* gpio: ts5500: Use devm_gpiochip_add_data() for gpio registrationLaxman Dewangan2016-02-231-6/+3
| | | | | | | Use devm_gpiochip_add_data() for GPIO registration and clean the error path. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com>
* gpio: ts5500: 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(). Acked-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gpio: change member .dev to .parentLinus Walleij2015-11-191-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Drivers: misc: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-3/+3
| | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* gpio: add TS-5500 DIO blocks supportVivien Didelot2012-12-101-0/+466
Technologic Systems TS-5500 provides digital I/O lines exposed through pin blocks. On this platform, there are three of them, named DIO1, DIO2 and LCD port, that may be used as a DIO block. The TS-5500 pin blocks are described in the product's wiki: http://wiki.embeddedarm.com/wiki/TS-5500#Digital_I.2FO This driver is not limited to the TS-5500 blocks. It can be extended to support similar boards pin blocks, such as on the TS-5600. This patch is the V2 of the previous https://lkml.org/lkml/2012/9/25/671 with corrections suggested by Linus Walleij.
