xe_guc_ct_init_noalloc() allocates the CT workqueue and other helpers
before it tries to initialize ct->lock. If drmm_mutex_init() fails
we currently bail out without releasing those resources because the
guc_ct_fini() hasn’t been registered yet.
Since destroy_workqueue() in guc_ct_fini() may flush the workqueue, which
in turn can take the ct lock, the initialization sequence is restructured
to first initialize the ct->lock, then set up all CT state, and finally
register guc_ct_fini().
v2: guc_ct_fini() does take ct lock. (Matt)
v3: move primelockdep() together with drmm_mutex_init(). (Lucas)

arm64: tegra: Device tree changes for v6.19-rc1
This contains a bunch of additions and improvements for older devices.
Tegra210 devices now have empty reserved-memory nodes to improve inter-
operability with certain bootloaders. These chips now also support more
multimedia engines. A new variant of the Jetson Nano is also added.
Jetson TX2 sees some improvements. PCI endpoint mode is improved for
Tegra234 so that reset interrupts are properly routed.
A new RTC device is added starting with Orin.
Rounding things off is a flurry of small fixes for DT validation and USB
OTG mode.

The macros IN_FROM_REG, TEMP_FROM_REG, and RPM_FROM_REG evaluate their
arguments multiple times. These macros are used in lockless show functions
involving shared driver data, leading to Time-of-Check to Time-of-Use race
conditions.
For example, RPM_FROM_REG checks if a value is 0 or 255, and then uses it
in a division. If the value is modified by another thread to 0 after the
check but before the division, it causes a divide-by-zero error.
Convert these macros to static functions. This guarantees that arguments
are evaluated only once (pass-by-value), fixing the race conditions.
Adhere to the principle of minimal changes by only converting the specific
macros involved in these lockless contexts.

MediaTek ARM64 Device Tree updates
This adds support for new boards and variants based on different
already supported MediaTek SoCs, and improves support for current
boards.
In particular:
- New machines:
- MT7988 BananaPi R4 Pro eMMC and SD router board with support
for both Key-M and Key-E M.2 slots through DTB Overlays
- MT8370 Grinn GenioSBC-510 (GenioSOM-510 + GenioBoard Edge AI)
- MT8390 Grinn GenioSBC-700 (GenioSOM-700 + GenioBoard Edge AI)
- New variant: MT8395 MediaTek Genio 1200 EVK with UFS
...preparation for new SoCs (MT8196 Kompanio Ultra, a clone of the
MT6991 Dimensity 9400, and MT6878 Dimensity 7300) with the
addition of GCE/PIO definitions
...improvements for already supported SoCs and machines:
- MT7622/7981b/7986a/7988a gain support for reading SoC UUID from
eFuse, used to generate a persistent MAC address on boards that
don't have any factory-assigned addresses.
- MT7986 BananaPi R3 gets changes to its default fan PWM speed to
improve compatibility with cheaper fans (usually coming with the
heatsink+fan combos)
- The MT7981b OpenWRT One router sees general support improvements
with the enablement of its UART-0 console and correct pinmuxing
for the same, addition of reserved memory for Trusted Firmware A,
its SPI NOR Flash (for recovery system, WiFi eeprom data and ETH
MAC address from factory), and board LEDs.
- MT8365 gets support for its Mali G52 MC1 GPU, which gets enabled
in the MediaTek Genio 350 EVK board
...and a dt-bindings warning fix for MT8183 machines through trivial
changes to rename the audiosys and afe nodes to reflect bindings.

The Ayaneo EC resets after hibernation, losing the charge control state.
Add a small PM hook to restore this state on hibernation resume.
The fan speed is also lost during hibernation, but since hibernation
failures are common with this class of devices, setting a low fan speed
when the userspace program controlling the fan will potentially not
take over could cause the device to overheat, so it is not restored.

Currently, the oxpec driver contains Ayaneo devices. Move them to the
new ayaneo-ec driver, which is dedicated to them.
As this driver supports charge inhibition for Ayaneo, add support for it
for the AIR, AIR 1S, AB05-Medoncino, AIR Pro, and Kun, referenced from
the out-of-tree ayaneo-platform driver.
In addition, update the readmes of oxpec to reflect this change.

The Ayaneo 3 features hot-swappable controller modules. The ejection
and management is done through HID. However, after ejecting the modules,
the controller needs to be power cycled via the EC to re-initialize.
For this, the EC provides a variable that holds whether the left or
right modules are connected, and a power control register to turn
the controller on or off. After ejecting the modules, the controller
should be turned off. Then, after both modules are reinserted,
the controller may be powered on again to re-initialize.
This patch introduces two new sysfs attributes:
- `controller_modules`: a read-only attribute that indicates whether
the left and right modules are connected (none, left, right, both).
- `controller_power`: a read-write attribute that allows the user
to turn the controller on or off (with '1'/'0').
Therefore, after ejection is complete, userspace can power off the
controller, then wait until both modules have been reinserted
(`controller_modules` will return 'both') to turn on the controller.

