The setup and teardown flows are somewhat hard to follow regarding
pdsc_core_init()/pdsc_dev_init() and their corresponding teardown
flows being in pdsc_teardown(). Improve the readability by adding
new pdsc_core_uninit()/pdsc_dev_unint() functions that mirror their
init counterparts. Also, move the notify and admin qcq allocations
into pdsc_core_init(), so they can be freed in pdsc_core_uninit().

Running xmastree.py against the driver found some
RCT issues, so fix them.
Also, if allocating pdsc->intr_info in pdsc_dev_init()
fails the driver still tries to free pdsc->intr_info.
Fix this by just returning -ENOMEM since there's
nothing to free at this point of failure.

Unmasking the interrupt during the pdsc_adminq_isr
is a bit early and could cause unnecessary interrupts.
Instead always unmask after processing the adminq
and notifyq in pdsc_work_thread()->pdsc_process_adminq().
Also, since we are always unmasking, there's no need
for the local credits variable in pdsc_process_adminq().

The notifyq rides on the adminq's interrupt, so there's
no need to setup and/or access the notifyq's interrupt
index or bound_intr. The driver sets the bound_intr
using qcq->intx = -1 for the notifyq, but luckily
nothing accesses that field for notifyq. Instead of
expecting that remains the case, just clean up
the notifyq's interrupt index and bound_intr fields.

Add support for the independent control state machine per IEEE
802.1AX-2008 5.4.15 in addition to the existing implementation of the
coupled control state machine.
Introduces two new states, AD_MUX_COLLECTING and AD_MUX_DISTRIBUTING in
the LACP MUX state machine for separated handling of an initial
Collecting state before the Collecting and Distributing state. This
enables a port to be in a state where it can receive incoming packets
while not still distributing. This is useful for reducing packet loss when
a port begins distributing before its partner is able to collect.
Added new functions such as bond_set_slave_tx_disabled_flags and
bond_set_slave_rx_enabled_flags to precisely manage the port's collecting
and distributing states. Previously, there was no dedicated method to
disable TX while keeping RX enabled, which this patch addresses.
Note that the regular flow process in the kernel's bonding driver remains
unaffected by this patch. The extension requires explicit opt-in by the
user (in order to ensure no disruptions for existing setups) via netlink
support using the new bonding parameter coupled_control. The default value
for coupled_control is set to 1 so as to preserve existing behaviour.

Remove explicit calls to functions that are called by ravb_open(). There is
no need to have them doubled now that the ravb_open() already contains
what is needed for the interface configuration. Along with it,
configurations needed by PTP were moved to ravb_wol_restore(). With this,

As some IP variants switch to reset mode (and thus the register contents is
lost) when setting clocks (due to module standby functionality) to be able
to implement runtime PM and save more power, set the IP's operating mode to
reset at the end of the probe. Along with it, in the ndo_open API the IP
will be switched to configuration, then operation mode. In the ndo_close
API, the IP will be switched back to reset mode. This allows implementing
runtime PM and, along with it, save more power when the IP is not used.

ravb_set_gti() was computing the value of GTI based on the reference clock
rate and then applied it to register. This was done on the driver's probe
function. In order to implement runtime PM for all IP variants (as some IP
variants switches to reset mode (and thus the registers content is lost)
when module standby is configured through clock APIs) the GTI setup was
split in 2 parts: one computing the value of the GTI register (done in the
driver's probe function) and one applying the computed value to register
(done in the driver's ndo_open API).

The runtime PM implementation will disable clocks at the end of
ravb_probe(). As some IP variants switch to reset mode as a result of
setting module standby through clock disable APIs, to implement runtime PM
the resource parsing and requesting are moved in the probe function and IP
settings are moved in the open function. This is done because at the end of
the probe some IP variants will switch anyway to reset mode and the
registers content is lost. Also keeping only register settings operations
in the ravb_open()/ravb_close() functions will make them faster.
Commit moves IRQ requests to ravb_probe() to have all the IRQs ready when
the interface is open. As now getting/requesting IRQs is done in a single
place there is no need to keep intermediary data (like ravb_rx_irqs[] and
ravb_tx_irqs[] arrays or IRQs in struct ravb_private).
In order to avoid accessing the IP registers while the IP is runtime
suspended (e.g. in the timeframe b/w the probe requests shared IRQs and
IP clocks are enabled) in the interrupt handlers were introduced
pm_runtime_active() checks. The device runtime PM usage counter has been
incremented to avoid disabling the device's clocks while the check is in
progress (if any).
This is a preparatory change to add runtime PM support for all IP variants.

Reference clock could be or not be part of the power domain. If it is part
of the power domain, the power domain takes care of properly setting it. In
case it is not part of the power domain and full runtime PM support is
available in driver the clock will not be propertly disabled/enabled at
runtime. For this, keep the prepare/unprepare operations in the driver's
probe()/remove() functions and move the enable/disable in runtime PM
functions.
By doing this, the previous ravb_runtime_nop() function was renamed
ravb_runtime_suspend() and the comment was removed. A proper runtime PM
resume function was added (ravb_runtime_resume()). The current driver
still don't need to make any register settings on runtime suspend/resume
(as expressed in the removed comment) because, currently,
pm_runtime_put_sync() is called on the driver remove function. This will be
changed in the next commits (that extends the runtime PM support) such
that proper register settings (along with runtime resume/suspend) will be
done on ravb_open()/ravb_close().
Along with it, the other clock request operations were moved close to
reference clock request and prepare to have all the clock requests
specific code grouped together.

