Pull pin control updates from Linus Walleij:
"The two large chunks is the header clean-up from Andy and the Qualcomm
DT bindings clean-up from Krzysztof. Each which could give rise to
conflicts, but I haven't seen any.
The YAML conversions happening around the device tree is the biggest
item in the series and is the result of Rob Herrings ambition to
autovalidate these trees against strict schemas and it is paying off
in lots of bugs found and ever prettier device trees. Sooner or later
the transition will be complete, Krzysztof is fixing up all of the
Qualcomm stuff, which is pretty voluminous.
Core changes:
- minor but nice and important documentation clean-ups
New drivers:
- subdriver for the Qualcomm SDM670 SoC
- subdriver for the Intel Moorefield SoC
- trivial support for the NXP Freescale i.MXRT1170 SoC
Other changes and improvements
- major clean-up of the Qualcomm pin control device tree bindings by
Krzysztof
- major header clean-up by Andy
- some immutable irqchip clean-up for the Actions Semiconductor and
Nuvoton drivers
- GPIO helpers for The Cypress cy8c95x0 driver
- bias handling in the Mediatek MT7986 driver
- remove the unused pins-are-numbered concept that never flew"

for_each_pci_dev() is implemented by pci_get_device(). The comment of
pci_get_device() says that it will increase the reference count for the
returned pci_dev and also decrease the reference count for the input
pci_dev @from if it is not NULL.
If we break for_each_pci_dev() loop with pdev not NULL, we need to call
pci_dev_put() to decrease the reference count. Add the missing
pci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL
input parameter, there is no problem for the 'Device not found' branch.
For the normal path, add pci_dev_put() in amd_gpio_exit().

Here is a backtrace report about memory leak detected in
gpiochip_setup_dev():
unreferenced object 0xffff88810b406400 (size 512):
comm "python3", pid 1682, jiffies 4295346908 (age 24.090s)

gcdev_register() & gcdev_unregister() would call device_add() &
device_del() (no matter CONFIG_GPIO_CDEV is enabled or not) to
register/unregister device.
However, if device_add() succeeds, some resource (like
struct device_private allocated by device_private_init())
is not released by device_del().
Therefore, after device_add() succeeds by gcdev_register(), it
needs to call put_device() to release resource in the error handle
path.
Here we move forward the register of release function, and let it
release every piece of resource by put_device() instead of kfree().
While at it, fix another subtle issue, i.e. when gc->ngpio is equal
to 0, we still call kcalloc() and, in case of further error, kfree()
on the ZERO_PTR pointer, which is not NULL. It's not a bug per se,
but rather waste of the resources and potentially wrong expectation
about contents of the gdev->descs variable.

On i.MX8QM/QXP/DXL SoCs, even a GPIO is selected as the wakeup source,
the GPIO block will be powered off when system enters into suspend
state. This can greatly reduce the power consumption of suspend state
because the whole partition can be shutdown. This is called PAD wakeup
feature on i.MX8x platform.
This patch adds the noirq suspend/resume hooks and uses the pad wakeup
feature as the default wakeup method for GPIO modules on
i.MX8QM/QXP/DXL platforms.

Before the split of gpio and pinctrl sections in their own driver,
rockchip_set_mux was called in pinmux_ops.gpio_set_direction for
configuring a pin in its GPIO function.
This is essential for cases where pinctrl is "bypassed" by gpio
consumers otherwise the GPIO function is not configured for the pin and
it does not work. Such was the case for the sysfs/libgpiod userspace
GPIO handling.
Let's call pinctrl_gpio_direction_input/output when setting the
direction of a GPIO so that the pinctrl core requests from the rockchip
pinctrl driver to put the pin in its GPIO function.

When running gpio test on nxp-ls1028 platform with below command
gpiomon --num-events=3 --rising-edge gpiochip1 25
There will be a warning trace as below:
Call trace:
free_irq+0x204/0x360
lineevent_free+0x64/0x70
gpio_ioctl+0x598/0x6a0
__arm64_sys_ioctl+0xb4/0x100
invoke_syscall+0x5c/0x130
......
el0t_64_sync+0x1a0/0x1a4
The reason of this issue is that calling request_threaded_irq()
function failed, and then lineevent_free() is invoked to release
the resource. Since the lineevent_state::irq was already set, so
the subsequent invocation of free_irq() would trigger the above
warning call trace. To fix this issue, set the lineevent_state::irq
after the IRQ register successfully.

The commit 924610607f ("gpio: tpmx86: Move PM device over to
irq domain") adds a dereference of girq that may be uninitialized.
Fix this by moving irq_domain_set_pm_device into if true branch
as suggested by Marc Zyngier.

We now remove the device's debugfs entries when unbinding the driver.
This now causes a NULL-pointer dereference on module exit because the
platform devices are unregistered *after* the global debugfs directory
has been recursively removed. Fix it by unregistering the devices first.

There is no cyclic dependency between gpio_twl4030_probe() and
gpio_twl4030_remove(), so by moving the latter before the former the
forward declaration can be dropped.

On PREEMPT_RT enabled kernels the demultiplex interrupt handler is force
threaded and runs with interrupts enabled. The invocation of
generic_handle_irq() with interrupts enabled triggers a lockdep warning due
to a non-irq safe lock acquisition.
Instead of disabling interrupts on the driver level, use
generic_handle_domain_irq_safe().

There are several places where we need to convert from OF flags to
"normal" GPIO_* flags, so let's introduce a helper and use it.

There is no need for of_find_spi_cs_gpio() to be different from other
quirks: the only variant of property actually used in DTS is "gpios"
(plural) so we can use of_get_named_gpiod_flags() instead of recursing
into of_find_gpio() again.
This will allow us consolidate quirk handling down the road.

not what the user wants, so utilize the module_isa_driver_with_irq macro
