Because video duration involves calculating the streaming time, and i2c
communication incurs too many XTALK register settings every 4 bytes with
i2c START and STOP.
So we have opted switch to the i2c burst method.
This method involves writing the XTALK registers in the order of
the register block.
The start streaming time can be reduced from around 400ms to 150ms

Unmasking the interrupt during the pdsc_adminq_isr

Instead always unmask after processing the 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.

Intel Wired LAN Driver Updates 2024-02-02 (ice)
This series contains updates to ice driver only.
Maciej changes some queue configuration calls to existing ones which are
better suited for the purpose.
Aniruddha adds separate reporting for Rx EIPE errors as hardware may
incorrectly report errors on certain packets.
Paul removes an incorrect comment.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: remove incorrect comment
ice: Add a new counter for Rx EIPE errors
ice: make ice_vsi_cfg_txq() static
ice: make ice_vsi_cfg_rxq() static

Device driver structures are shared between all devices that they
match, and thus nothing should never write to the device driver
structure through the phydev->drv pointer. Let's make this pointer
const to catch code that attempts to do so.

This change uses the appropriate _cansleep or non-sleeping API for
reading GPIO read-only state. This allows users with GPIOs that
never sleepbeing called in atomic context.
Implement the same mechanism as in commit 52af318c93 ("mmc: Allow
non-sleeping GPIO cd").

Since commit 52df157f17 ("xfrm: take refcnt of dst when creating
struct xfrm_dst bundle") dst_destroy() returns only NULL and no caller
cares about the return value.
There are no in in-tree users of dst_destroy() outside of the file.
Make dst_destroy() static and return void.

If GUP fails and we are in_kthread, we can have pinned = 0 and ret = 0.
If that happens we call sg_alloc_append_table_from_pages() with n_pages
= 0, which is not well behaved and can trigger:
kernel BUG at include/linux/scatterlist.h:115!
depending on if the pages array happens to be zeroed or not. Even if we
don't hit that it crashes later when trying to dma_map the returned
table.

Company name in compatible description appears twice, which is not really
helpful, so remove it from product name.
The board is a prototype developed by my company and we are still at the
prototype stage, so there is zero ABI impact.
