60ac35bf6b Merge tag 'irq-core-2022-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull interrupt updates from Thomas Gleixner:
 "Core code:

   - Provide a generic wrapper which can be utilized in drivers to
     handle the problem of force threaded demultiplex interrupts on RT
     enabled kernels. This avoids conditionals and horrible quirks in
     drivers all over the place

   - Fix up affected pinctrl and GPIO drivers to make them cleanly RT
     safe

  Interrupt drivers:

   - A new driver for the FSL MU platform specific MSI implementation

   - Make irqchip_init() available for pure ACPI based systems

   - Provide a functional DT binding for the Realtek RTL interrupt chip

   - The usual DT updates and small code improvements all over the
     place"

   - reference the properties from the SPI peripheral device-tree
     bindings instead of providing custom ones in the GPIO controller
     document
   - add parsing of GPIO hog nodes to the DT bindings for gpio-mpfs-gpio
   - relax the node name requirements in gpio-stmpe
   - add new models for gpio-rcar and gpio-pxa95xx

  Misc:
   - pulled in the immutable branch from the x86 platform drivers tree
     including support for a new simatic board that depends on GPIO
     changes"

The ACPI spec defines the SharedAndWake and ExclusiveAndWake share type
keywords. This is an indication that the GPIO IRQ can also be used as a
wake source. This change exposes the wake_capable bit so drivers can
correctly enable wake functionality instead of making an assumption.

8ea8af6c84 gpio: rockchip: request GPIO mux to pinctrl when setting direction
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.

Add fdinfo output for file descriptors created for user-space line
requests in GPIO uAPI v2. The fdinfo file now contains the name of the
GPIO chip that is the "parent" of the request as well as offsets of
the lines requested. This allows user-space to parse the /proc/$PID/fdinfo
entries and deduce the PID of the process that requested a specific line.

69bef19d6b gpiolib: cdev: Set lineevent_state::irq after IRQ register successfully
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.

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.

9714791154 gpio: twl4030: Reorder functions which allows to drop a forward declaraion
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.

8b10ca2f75 gpiolib: fix OOB access in quirk callbacks
Commit a2b5e207ca ("gpiolib: rework quirk handling in of_find_gpio()")
introduced an array of quirk functions which get iterated over. But a
sentinal value is missing. Add it.

118c3ba24d gpio: mlxbf2: Use generic_handle_irq_safe()
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().
