eebefdd0b7 pinctrl: bcm: Add missing header(s)
Do not imply that some of the generic headers may be always included.
Instead, include explicitly what we are direct user of.

While at it, sort headers alphabetically.

08752e0749 pinctrl: bcm2835: Make the irqchip immutable
Commit 6c846d026d ("gpio: Don't fiddle with irqchips marked as
immutable") added a warning to indicate if the gpiolib is altering the
internals of irqchips. The bcm2835 pinctrl is also affected by this
warning.

Fix this by making the irqchip in the bcm2835 pinctrl driver immutable.

db1b3ecee9 pinctrl: bcm2835: drop irq_enable/disable callbacks
The commit b8a19382ac ("pinctrl: bcm2835: Fix support for threaded level
triggered IRQs") assigned the irq_mask/unmask callbacks with the
already existing functions for irq_enable/disable. The wasn't completely
the right way (tm) to fix the issue, because these callbacks shouldn't
be identical. So fix this by rename the functions to represent their
intension and drop the unnecessary irq_enable/disable assigment.

The commit c8013355ea ("ARM: dts: gpio-ranges property is now required")
fixed the GPIO probing issues caused by "pinctrl: bcm2835: Change init

it isn't guaranteed that these files are shipped to all users.

So implement the necessary backward compatibility for BCM2835 and

When PINCTRL_BCM63XX is selected,
and REGMAP is not selected,
Kbuild gives the following warning:

  Depends on [n]: GPIOLIB [=y] && REGMAP [=n]
  Selected by [y]:
  - PINCTRL_BCM63XX [=y] && PINCTRL [=y]

This is because PINCTRL_BCM63XX
selects GPIO_REGMAP without selecting or depending on
REGMAP, despite GPIO_REGMAP depending on REGMAP.

This unmet dependency bug was detected by Kismet,
a static analysis tool for Kconfig. Please advise
if this is not the appropriate solution.

e3084ed48f Pin control bulk changes for the v5.17 kernel cycle
Core changes:
 
 - New standard enumerator and corresponding device tree bindings
   for output impedance pin configuration. (Implemented and used
   in the Renesas rzg2l driver.)
 
 - Cleanup of Kconfig and Makefile to be somewhat orderly and
   alphabetic.
 
 New drivers:
 
 - Samsung Exynos 7885 pin controller.
 
 - Ocelot LAN966x pin controller.
 
 - Qualcomm SDX65 pin controller.
 
 - Qualcomm SM8450 pin controller.
 
 - Qualcomm PM8019, PM8226 and PM2250 pin controllers.
 
 - NXP/Freescale i.MXRT1050 pin controller.
 
 - Intel Thunder Bay pin controller.
 
 Enhancements:
 
 - Introduction of the string library helper function
   "kasprintf_strarray()" and subsequent use in Rockchip, ST and
   Armada pin control drivers, as well as the GPIO mockup driver.
 
 - The Ocelot pin controller has been extensively rewritten to
   use regmap and other modern kernel infrastructure.
 
 - The Microchip SGPIO driver has been converted to use regmap.
 
 - The SPEAr driver had been converted to use regmap.
 
 - Substantial cleanups and janitorial on the Apple pin control
   driver that was merged for v5.16.
 
 - Janitorial to remove of_node assignments in the GPIO portions
   that anyway get this handled in the GPIO core.
 
 - Minor cleanups and improvements in several pin controllers.

266423e60e pinctrl: bcm2835: Change init order for gpio hogs
...and gpio-ranges

pinctrl-bcm2835 is a combined pinctrl/gpio driver. Currently the gpio
side is registered first, but this breaks gpio hogs (which are
configured during gpiochip_add_data). Part of the hog initialisation
is a call to pinctrl_gpio_request, and since the pinctrl driver hasn't
yet been registered this results in an -EPROBE_DEFER from which it can
never recover.

Change the initialisation sequence to register the pinctrl driver
first.

This also solves a similar problem with the gpio-ranges property, which
is required in order for released pins to be returned to inputs.

6dba4bdfd7 Revert "pinctrl: bcm: ns: support updated DT binding as syscon subnode"
This reverts commit a49d784d5a.

The updated binding was wrong / invalid and has been reverted. There
isn't any upstream kernel DTS using it and Broadcom isn't known to use
it neither. There is close to zero chance this will cause regression for
anyone.

Actually in-kernel bcm5301x.dtsi still uses the old good binding and so
it's broken since the driver update. This revert fixes it.

ef9385fbf3 pinctrl: iproc-gpio: Remove redundant error printing in iproc_gpio_probe()
When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource
information.

Therefore, remove the error printing here to simplify code and reduce the
binary size.

Rather than always using handle_simple_irq() as the gpio_irq_chip
handler, set a more appropriate handler based on the IRQ trigger type
requested. This is important for level triggered interrupts which need
to be masked during handling. Also, fix the interrupt acknowledge so
that it clears only one interrupt instead of all interrupts which are
currently active. Finally there is no need to clear the interrupt during
the interrupt handler, since the edge-triggered handler will do that for
us.