Ayaneo devices support charge inhibition via the EC. This inhibition
only works while the device is powered on, and resets between restarts.
However, it is maintained across suspend/resume cycles.
The EC does not support charge threshold control. Instead, userspace
software on Windows manually toggles charge inhibition depending on
battery level.

First batch of ASPEED Arm devicetree changes for 6.19
Significant changes:
- The IBM Power11 FSI DTSIs have been rearranged to accommodate new systems
New platforms:
- IBM Balcones
The Balcones system is similar to Bonnell but with a POWER11 processor.
Like POWER10, the POWER11 is a dual-chip module, so a dual chip FSI
tree is needed.
- Meta Yosemite5
The Yosemite5 platform provides monitoring of voltages, power,
temperatures, and other critical parameters across the motherboard,
CXL board, E1.S expansion board, and NIC components.
Updated platforms:
- clemente (Meta): LEDs, shunt resistor configuration
- santabarbara (Meta): AMD APML, EEPROMs, LEDs, GPIO line names, MCTP for NICs
There are a scattering of one-off changes and devicetree cleanups for other
platforms as well.

The sii902x driver was caching HDMI detection state in a sink_is_hdmi field
and checking it in mode_set() to determine whether to set HDMI or DVI
output mode. This approach had two problems:
1. With DRM_BRIDGE_ATTACH_NO_CONNECTOR (used by modern display drivers like
TIDSS), the bridge's get_modes() is never called. Instead, the
drm_bridge_connector helper calls the bridge's edid_read() and updates the
connector itself. This meant sink_is_hdmi was never populated, causing the
driver to default to DVI mode and breaking HDMI audio.
2. The mode_set() callback doesn't receive atomic state or connector
pointer, making it impossible to check connector->display_info.is_hdmi
directly at that point.
Fix this by moving the HDMI vs DVI decision from mode_set() to
atomic_enable(), where we can access the connector via
drm_atomic_get_new_connector_for_encoder(). This works for both connector
models:
- With DRM_BRIDGE_ATTACH_NO_CONNECTOR: Returns the drm_bridge_connector
created by the display driver, which has already been updated by the
helper's call to drm_edid_connector_update()
- Without DRM_BRIDGE_ATTACH_NO_CONNECTOR (legacy): Returns the connector
embedded in sii902x struct, which gets updated by the bridge's own
get_modes()

The IT66122 is a pin compatible replacement for the IT66122. Based on
empirical testing, the new device looks to be compatible with IT66121.
However due to a lack of public data sheet at this time beyond overall
feature list[1] (which seems to add additional features vs ITT66121),
it is hard to determine that additional register operations required
to enable additional features.
So, introduce the device as a new compatible that we will detect based
on vid/pid match, with explicit id that can be used to extend the
driver capability as information becomes available later on.

The driver knows exactly which version of the chip is present since
the vid/pid is used to enforce a compatibility. Given that some
devices like IT66121 has potentially been replaced with IT66122 mid
production for many platforms, it makes no sense to use the vid/pid
as an enforcement for compatibility. Instead, detect the ID of the
actual chip in use by matching the corresponding vid/pid and drop the
compatible specific lookup table.

Members of struct software_node_ref_args should not be dereferenced
directly but set using the provided macros. Commit d7cdbbc93c56
("software node: allow referencing firmware nodes") changed the name of
the software node member and caused a build failure. Remove all direct
dereferences of the ref struct as a fix.
However, this driver also seems to abuse the software node interface by
waiting for a node with an arbitrary name "intel-xhci-usb-sw" to appear
in the system before setting up the reference for the I2C device, while
the actual software node already exists in the intel-xhci-usb-role-switch
module and should be used to set up a static reference. Add a FIXME for
a future improvement.

All alternatives are disassemble side-by-side when using the --disas
option. However the address of each instruction is not printed because
instructions from different alternatives are not necessarily aligned.
Change this behavior to print the address of each instruction. Spaces
will appear between instructions from the same alternative when
instructions from different alternatives do not have the same alignment.

When using the --disas option, disassemble all group alternatives.
Jump tables and exception tables (which are handled as alternatives)
are not disassembled at the moment.

When using the --disas option, objtool doesn't currently disassemble
any alternative. Print an header for each alternative. This identifies
places where alternatives are present but alternative code is still
not disassembled at the moment.

Preserve the order in which alternatives are defined. Currently
objtool stores alternatives in a list in reverse order.

Add the --disas=<function-pattern> actions to disassemble the specified
functions. The function pattern can be a single function name (e.g.
--disas foo to disassemble the function with the name "foo"), or a shell
wildcard pattern (e.g. --disas foo* to disassemble all functions with a
name starting with "foo").

The .return_sites and .call_sites sections reference text addresses,
but not with the intent to indirect branch to them, so they don't
need to be validated for IBT.
This is useful when running objtool on object files which already
have .return_sites or .call_sites sections, for example to re-run
objtool after it has reported an error or a warning.
