Pull gpio updates from Bartosz Golaszewski:
"There's one new driver, lots of various updates to existing ones, some
refactoring support for new models and misc tweaks and fixes.
The biggest new feature in GPIO core is adding support for managed,
enable-counted sharing of GPIO pins, something that - until now - was
only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
which basically allowed drivers to "fight it out" for the descriptor
and provided no synchronization. It was enabled on Qualcomm platforms
(and thus is enabled on arm64 defconfig) and I plan on removing
GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
the new mechanism.
GPIO core:
- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot
enable counting) and enable it for Qualcomm platforms
- improve the software node GPIO lookup by using the fwnode
representation instead of the software node's name which was prone
to bugs (GPIO controllers don't have to use the software node's
name as their kernel label)
- remove the last user of legacy-of-mm-gpiochip.h and drop the header
- move closer to removing the legacy gpio_request_one() routine
- rename some symbols for consistency
- shrink GPIO printk() helpers by reusing existing code
- remove some redundant kernel messages
- use min() instead of min_t() in GPIO ACPI code
- use system_percpu_wq instead of system_wq in GPIO character device
code
New drivers:
- add a driver for the QIXIS FPGA GPIO controller
Driver improvements:
- use modernized variants of power management macros across a wide
array of drivers in order to avoid having to use the __maybe_unused
attribute
- convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
instead of the platform bus as they are not really described in
firmware
- use lock guards and update symbol prefixes in gpio-mmio
- support the bryx radio interface kit in gpio-mpsse + refactor the
driver
- use software nodes for configuring the reset-gpio driver, including
setting up the reference to the shared "reset" pin
- check and propagate the return value of gpiod_set_value() to
user-space in gpio-virtuser (this was previously not possible as
this function returned void)
- extend the gpio-regmap helper with more features (bypass cache for
aliased inputs, force writes for aliased data registers, add a new
configuration parameter)
- remove unneeded includes from gpio-aspeed and gpio-latch
- add support for Tegra410 to gpio-tegra186
- replace PCI-specific PM with generic device-level PM in gpio-bt8xx
- use dynamic GPIO range allocation in gpio-loongson-64bit
- improve handling of level-triggered interrupts in gpio-pca953x
- add suspend/resume support to gpio-fxl6408
- add support for more models to gpio-menz127
- optimize gpio-mvebu interrupt handling by avoiding unnecessary
calls to mvebu_gpio_irq_handler()
- make locking more consistent in gpio-grgpio
Device-tree bindings:
- document new NXP and Microchip models
Documentation:
- add a comprehensive compatibility and feature list for
gpio-pca953x, which is a great addition as it's probably the most
commonly used GPIO expander driver
- kernel-doc tweaks
Late fixes:
- use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson"

Dell Pro Rugged 10/12 tablets has a reliable VGBS method.
If VGBS is not called on boot, the on-screen keyboard won't appear if the
device is booted without a keyboard.
Call VGBS on boot on thess devices to get the initial state of
SW_TABLET_MODE in a reliable way.

This passes the address of the pointer "&punit_ipcdev" when the intent
was to pass the pointer itself "punit_ipcdev" (without the ampersand).
This means that the:
complete(&ipcdev->cmd_complete);
in intel_punit_ioc() will write to a wrong memory address corrupting it.

Reset/GPIO/swnode changes for v6.19 (v2)
* Fix chtwc_int33fe build issue since commit d7cdbbc93c56 ("software
node: allow referencing firmware nodes").
|
|
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.

Intel Elkhart Lake Programmable Service Engine (PSE) includes two PCI
devices that expose two different capabilities of GPIO and Timed I/O
as a single PCI function through shared MMIO with below layout.
GPIO: 0x0000 - 0x1000
TIO: 0x1000 - 0x2000
This driver enumerates the PCI parent device and creates auxiliary child
devices for these capabilities. The actual functionalities are provided
by their respective auxiliary drivers.

regulator_unregister() already frees the associated GPIO device. On
ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to
random failures when other drivers (typically Intel THC) attempt to
allocate interrupts. The root cause is that the reference count of the
pinctrl_intel_platform module unexpectedly drops to zero when this
driver defers its probe.
This behavior can also be reproduced by unloading the module directly.
Fix the issue by removing the redundant release of the GPIO device
during regulator unregistration.

