git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"The most interesting aspect is that we now have initial support for
the Apple pin controller as used in the M1 laptops and the iPhones
which is a step forward for using Linux efficiently on this Apple
silicon.
Core changes:
- Add infrastructure for per-parent interrupt data to support the
Apple pin controller.
New drivers:
- New combined pin control and GPIO driver for the Apple SoC. This is
used in all modern Apple silicon such as the M1 laptops but also in
at least recent iPhone variants.
- New subdriver for the Qualcomm SM6350
- New subdriver for the Qualcomm QCM2290
- New subdriver for the Qualcomm PM6350
- New subdriver for the Uniphier NX1
- New subdriver for the Samsung ExynosAutoV9
- New subdriver for the Mediatek MT7986
- New subdriver for the nVidia Tegra194
Improvements:
- Improve power management in the Mediatek driver.
- Improvements to the Renesas internal consistency checker.
- Convert the Rockchip pin control device tree bindings to YAML.
- Finally convert the Qualcomm PMIC SSBI and SPMI MPP GPIO driver to
use hierarchical interrupts.
- Convert the Qualcomm PMIC MPP device tree bindings to YAML"

Pull powerpc updates from Michael Ellerman:
- Enable STRICT_KERNEL_RWX for Freescale 85xx platforms.
- Activate CONFIG_STRICT_KERNEL_RWX by default, while still allowing it
to be disabled.
- Add support for out-of-line static calls on 32-bit.
- Fix oopses doing bpf-to-bpf calls when STRICT_KERNEL_RWX is enabled.
- Fix boot hangs on e5500 due to stale value in ESR passed to
do_page_fault().
- Fix several bugs on pseries in handling of device tree cache
information for hotplugged CPUs, and/or during partition migration.
- Various other small features and fixes.

It is generally unsafe to call put_device() with dpm_list_mtx held,
because the given device's release routine may carry out an action
depending on that lock which then may deadlock, so modify the
system-wide suspend and resume of devices to always drop dpm_list_mtx
before calling put_device() (and adjust white space somewhat while
at it).
For instance, this prevents the following splat from showing up in
the kernel log after a system resume in certain configurations:

This patch extends the DLN2 driver; adding cell for adc_dln2 module.
The original patch[1] fell through the cracks when the driver was added
so ADC has never actually been usable. That patch did not have ACPI
support which was added in v5.9, so the oldest supported version this
current patch can be backported to is 5.10.

The resource_size defines that:
res->end - res->start + 1;
The origin original code is:
sysmgr_config.max_register = res->end - res->start - 3;
So, the correct fix is that:
sysmgr_config.max_register = resource_size(res) - 4;

The Arizona driver has both some devices which only have an I2C
interface and some which only have a SPI interface. Currently both of
these share an of_match table, but this means inapproriate compatibles
are available for each interface. Tidy this up by creating a table for
each interface listing only the appropriate compatibles.

PM8xxx PMIC family uses GPIO as parent IRQ. Using it together with the
irq_set_chained_handler_and_data() results in warnings from the GPIOLIB
(see 461c1a7d4733 ("gpiolib: override irq_enable/disable"))
as in this path the IRQ resources are not allocated (and thus the
corresponding GPIO is not marked as used for the IRQ. Use request_irq so
that the IRQ resources are proprely setup.

Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 14577/77836 datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and charger driver, so using
level sensitive interrupt is here especially important to avoid races.
With an edge configuration in case if first PMIC signals interrupt
followed shortly after by the RTC, the interrupt might not be yet
cleared/acked thus the second one would not be noticed.

The intel_pmt driver shows up as a compile option for all arches but is
32-bit and 64-bit x86 specific.
Add a CONFIG dependency on X86 for intel_pmt.

The mii ioctls are now handled by the ndo_eth_ioctl() callback,
not the old ndo_do_ioctl(), but octeontx2-nicvf introduced the
function for the old way.
Move it over to ndo_eth_ioctl() to actually allow calling it from
user space.

The Pericom PI7C9X2G404/PI7C9X2G304/PI7C9X2G303 PCIe switches have an
erratum for ACS P2P Request Redirect behaviour when used in the cut-through
forwarding mode. The recommended work around for this issue is to use the
switch in store and forward mode. The erratum results in packets being
queued and not being delivered upstream, which can be observed as very poor
downstream device performance and/or dropped device-generated
data/interrupts.
Add a fixup so that when enabling or resuming the downstream port we check
if it has enabled ACS P2P Request Redirect, and if so, change the device
(via the upstream port) to use the store and forward operating mode.
