pinctrl: Use new GPIO_LINE_DIRECTION

2020-02-21T14:19:42+00:00

Use newly added GPIO defines GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT instead of using hard-coded 1 and 0.

Main benefit is to make it easier to see which values mean IN and which
OUT. As a side effect this helps GPIO framework to change the direction
defines to something else if ever needed.

Please note that return value from get_direction call on
pinctrl-axp209 driver was changed. Previously pinctrl-axp209 might have
returned value 2 for direction INPUT.

pinctrl: bcm2835: Add support for all GPIOs on BCM2711

2020-02-14T10:49:28+00:00

The BCM2711 supports 58 GPIOs. So extend pinctrl and GPIOs accordingly.

pinctrl: bcm2835: Refactor platform data

2020-02-14T10:48:11+00:00

This prepares the platform data to be easier to extend for more GPIOs.
Except of this there is no functional change.

Merge tag 'pinctrl-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

2020-01-29T17:51:36+00:00

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)"

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.
