qca808x and qca807x is the same but qca807x
supports also Fiber port and have different hw control bits for Fiber
port. To limit code duplication introduce micro functions that takes reg
instead of LED index to tweak all the supported LED modes.

In preparation for qca807x introduction, move all the common define to
shared header.

This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s.
They are 2 or 5 port IEEE 802.3 clause 22 compliant 10BASE-Te,
100BASE-TX and 1000BASE-T PHY-s.
They feature 2 SerDes, one for PSGMII or QSGMII connection with
MAC, while second one is SGMII for connection to MAC or fiber.
Both models have a combo port that supports 1000BASE-X and
100BASE-FX fiber.
PHY package can be configured in 3 mode following this table:
First Serdes mode Second Serdes mode
Option 1 PSGMII for copper Disabled
ports 0-4
Option 2 PSGMII for copper 1000BASE-X / 100BASE-FX
ports 0-4
Option 3 QSGMII for copper SGMII for
ports 0-3 copper port 4
Each PHY inside of QCA807x series has 4 digitally controlled
output only pins that natively drive LED-s.
But some vendors used these to driver generic LED-s controlled
by userspace, so lets enable registering each PHY as GPIO
controller and add driver for it.
These are commonly used in Qualcomm IPQ40xx, IPQ60xx and IPQ807x
boards.

Some PHY driver might require additional regs call after
genphy_c37_read_status() is called.
Expand genphy_c37_read_status to provide a bool wheather the link has
changed or not to permit PHY driver to skip additional regs call if
nothing has changed.
Every user of genphy_c37_read_status() is updated with the new
additional bool.

Move more function to shared library in preparation for introduction of
new PHY Family qca807x that will make use of both functions from at803x
and qca808x as it's a transition PHY with some implementation of at803x
and some from the new qca808x.

Add devm/of_phy_package_join helper to join PHYs in a PHY package. These
are variant of the manual phy_package_join with the difference that
these will use DT nodes to derive the base_addr instead of manually
passing an hardcoded value.
An additional value is added in phy_package_shared, "np" to reference
the PHY package node pointer in specific PHY driver probe_once and
config_init_once functions to make use of additional specific properties
defined in the PHY package node in DT.
The np value is filled only with of_phy_package_join if a valid PHY
package node is found. A valid PHY package node must have the node name
set to "ethernet-phy-package".

Add support for scanning PHY in PHY package nodes. PHY packages nodes
are just container for actual PHY on the MDIO bus.
Their PHY address defined in the PHY package node are absolute and
reflect the address on the MDIO bus.
mdio_bus.c and of_mdio.c is updated to now support and parse also
PHY package subnode by checking if the node name match
"ethernet-phy-package".
As PHY package reg is mandatory and each PHY in the PHY package must
have a reg, every invalid PHY Package node is ignored and will be
skipped by the autoscan fallback.
