With traffic ongoing for data TID [TID 0], an DELBA request to
stop AMPDU for the BA session was received on management TID [TID 4].
The corresponding TID number was incorrectly passed to stop the BA session,
resulting in the BA session for data TIDs being stopped and the BA size
being reduced to 1, causing an overall dip in TCP throughput.
Fix this issue by passing the correct argument from
ath12k_dp_rx_ampdu_stop() to ath12k_dp_arch_peer_rx_tid_reo_update()
during an AMPDU stop session. Instead of passing peer->dp_peer->rx_tid,
which is the base address of the array, corresponding to TID 0, pass
the value of &peer->dp_peer->rx_tid[params->tid]. With this, the
different TID numbers are accounted for.

During ongoing traffic, a request to stop an AMPDU session
for one TID could incorrectly affect other active sessions.
This can happen because an incorrect TID reference would be
passed when updating the BA session state, causing the wrong
session to be stopped. As a result, the affected session would
be reduced to a minimal BA size, leading to a noticeable
throughput degradation.
Fix this issue by passing the correct argument from
ath11k_dp_rx_ampdu_stop() to ath11k_peer_rx_tid_reo_update()
during a stop AMPDU session. Instead of passing peer->tx_tid, which
is the base address of the array, corresponding to TID 0; pass
the value of &peer->rx_tid[params->tid], where the different TID numbers
are accounted for.

[PLANE:32:plane 1A]: type=PRI

Display is working fine - no artefacts, no DMAR/PIPE faults.
v2:
* Adjust patch title. (Rodrigo)
v3:
* Complete rewrite based on the display parent interface.

The fallback case for DPT backing store is a buffer object in system
memory buffer, which by default use a write-back CPU caching policy.
If this fallback gets triggered, and since there is currently no flushing,
the DPT writes made when pinning a buffer to display are not guaranteed to
be seen by the display engine.
To fix this, since both the local memory and the stolen memory DPT
placements already use write-combine, let us make the system memory option
follow suit by passing down the appropriate flag.

The Rust `Regulator` abstraction uses `NonNull` to wrap the underlying
`struct regulator` pointer. When `CONFIG_REGULATOR` is disabled, the C
stub for `regulator_get` returns `NULL`. `from_err_ptr` does not treat
`NULL` as an error, so it was passed to `NonNull::new_unchecked`,
causing undefined behavior.
Fix this by using a raw pointer `*mut bindings::regulator` instead of
`NonNull`. This allows `inner` to be `NULL` when `CONFIG_REGULATOR` is
disabled, and leverages the C stubs which are designed to handle `NULL`
or are no-ops.

Add a new driver for Bitland laptops that utilize the MIFS (MiInterface)
WMI interface.
The driver implements several features through the WMI interface:
- Platform Profile: Supports "Quiet", "Balanced", "Performance", and
"Full Speed" modes. The "Full Speed" mode is intelligently restricted
based on the AC adapter type (requires DC power, not supported on
USB-C charging) as required by the hardware.
- Hwmon: Provides monitoring for CPU, GPU, and System fan speeds,
as well as CPU temperature sensors.
- Keyboard Backlight: Integrated with the LED class device for
brightness control and provides sysfs attributes for keyboard modes
(cyclic, fixed, etc.).
- GPU Mode: Allows switching between Hybrid, Discrete, and UMA
graphics modes via sysfs.
- Hotkeys: Handles WMI events for system hotkeys (Calculator, Browser,
App launch) using sparse keymaps and reports status changes for
Airplane mode, Touchpad, and CapsLock.
- Fan Boost: Provides a sysfs interface to force fans to maximum speed.
The driver registers two WMI GUIDs:
- B60BFB48-3E5B-49E4-A0E9-8CFFE1B3434B: Control methods
- 46C93E13-EE9B-4262-8488-563BCA757FEF: Event notifications

The hdmi_colorspace enum was defined to represent the colorspace value
of the HDMI infoframes. It was later used by some HDMI drivers to
express the output format they should be setting up.
During the introduction of the HDMI helpers, it then was used to
represent it in the drm_connector_hdmi_state structure.
However, it's always been somewhat redundant with the DRM_COLOR_FORMAT_*
defines, and now with the drm_output_color_format enum. Let's
consolidate around drm_output_color_format in drm_connector_hdmi_state
to facilitate the current effort to provide a global output format
selection mechanism.

Now that we introduced a new drm_output_color_format enum to represent
what DRM_COLOR_FORMAT_* bits were representing, we can switch to the new
enum.
The main difference is that while DRM_COLOR_FORMAT_ was a bitmask,
drm_output_color_format is a proper enum. However, the enum was done is
such a way than DRM_COLOR_FORMAT_X = BIT(DRM_OUTPUT_COLOR_FORMAT_X) so
the transitition is easier.

The EDID parsing code initially introduced the DRM_COLOR_FORMAT_*
defines to represent the sink capabilities. Since a given sink could
support multiple formats, it was first defined as a bitmask.
However, the core and drivers have since leveraged those defines to
represent both the supported formats but also the current format being
used.
Considering the latter case, the more natural, and consistent, thing to
do would be to create an enum of all the possible formats, and then list
the supported formats using a bitmask of the individual enum values.
Let's create a new enum following that pattern, drm_output_color_format,
while maintaining the DRM_COLOR_FORMAT_* compatibility to make the
transition easier.

The ARM SCMI pinctrl protocol allows GPIO access. Instead of creating

Traditionally, firmware will provide a GPIO interface or a pin control
interface. However, the SCMI protocol provides a generic pin control
interface and the GPIO support is built on top of that using the normal
pin control interfaces. Potentially, other firmware will adopt a
similar generic approach in the future.
Document how to configure the GPIO device.

The argument for PIN_CONFIG_OUTPUT_IMPEDANCE_OHMS is supposed to
be expressed in terms of ohms. But the pinctrl-scmi driver was
implementing it the same as PIN_CONFIG_OUTPUT and writing either a
zero or one to the pin.
The SCMI protocol doesn't have an support configuration type so just
delete this code instead of replacing it.

The PIN_CONFIG_LEVEL parameter represents the value of the pin, whether
reading or writing to the pin. In SCMI, the parameter is represented by
two different values SCMI_PIN_OUTPUT_VALUE for writing to a pin and
SCMI_PIN_INPUT_VALUE for reading. The current code translates
PIN_CONFIG_LEVEL as SCMI_PIN_OUTPUT_VALUE (writing).
Add a function to translate it to either INPUT or OUTPUT depending on
whether it is called from a _get or _set() operation.

This is a counterpart of pinctrl_gpio_set_config(), which will be used
to implement the ->get() interface in a GPIO driver for SCMI.
This also requires that we create a stub so pin_config_get_for_pin()
can build when CONFIG_PINCONF is disabled.

error path
As suggested by Simon in [0], rework the code flow in airoha_remove()
and in the airoha_probe() error path in order to rely on a more common
approach un-registering configured net-devices first and destroying the
hw resources at the end of the code.
Introduce airoha_qdma_cleanup routine to release QDMA resources.
