gpio: generic: add request function pointer

2014-05-23T12:31:51+00:00

gpiolib will require all gpio drivers to expicitly set the request
function pointer in the future. To encourage gpio driver developers
to adhere to this standard gpio-generic.c now sets this function
pointer.

gpio: generic: clamp retured value to [0,1]

2014-02-06T09:33:48+00:00

The generic GPIO would return 0 for low generic GPIO, and
something != 0 for high GPIO. Let's make this sane by clamping
the returned value to [0,1].

gpio: generic: Add label to platform data

2014-02-06T09:33:47+00:00

When registering more than one platform device, it is
useful to set the gpio chip label in the platform data.

GPIO: gpio-generic: remove kfree() from bgpio_remove call

2013-04-11T17:33:54+00:00

Memory for basic-mmio-gpio driver is allocated by the driver
using it, whether it's the generic GPIO driver itself or another
driver. In either case, the owner shall allocate and free the
struct bgpio_chip it is using, preferably using a managed
resource.

gpio: gpio-generic: Add 16 and 32 bit big endian byte order support

2013-04-10T21:41:16+00:00

There is no general support for 64-bit big endian accesses, so that is
left unsupported.

gpio: remove use of __devexit

CONFIG_HOTPLUG is going away as an option so __devexit is no

gpio/generic: initialize basic_mmio_gpio shadow variables properly

2012-05-19T18:17:35+00:00

It fixes the issue in gpio-generic that commit fb14921 (gpio/mxc: add
missing initialization of basic_mmio_gpio shadow variables) manged to
fix in gpio-mxc driver, so that other platform specific drivers do not
suffer from the same problem over and over again.

Changes since v1:
* Turn the last parameter of bgpio_init() "bool big_endian" into
  "unsigned long flags" and give those really quirky hardwares a
  chance to tell that reg_set and reg_dir are unreadable.
