Switch to the generic PCI power management framework and remove legacy
callbacks like .suspend() and .resume(). With the generic framework, the
standard PCI related work like:
- pci_save/restore_state()
- pci_enable/disable_device()
- pci_set_power_state()
is handled by the PCI core and this driver should implement only
hci_bcm4377 specific operations in its respective callback functions.

On QCS9075 and QCA8275 platforms, the BT_EN pin is always pulled up by hw
and cannot be controlled by the host. As a result, in case of a firmware
crash, the host cannot trigger a cold reset. Instead, the BT controller
performs a warm restart on its own, without reloading the firmware.
This leads to the controller remaining in IBS_WAKE state, while the host
expects it to be in sleep mode. The mismatch causes HCI reset commands
to time out. Additionally, the driver does not clear internal flags
QCA_SSR_TRIGGERED and QCA_IBS_DISABLED, which blocks the reset sequence.
If the SSR duration exceeds 2 seconds, the host may enter TX sleep mode
due to tx_idle_timeout, further preventing recovery. Also, memcoredump_flag
is not cleared, so only the first SSR generates a coredump.
Tell the driver that the BT controller has undergone a proper restart sequence:
- Clear QCA_SSR_TRIGGERED and QCA_IBS_DISABLED flags after SSR.
- Add a 50ms delay to allow the controller to complete its warm reset.
- Reset tx_idle_timer to prevent the host from entering TX sleep mode.
- Clear memcoredump_flag to allow multiple coredump captures.
Apply these steps only when HCI_QUIRK_NON_PERSISTENT_SETUP is not set,
which indicates that BT_EN is defined in DTS and cannot be toggled.
Refer to the comment in include/net/bluetooth/hci.h for details on
HCI_QUIRK_NON_PERSISTENT_SETUP.

In cxl_decoder_commit(), commit_end is incremented before verifying
whether the commit succeeded, and the CXL_DECODER_F_ENABLE bit in
cxld->flags is only set after a successful commit. As a result, if the
commit fails, commit_end has been incremented and cxld->reset() has no
effect since the flag is not set, so commit_end remains incorrectly
incremented. The inconsistency between commit_end and CXL_DECODER_F_ENABLE
causes failure during subsequent either commit or reset operations.
Fix this by incrementing commit_end only after confirming the commit
succeeded. Also, remove the ineffective cxld->reset() call. According to
CXL Spec r4.0 8.2.4.20.12 Committing Decoder Programming, since
cxld_await_commit() has cleared the decoder commit bit on failure, no
additional reset is required.

imx8qxp_pixel_link_find_next_bridge() uses a sophisticated logic to find
the preferred next bridge, using an array with two supporting index
variables. This is more sophisticated than required because we only ever
need a pointer to the "current" bridge and to the "best so far" bridge.
Additionally this logic is going to make the addition of proper refcounting
quite complex.
Rewrite the logic using two drm_bridge pointers, which is by itself
slightly simpler and is a preparation step for introducing bridge
refcounting in a later commit.
Also reword a comment to make it clearer.

values to apply. Once done, the sensors are put back in normal mode.

PAGE_SIZE aligned works. For gfx12.1, sizeof(struct mqd) == PAGE_SIZE,
it doesn't work.
KFD mqd manager hardcodes mqd size to PAGE_SIZE/MQD_SIZE across different
IP versions to solve this issue.
To avoid hardcoding in differnet places and across different IP versions.
Let's use AMDGPU_MQD_SIZE_ALIGN instead. It is used in two places.
1. mqd memory alloction
2. mqd stride handling for multi xcc config
v2: Use AMDGPU_GPU_PAGE_ALIGN. (Mukul)

Add validation to ensure user queue sizes meet hardware requirements:
- Size must be a power of two for efficient ring buffer wrapping
- Size must be at least AMDGPU_GPU_PAGE_SIZE to prevent undersized allocations
This prevents invalid configurations that could lead to GPU faults or
unexpected behavior.

Merge tag 'for-6.19-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
- fix leaked folio refcount on s390x when using hw zlib compression
acceleration
- remove own threshold from ->writepages() which could collide with
cgroup limits and lead to a deadlock when metadadata are not written
because the amount is under the internal limit
* tag 'for-6.19-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
btrfs: zlib: fix the folio leak on S390 hardware acceleration
btrfs: do not strictly require dirty metadata threshold for metadata writepages
The history of this driver is pretty amusing. It was marked broken in
2007 in
28f96eeafc ("drivers/edac-new-i82443bxgz-mc-driver: mark as broken").
It was then fixed in 2008 in
53a2fe5804 ("edac: make i82443bxgx_edac coexist with intel_agp"),
but the dependency on BROKEN was never removed. Given that this was never
fixed in the last ~18 years, it is obvious there is no demand for this driver.
Remove it and move the former maintainer to the CREDITS file.

The return value from itg3200_read_reg_s16() is stored in ret but
never checked. The function unconditionally returns IIO_VAL_INT,
ignoring potential I2C read failures. This causes garbage data to
be returned to userspace when the read fails, with no error reported.
Add proper error checking to propagate the failure to callers.
