Merge tag 'pinctrl-v5.6-1' 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, nothing too exciting about
this.

Some changes hit arch/sh and arch/arm but are well isolated and
acknowledged by the respective arch maintainers.

Core changes:

- Dropped the chained IRQ setup callback into GPIOLIB as we got rid
of the last users of that in this changeset.

New drivers:

- New driver for Ingenic X1830.

- New driver for Freescale i.MX8MP.

Driver enhancements:

- Fix all remaining Intel drivers to pass their IRQ chips along with
the GPIO chips.

- Intel Baytrail allocates its irqchip dynamically.

- Intel Lynxpoint is thoroughly rewritten and modernized.

- Aspeed AST2600 pin muxing and configuration is much improved.

- Qualcomm SC7180 functions are updated and wakeup interrupt map is
provided.

- A whole slew of Renesas SH-PFC cleanups and improvements.

- Fix up the Intel DT bindings to use the generic YAML DT bindings
schema (a first user of this)"

pinctrl: iproc: Use platform_get_irq_optional() to avoid error message

2020-01-15T12:46:11+00:00

Use platform_get_irq_optional() instead of platform_get_irq() to avoid
below error message during probe:

[ 0.589121] iproc-gpio 66424800.gpio: IRQ index 0 not found

remove ioremap_nocache and devm_ioremap_nocache

2020-01-06T08:45:59+00:00

ioremap has provided non-cached semantics by default since the Linux 2.6
days, so remove the additional ioremap_nocache interface.

pinctrl: iproc: Set irq handler based on trig type

2019-12-16T09:43:26+00:00

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.

pinctrl: use devm_platform_ioremap_resource() to simplify code

2019-11-05T14:33:40+00:00

devm_platform_ioremap_resource() internally have platform_get_resource()
and devm_ioremap_resource() in it. So instead of calling them separately
use devm_platform_ioremap_resource() directly.

pinctrl: bcm: nsp: implement get_direction

2019-11-04T15:20:38+00:00

The get_direction api is strongly recommended to be implemented. In fact
if it is not implemented gpio-hogs will not get the correct direction.
Add an implementation of get_direction for the nsp-gpio driver.

pinctrl: bcm: nsp: use gpiolib infrastructure for interrupts

2019-11-04T15:19:44+00:00

Use more of the gpiolib infrastructure for handling interrupts. The
root interrupt still needs to be handled manually as it is shared with
other peripherals on the SoC.

This will allow multiple instances of this driver to be supported and
will clean up gracefully on failure thanks to the device managed APIs.

pinctrl: iproc: allow for error from platform_get_irq()

2019-10-05T16:36:57+00:00

platform_get_irq() can return an error code. Allow for this when getting
the irq.

pinctrl: iproc: use unique name for irq chip

2019-10-05T16:36:30+00:00

Use the dev_name(dev) for the irqc->name so that we get unique names
when we have multiple instances of this driver.
