If requested_clk > 128, cdns_mrvl_xspi_setup_clock() iterates over the
entire cdns_mrvl_xspi_clk_div_list array without breaking out early,
causing 'i' to go beyond the array bounds.
Fix that by stopping the loop when it gets to the last entry, clamping
the clock to the minimum 6.25 MHz.

Instead of logging the dram type in the per version/platform function,
do it in the generic one. This fixes a few discrepancies depending on
the platform:
- There was no DRAM type logging for graphics version 12 and
above
- For graphics version 11, it would log the DRAM type in
skl_get_dram_info(), but could possibly override it later
without any log in icl_pcode_read_mem_global_info()
For bxt_get_dram_info(), there's no need to log the type for each dimm,
as the drm_WARN_ON() already covers the case they are not all the same.
This maintains the behavior of skl_get_dram_info() that would log the
DRAM type even on failures.

invalid
Prior to commit 496121c02127 ("ACPI: processor: idle: Allow probing on
platforms with one ACPI C-state"), the acpi_idle driver wouldn't load on
systems without a valid C-State at least as deep as C2.
The behavior was desirable for guests on hypervisors such as VMWare
ESXi, which by default don't have the _CST ACPI method, and set the C2
and C3 latencies to 101 and 1001 microseconds respectively via the FADT,
to signify they're unsupported.
Since the above change though, these virtualized deployments end up
loading acpi_idle, and thus entering the default C1 C-State set by
acpi_processor_get_power_info_default(); this is undesirable for a
system that's communicating to the OS it doesn't want C-States (missing
_CST, and invalid C2/C3 in FADT).
Make acpi_processor_get_power_info_fadt() return -ENODEV in that case,
so that acpi_processor_get_cstate_info() exits early and doesn't set
pr->flags.power = 1.

MediaTek MT8188 SoC has an ARM Mali-G57 MC3 GPU (Valhall-JM), which
constantly faults with the current panfrost support.
For instance, running `glmark2-es2-drm` benchmark test:
```
[ 79.617461] panfrost 13000000.gpu: js fault, js=1, status=JOB_BUS_FAULT, head=0xaadc380, tail=0xaadc380

[ 80.129083] access type 0x1: EXECUTE
[ 80.129083] source id 0x0
```
Note that current panfrost mode (Mali LPAE - LEGACY) only allows to
specify write-cache or implementation-defined as the caching policy,
probably not matching the right configuration. As depicted in the source
code:
drivers/iommu/io-pgtable-arm.c:
```
* MEMATTR: Mali has no actual notion of a non-cacheable type, so the
* best we can do is mimic the out-of-tree driver and hope that the
* "implementation-defined caching policy" is good enough...
```
Now that Panfrost supports AARCH64_4K page table format, let's enable it
on Mediatek MT8188 and configure the cache/shareability policies
properly.

Currently, Panfrost only supports MMU configuration in "LEGACY" (as
Bifrost calls it) mode, a (modified) version of LPAE "Large Physical
Address Extension", which in Linux we've called "mali_lpae".
This commit adds support for conditionally enabling AARCH64_4K page
table format. To achieve that, a "GPU optional quirks" field was added
to `struct panfrost_features` with the related flag.
Note that, in order to enable AARCH64_4K mode, the GPU variant must have
the HW_FEATURE_AARCH64_MMU feature flag present.

The I3C master driver may receive an IBI from a target device that has not
been probed yet. In such cases, the master calls `i3c_master_queue_ibi()`
to queue an IBI work task, leading to "Unable to handle kernel read from
unreadable memory" and resulting in a kernel panic.
Typical IBI handling flow:
1. The I3C master scans target devices and probes their respective drivers.
2. The target device driver calls `i3c_device_request_ibi()` to enable IBI
and assigns `dev->ibi = ibi`.
3. The I3C master receives an IBI from the target device and calls
`i3c_master_queue_ibi()` to queue the target device driver’s IBI
handler task.
However, since target device events are asynchronous to the I3C probe
sequence, step 3 may occur before step 2, causing `dev->ibi` to be `NULL`,
leading to a kernel panic.
Add a NULL pointer check in `i3c_master_queue_ibi()` to prevent accessing
an uninitialized `dev->ibi`, ensuring stability.

