[ Upstream commit 513034d8b089b9a49dab57845aee70e830fe7334 ]

When PINCTRL_BCM2835 is enabled and GPIOLIB is disabled, it results in the
following Kbuild warning:

WARNING: unmet direct dependencies detected for GPIOLIB_IRQCHIP
Depends on [n]: GPIOLIB [=n]

- PINCTRL_BCM2835 [=y] && PINCTRL [=y] && OF [=y] && (ARCH_BCM2835 [=n] || ARCH_BRCMSTB [=n] || COMPILE_TEST [=y])

The reason is that PINCTRL_BCM2835 selects GPIOLIB_IRQCHIP without
depending on or selecting GPIOLIB while GPIOLIB_IRQCHIP is subordinate to
GPIOLIB.

Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

Merge tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.3 kernel cycle:

Core changes:

- Device links can optionally be added between a pin control producer
and its consumers. This will affect how the system power management
is handled: a pin controller will not suspend before all of its
consumers have been suspended.

This was necessary for the ST Microelectronics STMFX expander and
need to be tested on other systems as well: it makes sense to make
this default in the long run.

Right now it is opt-in per driver.

- Drive strength can be specified in microamps. With decreases in
silicon technology, milliamps isn't granular enough, let's make it
possible to select drive strengths in microamps.

Right now the Meson (AMlogic) driver needs this.

New drivers:

- New subdriver for the Tegra 194 SoC.

- New subdriver for the Qualcomm SDM845.

- New subdriver for the Qualcomm SM8150.

- New subdriver for the Freescale i.MX8MN (Freescale is now a product
line of NXP).

- New subdriver for Marvell MV98DX1135.

Driver improvements:

- The Bitmain BM1880 driver now supports pin config in addition to
muxing.

- The Qualcomm drivers can now reserve some GPIOs as taken aside and
not usable for users. This is used in ACPI systems to take out some
GPIO lines used by the BIOS so that noone else (neither kernel nor
userspace) will play with them by mistake and crash the machine.

- A slew of refurbishing around the Aspeed drivers (board management
controllers for servers) in preparation for the new Aspeed AST2600
SoC.

- A slew of improvements over the SH PFC drivers as usual.

- Misc cleanups and fixes"

pinctrl: bcm2835: switch to GPIOLIB_IRQCHIP

It should be possible to use the GPIOLIB_IRQCHIP helper
library with the BCM2835 driver since it is a pretty straight
forward cascaded irqchip.

The only difference from other drivers is that the BCM2835
has several banks for a single gpiochip, and each bank has
a separate IRQ line. Instead of creating one gpiochip per
bank, a single gpiochip covers all banks GPIO lines. This
makes it necessary to resolve the bank ID in the IRQ
handler.

The GPIOLIB_IRQCHIP allows several IRQs to be cascaded off
the same gpiochip by calling gpiochip_set_chained_irqchip()
repeatedly, but we have been a bit short on examples
for how this should be handled in practice, so this is intended
as an example of how this can be achieved.

The old code did not model the chip as a chained interrupt
handler, but this patch also rectifies that situation.
