In preparation for the new LAG functionality implementation, there are
a couple of existing LAG elements of the capabilities struct that should
be bool instead of u8. Since we are adding a new element to this struct
that should also be a bool, fix the existing LAG u8 in this patch and
eliminate !! operators where possible.

This series will be touching on the LAG code in the ice driver,
to prevent moving or propagating casting on void pointers, clean
them up first.
This also allows for moving the variable initialization into the
variable declaration.

struct pci_epc_features has static storage duration, so all struct members
are zero initialized implicitly. Thus, remove explicit zero initialization
for features that are *not* supported so we don't have to touch existing
drivers as new features are added.

LMEM is partitioned between multiple VFs and we expect that the more
VFs we have, the less LMEM is assigned to each VF.
This means that we can achieve full LMEM BAR access without the need to
attempt full VF LMEM BAR resize via pci_resize_resource().
Always try to set the largest possible BAR size that allows to fit the
number of enabled VFs and inform the user in case the resize attempt is
not successful.

Since commit c9b1150a68d9 ("drm/atomic-helper: Re-order bridge chain
pre-enable and post-disable"), the bridge pre_enable callbacks are now
called before crtc enable, and the bridge post_disable callbacks after
the crtc disable.
In the mediatek-drm driver, this change leads to transfer errors on
mtk_dsi_host_transfer callback processing during the panel bridge
pre-enable sequence because the DSI host bridge pre_enable and CRTC
enable sequences, that are enabling the required clocks and PHY using
mtk_dsi_poweron function, are called after.
So, in order to fix this call order issue, request the DSI host bridge
be pre-enabled before panel bridge by setting pre_enable_prev_first
flag on DSI device bridge in the mtk_dsi_host_attach function.

When trying to set MCR[2], XON1 is incorrectly accessed instead. And when
writing to the TCR register to configure flow control levels, we are
incorrectly writing to the MSR register. The default value of $00 is then
used for TCR, which means that selectable trigger levels in FCR are used
in place of TCR.
TCR/TLR access requires EFR[4] (enable enhanced functions) and MCR[2]
to be set. EFR[4] is already set in probe().
MCR access requires LCR[7] to be zero.
Since LCR is set to $BF when trying to set MCR[2], XON1 is incorrectly
accessed instead because MCR shares the same address space as XON1.
Since MCR[2] is unmodified and still zero, when writing to TCR we are in
fact writing to MSR because TCR/TLR registers share the same address space
as MSR/SPR.
Fix by first removing useless reconfiguration of EFR[4] (enable enhanced
functions), as it is already enabled in sc16is7xx_probe() since commit
43c51bb573aa ("sc16is7xx: make sure device is in suspend once probed").
Now LCR is $00, which means that MCR access is enabled.
Also remove regcache_cache_bypass() calls since we no longer access the
enhanced registers set, and TCR is already declared as volatile (in fact
by declaring MSR as volatile, which shares the same address).
Finally disable access to TCR/TLR registers after modifying them by
clearing MCR[2].
Note: the comment about "... and internal clock div" is wrong and can be
ignored/removed as access to internal clock div registers (DLL/DLH)
is permitted only when LCR[7] is logic 1, not when enhanced features
is enabled. And DLL/DLH access is not needed in sc16is7xx_startup().

After commit 84a9582fd203 ("serial: core: Start managing serial controllers
to enable runtime PM") serial drivers need to provide a device in
struct uart_port.dev otherwise an oops happens. To fix this issue
for ip22zilog driver switch driver to a platform driver and setup
the serial device in sgi-ip22 code.

Delete extra checks for the ATA_DFLAG_CDL_ENABLED flag that prevent
SET FEATURES command from being issued to a drive when NCQ commands
are active.
ata_mselect_control_ata_feature() sets / clears the ATA_DFLAG_CDL_ENABLED
flag during the translation of MODE SELECT to SET FEATURES. If SET FEATURES
gets deferred due to outstanding NCQ commands, the original MODE SELECT
command will be re-queued. When the re-queued MODE SELECT goes through
the ata_mselect_control_ata_feature() translation again, SET FEATURES
will not be issued because ATA_DFLAG_CDL_ENABLED has been already set or
cleared by the initial translation of MODE SELECT.
The ATA_DFLAG_CDL_ENABLED checks in ata_mselect_control_ata_feature()
are safe to remove because scsi_cdl_enable() implements a similar logic
that avoids enabling CDL if it has been enabled already.

