staging:iio:iio-trig-bfin-timer: Fix compile error

2013-09-28T10:46:18+00:00

This patch fixes the following compile errors for the iio-trig-bfin-timer
driver:
	drivers/staging/iio/trigger/iio-trig-bfin-timer.c: In function ‘iio_bfin_tmr_frequency_store’:
	drivers/staging/iio/trigger/iio-trig-bfin-timer.c:121: error: invalid storage class for function ‘iio_bfin_tmr_frequency_show’
	drivers/staging/iio/trigger/iio-trig-bfin-timer.c:118: warning: ISO C90 forbids mixed declarations and code
	drivers/staging/iio/trigger/iio-trig-bfin-timer.c:135: error: initializer element is not constant
	...

The issue was introduced in commit e5e26dd5 ("staging: iio: replace
strict_strto*() with kstrto*()") by leaving an excess opening bracket.

staging: iio: replace strict_strto() with kstrto()

2013-09-08T14:16:07+00:00

The usage of strict_strto*() is not preferred, because
strict_strto*() is obsolete. Thus, kstrto*() should be
used.

Previously, there were only strict_strtol(), strict_strtoul(),
strict_strtoull(), and strict_strtoll(). Thus, when converting
to the variables, only long, unsigned long, unsigned long long,
and long long can be used.

However, kstrto*() provides various functions handling all types
of variables. Therefore, the types of variables can be changed
properly.

iio:triggers:interrupt trigger - move out of staging.

2013-06-04T17:33:19+00:00

This is now a very simple trigger indeed but useful in many common cases.

staging:iio:triggers:interrupt trigger - one per platform device.

2013-06-04T17:32:53+00:00

Switching from one platform device registering a lot of triggers
to one for each trigger simplifies the code somewhat. It would be
relatively unusual to have more than a couple of such devices
registered so this change will not result in much additional overhead.

staging:iio:triggers: rename iio-trig-gpio to iio-trig-interrupt

2013-06-04T17:32:24+00:00

Also change all internal naming appropriately.
This trigger is no longer just for gpio provided interrupts so
change the naming to reflect this.  Also drop some now missleading
left over comments.

iio:trigger:sysfs Move out of staging.

2013-05-22T21:16:48+00:00

This simple driver is rather useful. No issues about its interface
have been raised for some time hence the proposal to move it out
of staging.

Pull removal of GENERIC_GPIO from Grant Likely:
 "GENERIC_GPIO now synonymous with GPIOLIB.  There are no longer any
  valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it
  is possible to do so which has been causing confusion and breakage.
  This branch does the work to completely eliminate GENERIC_GPIO."

GENERIC_GPIO is now equivalent to GPIOLIB and features that depended on
GENERIC_GPIO can now depend on GPIOLIB to allow removal of this option.

iio:trigger: Introduce iio_tigger_{set,get}_drvdata

2013-03-25T21:06:09+00:00

Introduce iio_tigger_{set,get}_drvdata which allows to attach driver specific
data to a trigger. The functions wrap access to the triggers private_data field
and all current users are updated to use iio_tigger_{set,get}_drvdata instead of
directly accessing the private_data field. This is the first step towards
removing the private_data field from the iio_trigger struct.

The following coccinelle script has been used to update the drivers:

@@
struct iio_trigger *trigger;
expression priv;
@@
-trigger->private_data = priv
+iio_trigger_set_drv_data(trigger, priv)

@@
struct iio_trigger *trigger;
@@
-trigger->private_data
+iio_trigger_get_drv_data(trigger)
