Merge tag 'pinctrl-v5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
"There is a lot going on!

Core changes:

- A semantic change to handle pinmux and pinconf in explicit order
while up until now we depended on the semantic order in the device
tree. The device tree is a functional programming language and does
not imply any order, so the right thing is for the pin control core
to provide these semantics.

- Add a new pinmux-select debugfs file which makes it possible to go
in and select functions for a pin manually (iteratively, at the
prompt) for debugging purposes.

- Fixes to gpio regmap handling for a new pin control driver making
use of regmap-gpio.

- Use octal permissions on debugfs files.

New drivers:

- A massive rewrite of the former custom pin control driver for MIPS
Broadcom devices to instead use the pin control subsystem. New pin
control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368,
BCM63268 and BCM6318 SoC variants are implemented.

- Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B
in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are
supported.

- Support for the Rockchip RK3568/RK3566 pin controller.

- Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000.

- Support for Mediatek MTK8195.

- Add a new Xilinx ZynqMP pin control driver.

Driver improvements and non-urgent fixes:

- Modularization and improvements of the Rockchip drivers.

- Some new pins added to the description of new Renesas SoCs.

- Clarifications of the GPIO base calculation in the Intel driver.

- Fix the function names for the MPP54 and MPP55 pins in the Armada
CP110 pin controller.

- GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.

- Support for ACPI probing of the Qualcomm SC8180x.

- Fix interrupt clear status on rockchip

- Fix some missing pins on the Ingenic JZ4770, some semantic fixes
for the behaviour of the Ingenic pin controller. Add DMIC pins for
JZ4780, X1000, X1500 and X1830.

- A slew of janitorial like of_node_put() calls"

gpio: regmap: set gpio_chip of_node

2021-03-29T10:20:07+00:00

This is needed for properly registering GPIO regmap as a child of a regmap
pin controller.

gpio: guard gpiochip_irqchip_add_domain() with GPIOLIB_IRQCHIP

2021-03-29T10:20:07+00:00

The current code doesn't check if GPIOLIB_IRQCHIP is enabled, which results in
a compilation error when trying to build gpio-regmap if CONFIG_GPIOLIB_IRQCHIP
isn't enabled.

gpiolib: acpi: Add ACPI_GPIO_QUIRK_ABSOLUTE_NUMBER quirk

2021-03-08T10:59:17+00:00

On some systems the ACPI tables has wrong pin number and instead of
having a relative one it provides an absolute one in the global GPIO
number space.

Add ACPI_GPIO_QUIRK_ABSOLUTE_NUMBER quirk to cope with such cases.

gpio: aggregator: Use compound literal from the header

2021-02-15T10:43:32+00:00

Instead of doing it in place, convert GPIO_LOOKUP_IDX() and GPIO_HOG()
to be compund literals that's allow to use them as rvalue in assignments.

Due to above conversion, use compound literal from the header
in the gpio-aggregator.c.

gpio: Retire the explicit gpio irqchip code

2020-10-28T14:50:06+00:00

Now that all gpiolib irqchip users have been over to use
the irqchip template, we can finally retire the old code
path and leave just one way in to the irqchip: set up the
template when registering the gpio_chip. For a while
we had two code paths for this which was a bit confusing.

This brings this work to a conclusion, there is now one
way of doing this.

gpiolib: unexport devprop_gpiochip_set_names()

2020-09-14T08:54:42+00:00

Now that devprop_gpiochip_set_names() is only used in a single place
inside drivers/gpio/gpiolib.c, there's no need anymore for it to be
exported or to even live in its own source file. Pull this function into
the core source file for gpiolib.