Relocate the lpm_req_guid field from pmc_info to pmc_reg_map. The
previous implementation stored lpm_req_guid in pmc_info and relied

Replace dev_warn() with dev_dbg() to reduce unnecessary warning messages.
When the low power mode priority register contains invalid data, the Intel
PMC Core driver can still utilize the default priority list. This scenario
is more suited for debug information rather than warning.

This model was added as INTEL_PANTHERCOVE_X (based on the name of the
core) with a comment that the platform name is Diamond Rapids. It was
also placed at the end of the file in a new section for family 19
processors.
This is different from previous naming as Andrew Cooper noted.
PeterZ agreed and posted a patch[1] to fix the name and move it in
sequence with other Xeon servers. But without a commit description or
sign-off the patch wasn't ever applied.
Patch updated to cover one additional use of the #define by turbostat
and to change the "Family 6" comment to also list 18 and 19 since new
models in these families are mixed in with family 6.

In partitioned systems, the domain ID is unique in the partition and a
package can have multiple partitions.
Some user-space tools, such as turbostat, assume the domain ID is unique
per package. These tools map CPU power domains, which are unique to a
package. However, this approach does not work in partitioned systems.
There is no architectural definition of "partition" to present to user
space.
To support these tools, set the domain_id to be unique per package. For
compute die IDs, uniqueness can be achieved using the platform info
cdie_mask, mirroring the behavior observed in non-partitioned systems.
For IO dies, which lack a direct CPU relationship, any unique logical
ID can be assigned. Here domain IDs for IO dies are configured after all
compute domain IDs. During the probe, keep the index of the next IO
domain ID after the last IO domain ID of the current partition. Since
CPU packages are symmetric, partition information is same for all
packages.
The Intel Speed Select driver has already implemented a similar change
to make the domain ID unique, with compute dies listed first, followed
by I/O dies.

package ID
Currently, tpmi_get_logical_id() calls topology_physical_package_id()
to set the pkg_id of the info structure. Since some VM hosts assign non
contiguous package IDs, topology_physical_package_id() can return a
larger value than topology_max_packages(). This will result in an
invalid reference into tpmi_power_domain_mask[] as that is allocatead
based on topology_max_packages() as the maximum package ID.

Replace devm_kzalloc() with devm_kcalloc() in pmc_core_get_tgl_lpm_reqs().
As noted in the kernel documentation [1], open-coded multiplication in
allocator arguments is discouraged because it can lead to integer
overflow.
Using devm_kcalloc() provides built-in overflow protection, making the
memory allocation safer when calculating the allocation size compared
to explicit multiplication.

A partitioned system configured with only one package and one compute
die, warning will be generated for duplicate sysfs entry. This typically
occurs during the platform bring-up phase.
Partitioned systems expose dies, equivalent to TPMI compute domains,
through the CPUID. Each partitioned system must contains at least one
compute die per partition, resulting in a minimum of two dies per
package. Hence the function topology_max_dies_per_package() returns at
least two, and the condition "topology_max_dies_per_package() > 1"
prevents the creation of a root domain.
In this case topology_max_dies_per_package() will return 1 and root
domain will be created for partition 0 and a duplicate sysfs warning
for partition 1 as both partitions have same package ID.
To address this also check for non zero partition in addition to
topology_max_dies_per_package() > 1.

On HP laptops with an ov08x40 sensor the 25 ms delay coming from Intel's
out of tree drivers is not enough. Testing has confirmed that 45 ms does
work.
Add a quirk to the int3472_gpio_map[] to increase the delay to 45 ms to fix
probing of the ov08x40 sensor failing on these laptops.
Note this only impacts laptops which actually use an ov08x40 sensor with
a handshake GPIO.
