pinctrl: meson: Drop pinctrl_unregister for devm_ registered device

2016-09-07T06:34:48+00:00

commit 5b236d0fde21d88351420ef0b9a6cb7aeeea0c54 upstream. It's not necessary to unregister pin controller device registered with devm_pinctrl_register() and using pinctrl_unregister() leads to a double free. This is detected by Coccinelle semantic patch.

pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map

2016-04-01T13:06:36+00:00

Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since it does not depend on device tree despite the current name. This will enforce a consistent naming in pinctr-utils.c and will make it clear it can be called from outside device tree (e.g. from ACPI handling code).

pinctrl: amlogic: Make driver independent from two-domain configuration

2016-03-09T06:00:28+00:00

In the Amlogic Meson8 / Meson8b platforms we have two different buses: cbus and aobus, corresponding to 2 different power domains (regular and always-on). On each bus a different set of registers is mapped to manage muxes, GPIOs and in general to control a clear subset of the pins. Considering this architecture, having two different pinctrl devices, one for each bus / power domain, makes much more sense than just having one single device. Right now we have one single pin controller driver that uses two different domains (represented by 'gpio' and 'gpio-ao' sub-nodes in the DTS) to manage the set of registers on the two buses. This dual-domain configuration is hardcoded into the driver that strictly requires one domain for each bus in the same pin controller device. With this patch we refactor the driver to allow splitting the driver in two parts. This change is needed to have a proper description of the HW in the device-tree where we want to introduce aobus and cbus. Signed-off-by: Carlo Caione Signed-off-by: Linus Walleij

pinctrl: meson: make explicitly non-modular

2016-03-09T03:23:05+00:00

The Kconfig currently controlling compilation of this code is: drivers/pinctrl/Kconfig:config PINCTRL_MESON drivers/pinctrl/Kconfig: bool ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We don't replace module.h with init.h since the file already has that. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

pinctrl: meson: use gpiochip data pointer

2016-01-05T13:14:50+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(). Cc: Beniamino Galvani Cc: Carlo Caione Cc: Antoine Tenart Signed-off-by: Linus Walleij

gpio: change member .dev to .parent

2015-11-19T08:24:35+00:00

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.
