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.

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.

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

CONFIG_HOTPLUG is going away as an option so __devexit is no

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO changes from Linus Walleij:
- New driver for AMD-8111 southbridge GPIOs
- New driver for Wolfson Micro Arizona devices
- Propagate device tree parse errors
- Probe deferral finalizations - all expected calls to GPIO will now
hopefully request deferral where apropriate
- Misc updates to TCA6424, WM8994, LPC32xx, PCF857x, Samsung MXC, OMAP
and PCA953X drivers.
Fix up gpio_idx conflicts in drivers/gpio/gpio-mxc.c
* tag 'gpio-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
gpio: of_get_named_gpio_flags() return -EPROBE_DEFER if GPIO not yet available
gpiolib: Defer failed gpio requests by default
MAINTAINERS: add entry OMAP GPIO driver
gpio/pca953x: increase variables size to support 24 bit of data
GPIO: PCA953X: Increase size of invert variable to support 24 bit
gpio/omap: move bank->dbck initialization to omap_gpio_mod_init()
gpio/mxc: use the edge_sel feature if available
gpio: propagate of_parse_phandle_with_args errors
gpio: samsung: add flags specifier to device-tree binding
gpiolib: Add support for Wolfson Microelectronics Arizona class devices
gpio: gpio-lpc32xx: Add gpio_to_irq mapping
gpio: pcf857x: share 8/16 bit access functions
gpio: LPC32xx: Driver cleanup
MAINTAINERS: Add Wolfson gpiolib drivers to the Wolfson entry
gpiolib: wm8994: Convert to devm_kzalloc()
gpiolib: wm8994: Use irq_domain mappings for gpios
gpio: add a driver for GPIO pins found on AMD-8111 south bridge chips
gpio/tca6424: merge I2C transactions, remove cast
gpio/of: fix a typo of comment message

This has no practical impact at present since we don't support device tree
so any user must have set an irq_base but this will in future allow a
transition to device tree with minimal invasiveness.

Not paying attention to the value being set is a bad thing because it
means that we'll not set the hardware up to reflect what was requested.
Not setting the hardware up to reflect what was requested means that the
caller won't get the results they wanted.

Sort the gpio makefile and enforce the naming convention gpio-*.c for
gpio drivers.
v2: cleaned up filenames in Kconfig and comment blocks
v3: fixup use of BASIC_MMIO to GENERIC_GPIO for mxc
