pinctrl: armada-37xx: Add gpio support

2017-04-24T11:47:29Z

GPIO management is pretty simple and is part of the same IP than the pin controller for the Armada 37xx SoCs. This patch adds the GPIO support to the pinctrl-armada-37xx.c file, it also allows sharing common functions between the gpiolib and the pinctrl drivers.

pinctrl: armada-37xx: Add pin controller support for Armada 37xx

2017-04-24T09:31:36Z

The Armada 37xx SoC come with 2 pin controllers: one on the south bridge (managing 28 pins) and one on the north bridge (managing 36 pins). At the hardware level the controller configure the pins by group and not pin by pin. This constraint is reflected in the design of the driver: only the group related functions are implemented.

pinctrl: mvebu: make bool drivers explicitly non-modular

2017-02-13T13:25:49Z

None of the Kconfigs for any of these drivers are tristate, meaning that they currently are not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the drivers there is no doubt they are builtin-only. All drivers get the exact same change, so they are handled in batch. Changes are (1) use builtin_platform_driver, (2) dont use module.h (3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE, and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags. For the dove driver we explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We deleted the MODULE_LICENSE etc. tags since all that information is already contained at the top of the file in the comments.

pinctrl: mvebu: remove unused variable

2017-01-26T14:17:37Z

A cleanup caused a harmless warning: drivers/pinctrl/mvebu/pinctrl-kirkwood.c: In function 'kirkwood_pinctrl_probe': drivers/pinctrl/mvebu/pinctrl-kirkwood.c:460:19: error: unused variable 'res' [-Werror=unused-variable] The obvious fix is to remove the declaration of the now unused variable.

pinctrl: mvebu: add simple regmap based pinctrl implementation

2017-01-18T08:58:04Z

Add a simple regmap based pinctrl implementation for mvebu, for syscon based regmap drivers. Signed-off-by: Russell King Signed-off-by: Linus Walleij

pinctrl: mvebu: switch drivers to generic simple mmio

2017-01-18T08:56:35Z

Move the mvebu pinctrl drivers over to the generic simple mmio implementation, saving a substantial number of lines of code in the process. Signed-off-by: Russell King Signed-off-by: Linus Walleij

pinctrl: mvebu: provide generic simple mmio-based implementation

2017-01-18T08:55:27Z

Provide a generic simple mmio-based probe function and methods, which pinctrl drivers can use to initialise the mvebu pinctrl subsystem. Most mvebu pinctrl drivers can use this. Signed-off-by: Russell King Signed-off-by: Linus Walleij

pinctrl: mvebu: provide per-control private data

2017-01-18T08:54:24Z

Provide per-control private data into each mvebu pinctrl method, which will allow us to provide some completely generic helpers without the global variable and per-instance function definitions that would be required when we have multiple pin controllers on a SoC.