Commit 8d9908e8fe9c ("drm/i915/display: remove small micro-optimizations
in irq handling") not only removed the optimizations, it also enabled
wakeref asserts for the GEN11_GU_MISC_IIR access. Silence the asserts by
wrapping the access inside intel_display_rpm_assert_{block,unblock}().

Make video port registers nonvolatile. As DSP_CTRL register is written
to twice due to gamma LUT enable bit which is set outside of the main
DSP_CTRL initialization within atomic_enable (for rk356x case it is also
necessary to always disable gamma LUT before writing a new LUT) there is
a chance that DSP_CTRL value read-out in gamma LUT init/update code is
not the one which was written by the preceding DSP_CTRL initialization
code within atomic_enable. This might result in misconfigured DSP_CTRL
which leads to no visual output[1]. Since DSP_CTRL write takes effect
after VSYNC[1] the issue is not always present. When tested on Pinetab2
with kernel 6.14 it happenes only when DRM is compiled as a module[1].
In order to confirm that it is a timing issue I inserted 18ms udelay
before vop2_crtc_atomic_try_set_gamma in atomic enable and compiled DRM
as module - this has also fixed the issue.

Commit 4371fe1ba400 ("ata: libata-eh: Avoid unnecessary resets when
revalidating devices") replaced the call to ata_phys_link_offline() in
ata_eh_revalidate_and_attach() with the new function
ata_eh_link_established() which relaxes the checks on a device link
state to account for low power mode transitions. However, this change
assumed that the device port has a valid scr_read method to obtain the
SStatus register for the port. This is not always the case, especially
with older IDE/PATA adapters (e.g. PATA/IDE devices emulated with QEMU).
For such adapter, ata_eh_link_established() will always return false,
causing ata_eh_revalidate_and_attach() to go into its error path and
ultimately to the device being disabled.
Avoid this by restoring the previous behavior, which is to assume that
the link is online if reading the port SStatus register fails.
While at it, also fix the spelling of SStatus in the comment describing
the function ata_eh_link_established().

Support IPv6 Flow Label hashing. Use both inner and outer IPv6
header's Flow Label if both headers are detected. Flow Label
is unlike normal header fields, by enabling it user accepts
the unstable hash and possible reordering. Because of that
I think it's reasonable to hash over all Flow Labels we can
find, even tho we don't hash over all L3 addresses.

Without setting phy_mask for ax88772 mdio bus, current driver may create
at most 32 mdio phy devices with phy address range from 0x00 ~ 0x1f.
DLink DUB-E100 H/W Ver B1 is such a device. However, only one main phy
device will bind to net phy driver. This is creating issue during system
suspend/resume since phy_polling_mode() in phy_state_machine() will
directly deference member of phydev->drv for non-main phy devices. Then
NULL pointer dereference issue will occur. Due to only external phy or
internal phy is necessary, add phy_mask for ax88772 mdio bus to workarnoud
the issue.

The thunderbolt driver sets up device link dependencies from hotplug ports
to the Host Router (aka Native Host Interface, NHI). When resuming from
system sleep, this allows the Host Router to re-establish tunnels to
attached Thunderbolt devices before the hotplug ports resume.
To identify the hotplug ports, the driver utilizes the is_hotplug_bridge
flag which also encompasses ACPI slots handled by the ACPI hotplug driver.
Thunderbolt hotplug ports are always Hot-Plug Capable PCIe ports, so it is
more apt to identify them with the is_pciehp flag.
Similarly, hotplug ports on older Thunderbolt controllers have broken MSI
support and are quirked to use legacy INTx interrupts instead. The quirk
identifies them with is_hotplug_bridge, even though all affected ports are
also matched by is_pciehp. So use is_pciehp here as well.
