structure this could lead to an out of bounds memory access. Add the

If ec_device_probe() fails, cros_ec_class_release releases memory for the
cros_ec_dev structure. However, because the drvdata was already set,
sub-drivers like cros_ec_typec can still retrieve the stale pointer via the
platform device. This leads to a use-after-free when cros_ec_typec attempts
to access &typec->ec->ec->dev on a device that has already been released.
Move dev_set_drvdata() to ensure that the pointer is only made available
once all initialization steps have succeeded.

AST2700 consists of two interconnected SoC instances, each with its own

Secondary and Tertiary Service Processors (SSP and TSP).
Describe the SSP/TSP address mappings using the standard

Disallow legacy child nodes that are not present on AST2700, including
p2a-control and smp-memram. The latter is unnecessary as software can
access the scratch registers via the SCU syscon.
Also allow the AST2700 SoC0 pin controller to be described as a child

Support for the Motorola EZX phones based on Intel PXA processors was
removed in 2022, but this driver remained present in the tree. As far
as I can tell, the support was never quite functional upstream because
the board files did not actually instantiate the SPI device for the PCAP.
There are still also drivers for the various mfd cells: keys, touchscreen,
regulator and rtc, all of which are obviously orphaned as well but can
be removed separately as the Kconfig dependency now prevents them from
being enabled.

There are board files in-tree that want to request GPIOs from this chip.
They currently rely on the GPIO core's mechanism of matching software
nodes' labels against GPIO controller names. We want to remove this
behavior from the kernel and to this end, we need to associate the
referenced GPIO controller with its target software node.
Create a dedicated GPIO software node for cs5535, assign it to the GPIO
cell and expose its address in a new header.
We only expose a single software node instance but that's alright: all
existing hardware only contains a single cs5535 companion and the geode
board file for which we expose this is legacy anyway.

The various struct pci_device_id arrays were initialized mostly by one
of the PCI_DEVICE macros and then list expressions. The latter isn't
easily readable if you're not into PCI. Using named initializers is more
explicit and thus easier to parse.
The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on

When platform_device_register() fails in sm501_register_device(), the
embedded struct device in pdev has already been initialized by
device_initialize(), but the failure path only reports the error and
returns without dropping the device reference for the current platform
device:
sm501_register_device()
-> platform_device_register(pdev)
-> device_initialize(&pdev->dev)
-> setup_pdev_dma_masks(pdev)
-> platform_device_add(pdev)
This leads to a reference leak when platform_device_register() fails.
Fix this by calling platform_device_put() before returning the error.
The issue was identified by a static analysis tool I developed and
confirmed by manual review.

Currently, the TPS65219 driver unconditionally registers a poweroff
handler. This causes issues on systems where a different component
(such as TF-A firmware) should handle system poweroff instead.
Make the poweroff handler registration conditional based on the
"system-power-controller" device tree property. This follows the
standard kernel pattern where only the designated power controller
registers for system poweroff operations.
On systems where the property is absent, the PMIC will not register
a poweroff handler, allowing other poweroff mechanisms to function.

Since v2025.11.22:
Initial SoC Slider support
SoC Slider is an SoC-wide power/performance policy setting.
On SoC Slider systems, EPP plays a diminished role.
Whitespace cleanup via: indent -npro -kr -i8 -ts8 -sob -l160 -ss -ncs -cp1
No functional changes
Signed-off-by: Len Brown <len.brown@intel.com>
x86_energy_perf_policy accesses the SoC Slider via standard
user/kernel APIs to the processor_thermal_soc_slider driver.
Machines that support SoC Slider largely use it instead of EPP,
which may continue to exist in a diminished role, or vanish entirely.
Signed-off-by: Len Brown <len.brown@intel.com>
When processor_thermal_soc_slider is loaded, its slider
and offset modparams are visible. Check that the driver
actually registered the profile named "SoC Slider" before
reading or writing these modparams.
n.b. This utility allows writing the Slider and Offset modparams
even if the driver policy is not "balanced". Currently the
processor_thermal_soc_slider consults those modparams
only in "balanced" mode.

On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.
Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.