For platforms that always use VRR Timing Generator, the VTOTAL.Vtotal
bits are not required. Since the support for these bits is going to
be deprecated in upcoming platforms, avoid writing these bits for the
platforms that do not use legacy Timing Generator.

git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Extract the 'pin-init' API from the 'kernel' crate and make it into
a standalone crate.
In order to do this, the contents are rearranged so that they can
easily be kept in sync with the version maintained out-of-tree that
other projects have started to use too (or plan to, like QEMU).
This will reduce the maintenance burden for Benno, who will now
have his own sub-tree, and will simplify future expected changes
like the move to use 'syn' to simplify the implementation.
- Add '#[test]'-like support based on KUnit.
We already had doctests support based on KUnit, which takes the
examples in our Rust documentation and runs them under KUnit.
Now, we are adding the beginning of the support for "normal" tests,
similar to those the '#[test]' tests in userspace Rust. For
instance:
#[kunit_tests(my_suite)]
mod tests {
#[test]
fn my_test() {
assert_eq!(1 + 1, 2);
}
}
Unlike with doctests, the 'assert*!'s do not map to the KUnit
assertion APIs yet.
- Check Rust signatures at compile time for functions called from C
by name.
In particular, introduce a new '#[export]' macro that can be placed
in the Rust function definition. It will ensure that the function
declaration on the C side matches the signature on the Rust
function:
#[export]
pub unsafe extern "C" fn my_function(a: u8, b: i32) -> usize {
// ...
}
The macro essentially forces the compiler to compare the types of
the actual Rust function and the 'bindgen'-processed C signature.
These cases are rare so far. In the future, we may consider
introducing another tool, 'cbindgen', to generate C headers
automatically. Even then, having these functions explicitly marked
may be a good idea anyway.
- Enable the 'raw_ref_op' Rust feature: it is already stable, and
allows us to use the new '&raw' syntax, avoiding a couple macros.
After everyone has migrated, we will disallow the macros.
- Pass the correct target to 'bindgen' on Usermode Linux.
- Fix 'rusttest' build in macOS.
'kernel' crate:
- New 'hrtimer' module: add support for setting up intrusive timers
without allocating when starting the timer. Add support for
'Pin<Box<_>>', 'Arc<_>', 'Pin<&_>' and 'Pin<&mut _>' as pointer
types for use with timer callbacks. Add support for setting clock
source and timer mode.
- New 'dma' module: add a simple DMA coherent allocator abstraction
and a test sample driver.
- 'list' module: make the linked list 'Cursor' point between
elements, rather than at an element, which is more convenient to us
and allows for cursors to empty lists; and document it with
examples of how to perform common operations with the provided
methods.
- 'str' module: implement a few traits for 'BStr' as well as the
'strip_prefix()' method.
- 'sync' module: add 'Arc::as_ptr'.
- 'alloc' module: add 'Box::into_pin'.
- 'error' module: extend the 'Result' documentation, including a few
examples on different ways of handling errors, a warning about
using methods that may panic, and links to external documentation.
'macros' crate:
- 'module' macro: add the 'authors' key to support multiple authors.
The original key will be kept until everyone has migrated.
Documentation:
- Add error handling sections.
MAINTAINERS:
- Add Danilo Krummrich as reviewer of the Rust "subsystem".

Move away from using deprecated API and use _multi variants
if available. Use mipi_dsi_msleep() and mipi_dsi_usleep_range()
instead of msleep() and usleep_range() respectively.
Used Coccinelle to find the _multi variant APIs,replacing
mpi_dsi_msleep() where necessary and for returning
dsi_ctx.accum_err in these functions. mipi_dsi_dcs_write()
does not have a corresponding _multi() variant. Replacing it with
mipi_dsi_dcs_write_seq_multi() instead. This change is manual.
The Coccinelle script is the same as the one in commit c8ba07caaecc
("drm/panel/synaptics-r63353: Use _multi variants")
v2: Use mipi_dsi_write_buffer_multi() in place of
mipi_dsi_dcs_write(). (Dmitry)
v3: add commit details where the same coccinelle script is
used and remove the actual script from commit log.
Use mipi_dsi_dcs_write_seq_multi() for mipi_dsi_dcs_write() (Doug)

At present, the DSI mode configuration check happens during the
_atomic_enable() phase, which is not really the best place for this.
Moreover, if the mode is not valid, the driver gives a warning and
continues the hardware configuration.
Move the DSI mode configuration check to _atomic_check() instead, which
can properly report back any invalid mode, before the _enable phase even
begins.

Once the DSI Link and DSI Phy are initialized, the code needs to wait
for Clk and Data Lanes to be ready, before continuing configuration.
This is in accordance with the DSI Start-up procedure, found in the
Technical Reference Manual of Texas Instrument's J721E SoC[0] which
houses this DSI TX controller.
If the previous bridge (or crtc/encoder) are configured pre-maturely,
the input signal FIFO gets corrupt. This introduces a color-shift on the
display.
Allow the driver to wait for the clk and data lanes to get ready during
DSI enable.

