Using device_find_child() and of_find_device_by_node() to locate
devices could cause an imbalance in the device's reference count.
device_find_child() and of_find_device_by_node() both call
get_device() to increment the reference count of the found device
before returning the pointer. In mtk_drm_get_all_drm_priv(), these
references are never released through put_device(), resulting in
permanent reference count increments. Additionally, the
for_each_child_of_node() iterator fails to release node references in
all code paths. This leaks device node references when loop
termination occurs before reaching MAX_CRTC. These reference count
leaks may prevent device/node resources from being properly released
during driver unbind operations.
As comment of device_find_child() says, 'NOTE: you will need to drop
the reference with put_device() after use'.

The driver is designed to support error detection and reporting for
Cortex A72 cores, specifically within their L1 and L2 cache systems.
The errors are detected by reading CPU/L2 memory error syndrome
registers.
Unfortunately there is no robust way to inject errors into the caches,
so this driver doesn't contain any code to actually test it. It has
been tested though with code taken from an older version [1] of this
driver. For reasons stated in thread [1], the error injection code is
not suitable for mainline, so it is removed from the driver.

In 32-bit arm, the build fails with:
error[E0308]: mismatched types

42 | getparam.set_value(value);

| ^^^^^^^^^ ------
help: you can convert a `u32` to a `u64`
|
42 | getparam.set_value(value.into());
| +++++++
The reason is that `Getparam::set_value` takes a `u64` (from the UAPI),
but `pci::Device::resource_len()` returns a `resource_size_t`, which is a
`phys_addr_t`, which may be 32- or 64-bit.
Thus add an `into()` call to support the 32-bit case, while allowing the
Clippy lint that complains in the 64-bit case where the type is the same.

When a poison is consumed on the guest before the guest receives the host's poison creation msg, a corner case may occur to have poison_handler complete processing earlier than it should to cause the guest to hang waiting for the req_bad_pages reply during a VF FLR, resulting in the VM becoming inaccessible in stress tests.
To fix this issue, this patch refactored the mailbox sequence by seperating the bad_page_work into two parts req_bad_pages_work and handle_bad_pages_work.
Old sequence:
1.Stop data exchange work
2.Guest sends MB_REQ_RAS_BAD_PAGES to host and keep polling for IDH_RAS_BAD_PAGES_READY
3.If the IDH_RAS_BAD_PAGES_READY arrives within timeout limit, re-init the data exchange region for updated bad page info
else timeout with error message
New sequence:
req_bad_pages_work:
1.Stop data exhange work
2.Guest sends MB_REQ_RAS_BAD_PAGES to host
Once Guest receives IDH_RAS_BAD_PAGES_READY event
handle_bad_pages_work:
3.re-init the data exchange region for updated bad page info

The function dc_stream_set_cursor_attributes() currently dereferences
the `stream` pointer and nested members `stream->ctx->dc->current_state`
without checking for NULL.
All callers of these functions, such as in
`dcn30_apply_idle_power_optimizations()` and
`amdgpu_dm_plane_handle_cursor_update()`, already perform NULL checks
before calling these functions.

HMM assumes that pages have READ permissions by default. Inside
svm_range_validate_and_map, we add READ permissions then add WRITE
permissions if the VMA isn't read-only. This will conflict with regions
that only have PROT_WRITE or have PROT_NONE. When that happens,
svm_range_restore_work will continue to retry, silently, giving the
impression of a hang if pr_debug isn't enabled to show the retries..
If pages don't have READ permissions, simply unmap them and continue. If
they weren't mapped in the first place, this would be a no-op. Since x86
doesn't support write-only, and PROT_NONE doesn't allow reads or writes
anyways, this will allow the svm range validation to continue without
getting stuck in a loop forever on mappings we can't use with HMM.

This change introduces infrastructure to check whether VCN reset
is supported by the SMU firmware. Key changes include:
1. Added new functions to query VCN reset support:
- amdgpu_dpm_reset_vcn_is_supported()
- smu_reset_vcn_is_supported()
- pptable_funcs.reset_vcn_is_supported callback
2. Implemented proper locking in the DPM layer with mutex protection
3. Maintained consistency with existing SDMA reset support checks
The new capability allows callers to check for VCN reset support
before attempting the operation, preventing unnecessary attempts
on unsupported platforms.

In order to let DRM framework handle such configurations, disable
DRM_BRIDGE_OP_DETECT for dp-connector devices, letting the actual DP
driver perform detection. This still keeps DRM_BRIDGE_OP_HPD enabled, so
it is valid for the bridge to report HPD events.
Currently inside the kernel there are only two targets which list
hpd-gpios for dp-connector devices: arm64/qcom/qcs6490-rb3gen2 and
arm64/qcom/sa8295p-adp. Both should be fine with this change.

Commit
7ffeb2fc2670 ("x86/sev: Document requirement for linear mapping of guest request buffers")
added a check that requires the guest request buffers to be in the linear
mapping. The get_derived_key() function was passing a buffer that was
allocated on the stack, resulting in the call to snp_send_guest_request()
returning an error.
Update the get_derived_key() function to use an allocated buffer instead
of a stack buffer.
Fixes: 7ffeb2fc2670 ("x86/sev: Document requirement for linear mapping of guest request buffers")

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(),
pm_runtime_autosuspend() and pm_request_autosuspend() now include a call
to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to
pm_runtime_mark_last_busy().

This replaces devm_request_irq() with devm_request_threaded_irq().
On iMX93 11x11 EVK platform, the BT chip's BT_WAKE_OUT pin is connected
to an I2C GPIO expander instead of directly been connected to iMX GPIO.
When I2C GPIO expander's (PCAL6524) host driver receives an interrupt on
it's INTR line, the driver's interrupt handler needs to query the
interrupt source with PCAL6524 first, and then call the actual interrupt
handler, in this case the IRQ handler in BTNXPUART.
In order to handle interrupts when such I2C GPIO expanders are between
the host and interrupt source, devm_request_threaded_irq() is needed.
This commit also removes the IRQF_TRIGGER_FALLING flag, to allow setting
the IRQ trigger type from the device tree setting instead of hardcoding
in the driver.

Keep track of effect's loop_count to reduce the spam of ffb play
commands coming from some games. This should speed up normal magnitude
etc updates and slightly increase max possible FFB refresh rate.
Helps games like Dirt Rally 2.0, F1 2023, WRC from KT

One of the more complicated functions. Expunge some of the logic to
separate functions (FF -> PID id conversion)
Add a macro for envelope check to make it more readable in the upload
function.
All this made it possible to to expunge common code from the big switch
statement and reduce the overall function size considerably. Now it can
fit on one screen.
Move the effect_cout logic from report functions to upload/erase
functions.

Better indicate what operation is requested on a given effect (play or
stop). Previously, we only had the info about requesting playback but
this could be misleading when the looop count is 0.
Add debug print that shows what device control command was actually sent
to the device. Print out its hex hid usage.
Make field_index const to make sure it won't be changed by mistake later.

AXES_ENABLE can be used in place of DIRECTION_ENABLE to indicate, which
FFB-enabled axes will be affected by a given effect. EFFECT_DIRECTION
enables all and uses the first direction only while AXES_ENABLE is a
bitmask and bit indexes are the same as the defined GD usages in the
EFFECT_DIRECTION array. Each axis can have it's own direction in this
case.
Search for AXES_ENABLE, set AXES_ENABLE for all axes if DIRECTION_ENABLE
is not used.
Search for specific axes in the direction array. Save their indexes. This
let us know what axes are actually available on the device and which bit
in the AXES_ENABLE field corresponds to which axis.
