pinctrl: remove coh901 driver

2021-01-21T08:53:40+00:00

The ST-Ericsson U300 platform is getting removed, so this driver is no longer needed. Cc: Linus Walleij Signed-off-by: Arnd Bergmann Link: https://lore.kernel.org/r/20210120132045.2127659-5-arnd@kernel.org Signed-off-by: Linus Walleij

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: coh901: Pass irqchip when adding gpiochip

2019-09-30T21:10:01+00:00

We need to convert all old gpio irqchips to pass the irqchip setup along when adding the gpio_chip. For more info see drivers/gpio/TODO. For chained irqchips this is a pretty straight-forward conversion. Cc: Thierry Reding Signed-off-by: Linus Walleij Link: https://lore.kernel.org/r/20190913113530.5536-1-linus.walleij@linaro.org

treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 194

Based on 1 normalized pattern(s): license terms gnu general public license gpl version 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 161 file(s).

pinctrl: Include nothing else

2018-09-14T13:10:57+00:00

These drivers are GPIO drivers, and the do not need to use the legacy header in , go directly for instead. Replace any use of GPIOF_* with 0/1, these flags are for consumers, not drivers. Get rid of a few gpio_to_irq() users that was littering around the place, use local callbacks or avoid using it at all. Signed-off-by: Linus Walleij

gpio: Move irqdomain into struct gpio_irq_chip

2017-11-08T13:06:21+00:00

In order to consolidate the multiple ways to associate an IRQ chip with a GPIO chip, move more fields into the new struct gpio_irq_chip. Signed-off-by: Thierry Reding Acked-by: Grygorii Strashko Signed-off-by: Linus Walleij

pinctrl: coh901: constify gpio_chip structure

2017-08-14T13:00:59+00:00

This structure is only used to copy into another structure, so declare it as const. This issue was detected using Coccinelle and the following semantic patch: @r disable optional_qualifier@ identifier i; position p; @@ static struct gpio_chip i@p = { ... }; @ok@ identifier r.i; expression e; position p; @@ e = i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct gpio_chip e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct gpio_chip i = { ... }; In the following log you can see a significant difference in the code size and data segment, hence in the dec segment. This log is the output of the size command, before and after the code change: before: text data bss dec hex filename 12775 3696 64 16535 4097 drivers/pinctrl/pinctrl-coh901.o after: bss dec hex filename 12440 3640 64 16144 3f10 drivers/pinctrl/pinctrl-coh901.o Signed-off-by: Gustavo A.

pinctrl: coh901: fix initconst annotation

2016-02-15T19:40:52+00:00

Clang correctly points out that the section attribute for u300_gpio_confdata is in the wrong place: drivers/pinctrl/pinctrl-coh901.c:130:37: error: '__section__' attribute only applies to functions and global variables This moves it from the type name to the variable, so it actually gets discarded.

pinctrl: u300: use gpiochip data pointer

2016-01-05T13:14:54+00:00

This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of(). Signed-off-by: Linus Walleij

pinctrl: coh901: Be sure to clamp return value

2015-12-26T21:28:34+00:00

As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern. Signed-off-by: Linus Walleij