The crtc_* mode parameters do not get generated (duplicated in this
case) from the regular parameters before the mode validation phase
begins.
The rest of the code conditionally uses the crtc_* parameters only
during the bridge enable phase, but sticks to the regular parameters
for mode validation. In this singular instance, however, the driver
tries to use the crtc_clock parameter even during the mode validation,
causing the validation to fail.
Allow the D-Phy config checks to use mode->clock instead of
mode->crtc_clock during mode_valid checks, like everywhere else in the
driver.

The driver code doesn't have a Phy de-initialization path as yet, and so
it does not clear the phy_initialized flag while suspending. This is a
problem because after resume the driver looks at this flag to determine
if a Phy re-initialization is required or not. It is in fact required
because the hardware is resuming from a suspend, but the driver does not
carry out any re-initialization causing the D-Phy to not work at all.
Call the counterparts of phy_init() and phy_power_on(), that are
phy_exit() and phy_power_off(), from _bridge_post_disable(), and clear
the flags so that the Phy can be initialized again when required.

Fix the OF node pointer passed to the of_drm_find_bridge() call to find
the next bridge in the display chain.
The code to find the next panel (and create its panel-bridge) works
fine, but to find the next (non-panel) bridge does not.
To find the next bridge in the pipeline, we need to pass "np" - the OF
node pointer of the next entity in the devicetree chain. Passing
"of_node" to of_drm_find_bridge (which is what the code does currently)
will fetch the bridge for the cdns-dsi which is not what's required.
Fix that.

"Here's the pile of clk driver patches. The usual suspects^Wsilicon
vendors are all here, adding new SoC support and fixing existing code.
There are a few patches to the clk framework here as well. They've
been baking in linux-next for weeks so I'm hoping we don't have to
revert them. The disable OF node patch is probably the scariest one
although it seems unlikely that a system would be relying on a driver
_not_ probing because the clk never appeared, but you never know.
Nothing looks out of the ordinary on the driver side but that's
because it's mostly a bunch of data.
Core:
- Use dev_err_probe() in the clk registration path (Peering into the
crystal ball shows many patches that remove printks)
- Check for disabled OF nodes in of_clk_get_hw_from_clkspec()

Pull LED updates from Lee Jones:
- pca955x: Add HW blink support, utilizing PWM0. It supports one
frequency across all blinking LEDs and falls back to software blink
if different frequencies are requested.
- trigger: netdev: Allow configuring LED blink interval via .blink_set
even when HW offload (.hw_control) is enabled.
- led-core: Fix a race condition where a quick LED_OFF followed by
another brightness set could leave the LED off incorrectly,
especially noticeable after the introduction of the ordered
workqueue.
- qcom-lpg: Add support for 6-bit PWM resolution alongside the existing
9-bit support.
- qcom-lpg: Fix PWM value capping to respect the selected resolution
(6-bit or 9-bit) for normal PWMs.
- qcom-lpg: Fix PWM value capping to respect the selected resolution
for Hi-Res PWMs.
- qcom-lpg: Fix calculation of the best period for Hi-Res PWMs to
prevent requested duty cycles from exceeding the maximum allowed by
the selected resolution.
- st1202: Add a check for the error code returned by devm_mutex_init().
- pwm-multicolor: Add a check for the return value of
fwnode_property_read_u32().
- st1202: Ensure hardware initialization (st1202_setup) happens before
DT node processing (st1202_dt_init).
- Kconfig: leds-st1202: Add select LEDS_TRIGGER_PATTERN as it's
required by the driver.
- lp8860: Drop unneeded explicit assignment to REGCACHE_NONE.
- pca955x: Refactor code with helper functions and rename some
functions/variables for clarity.
- pca955x: Pass driver data pointers instead of the I2C client to
helper functions.
- pca955x: Optimize probe LED selection logic to reduce I2C operations.
- pca955x: Revert the removal of pca95xx_num_led_regs() (renaming it to
pca955x_num_led_regs) as it's needed for HW blink support.
- st1202: Refactor st1202_led_set() to use the !! operator for boolean
conversion.
- st1202: Minor spacing and proofreading edits in comments.
- Directory Rename: Rename the drivers/leds/simple directory to
drivers/leds/simatic as the drivers within are not simple.
- mlxcpld: Remove unused include of acpi.h.
- nic78bx: Tidy up the ACPI ID table (remove ACPI_PTR, use
mod_devicetable.h, remove explicit driver_data initializer).
- tlc591xx: Convert text binding to YAML format, add child node
constraints, and fix typos/formatting in the example.
- qcom-lpg: Document the qcom,pm8937-pwm compatible string as a
fallback for qcom,pm8916-pwm.