RZ/G3S can go to deep sleep states where power to most of the SoC parts is
off. When resuming from such a state, the Ethernet controller needs to be
reinitialized. De-asserting the reset signal for it should also be done.
Thus, add reset assert/de-assert on suspend/resume functions.
On the resume function, the de-assert was not reverted in case of failures
to give the user a chance to restore the interface (e.g., bringing down/up
the interface) in case suspend/resume failed.

ravb_rzv2m_hw_info::gptp_ref_clk is enabled only for RZ/V2M. RZ/V2M
is an ARM64-based device which selects power domains by default and
CONFIG_PM. The RZ/V2M Ethernet DT node has proper power-domain binding
available in device tree from the commit that added the Ethernet node.
(4872ca1f92b0 ("arm64: dts: renesas: r9a09g011: Add ethernet nodes")).
Power domain support was available in the rzg2l-cpg.c driver when the
Ethernet DT node has been enabled in RZ/V2M device tree.
(ef3c613ccd68 ("clk: renesas: Add CPG core wrapper for RZ/G2L SoC")).
Thus, remove the explicit clock enable for gptp_clk (and treat it as the
other clocks are treated) as it is not needed and removing it doesn't
break the ABI according to the above explanations.
By removing the enable/disable operation from the driver we can add
runtime PM support (which operates on clocks) w/o the need to handle
the gptp_clk in the Ethernet driver functions like ravb_runtime_nop().
PM domain does all that is needed.

ravb_poll() initial code used to interrogate the first descriptor of the
RX queue in case gPTP is false to determine if ravb_rx() should be called.
This is done for non-gPTP IPs. For gPTP IPs the driver PTP-specific
information was used to determine if receive function should be called. As
every IP has its own receive function that interrogates the RX descriptors
list in the same way the ravb_poll() was doing there is no need to double
check this in ravb_poll(). Removing the code from ravb_poll() leads to a
cleaner code.

In the case of XDP Multi-Buffer with Striding RQ, an extra
page is allocated for the linear part of non-linear SKBs.
Including headroom and tailroom in the calculation may
result in an unnecessary increase in the amount of memory
allocated. This could be critical, particularly for large
MTUs (e.g. 7975B) and large RQ sizes (e.g. 8192).
In this case, the requested page pool size is 64K, but
32K would be sufficient. This causes a failure due to
exceeding the page pool size limit of 32K.
Exclude headroom and tailroom from SKB size calculations

In current SWS debug dump mechanism we implement the seq_file interface,
but we only implement the 'show' callback to dump the whole steering DB
with a single call to this callback.
However, for large data size the seq_printf function will fail to
allocate a buffer with the adequate capacity to hold such data.
This patch solves this problem by utilizing the seq_file interface
mechanism in the following way:
- when the user triggers a dump procedure, we will allocate a list of
buffers that hold the whole data dump (in the start callback)
- using the start, next, show and stop callbacks of the seq_file
API we iterate through the list and dump the whole data

The CW1200 uses two GPIOs to control the powerup and reset
pins, get these from GPIO descriptors instead of being passed
as platform data from boardfiles.
The RESET line will need to be marked as active low as we will
let gpiolib handle the polarity inversion.
The SDIO case is a bit special since the "card" need to be
powered up before it gets detected on the SDIO bus and
properly probed. Fix this by using board-specific GPIOs
assigned to device "NULL".

drivers/net/wireless/st/cw1200/cw1200_spi.c:148:17: got restricted __le16 [usertype]
These cpu_to_le16() calls are not really making any sense to me. On a big
endian system we first convert regaddr from big to little using cpu_to_le16()
but immediately after we convert them back to big endian? So just remove them.
Compile tested only.

These cpu_to_le32() are not making sense. With usb_reg_buf we handle the values
byte at a time to make sure usb_reg_buf is in little endian so no need to
convert anything. And usb_control_msg() expects to have the values in native
endian anyway. So just remove these so they are not spamming our logs.
Compile tested only.

Sparse warns:
drivers/net/wireless/zydas/zd1211rw/zd_usb.c:383:24: warning: implicit cast from nocast type
drivers/net/wireless/zydas/zd1211rw/zd_usb.c:419:24: warning: implicit cast from nocast type
This is an ancient driver which has not have any meaningfuli changes for a long
time and hopefully removed soon. So just remove the __nocast to get rid of the
sparse warnings.
Compile tested only.

In the for statement of lbs_allocate_cmd_buffer(), if the allocation of
cmdarray[i].cmdbuf fails, both cmdarray and cmdarray[i].cmdbuf needs to
be freed. Otherwise, there will be memleaks in lbs_allocate_cmd_buffer().

Currently, at the end of ath11k_mac_fill_reg_tpc_info(), the
reg_tpc_info struct is populated, including the following:
reg_tpc_info->is_psd_power = is_psd_power;
reg_tpc_info->eirp_power = eirp_power;
Kernel test robot complains on uninitialized symbol:
drivers/net/wireless/ath/ath11k/mac.c:7949
ath11k_mac_fill_reg_tpc_info() error: uninitialized symbol 'eirp_power'.
This is because there are some code paths that never set eirp_power, so
the assignment of reg_tpc_info->eirp_power can come from an
uninitialized variable. Functionally this is OK since the eirp_power
only has meaning when is_psd_power is true, and all code paths which set
is_psd_power to true also set eirp_power. However, to keep the robot
happy, always initialize eirp_power before use.
