* drivers: gpio: tb10x: use devm_platform_ioremap_resource()Enrico Weigelt, metux IT consult2019-04-041-3/+1
| | | | | | | | Use the new helper that wraps the calls to platform_get_resource() and devm_ioremap_resource() together. Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gpio: tb10x: Use GENERIC_GPIOLinus Walleij2018-08-291-66/+30
| | | | | | | | | | Instead of open coding logic for reading and writing GPIO lines, use the generic GPIO library. Also switch to using the spinlock from the generic GPIO to protect the registers.

* gpio: tb10x: Create local helper variablesLinus Walleij2018-08-291-13/+14
| | | | | | | | | | | | Create a local struct device *dev helper variable to make the code easier to read. Most GPIO drivers use "np" (node pointer) rather than "dn" (device node) to point to the device tree node. Let's follow this convention.

* gpio: Convert to using %pOF instead of full_nameRob Herring2017-08-141-1/+2
| | | | | | | | | | | | | | | | | | | | Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

* gpio: tb10x: use gpiochip data pointerLinus Walleij2016-01-051-11/+6
| | | | | | | | | 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(). Cc: Christian Ruppert <christian.ruppert@abilis.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gpio: change member .dev to .parentLinus Walleij2015-11-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The name .dev in a struct is normally reserved for a struct device that is let us say a superclass to the thing described by the struct. struct gpio_chip stands out by confusingly using a struct device *dev to point to the parent device (such as a platform_device) that represents the hardware. As we want to give gpio_chip:s real devices, this is not working. We need to rename this member to parent. This was done by two coccinelle scripts, I guess it is possible to combine them into one, but I don't know such stuff. They look like this: @@ struct gpio_chip *var; @@ -var->dev +var->parent and: @@ struct gpio_chip var; @@ -var.dev +var.parent and: @@ struct bgpio_chip *var; @@ -var->gc.dev +var->gc.parent Plus a few instances of bgpio that I couldn't figure out how to teach Coccinelle to rewrite. This patch hits all over the place, but I *strongly* prefer this solution to any piecemal approaches that just exercise patch mechanics all over the place. It mainly hits drivers/gpio and drivers/pinctrl which is my own backyard anyway.

* gpio: gpio-tb10x: remove incorrect __exit markupDmitry Torokhov2015-03-271-1/+1
| | | | | | | | | | | Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes.

* | gpio/pinctrl: make gpio_chip members typed booleanLinus Walleij2013-12-041-1/+1
|/ | | | | | | | | | | This switches the two members of struct gpio_chip that were defined as unsigned foo:1 to bool, because that is indeed what they are. Switch all users in the gpio and pinctrl subsystems to assign these values with true/false instead of 0/1. The users outside these subsystems will survive since true/false is 1/0, atleast we set some kind of more strict typing example. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
