drivers/rtc/rtc-stmp3xxx.c: remove redundant of_match_ptr

2013-11-13T03:09:30+00:00

The data structure of_match_ptr() protects is always compiled in.
Hence of_match_ptr() is not needed.

drivers/rtc/rtc-stmp3xxx.c: provide timeout for potentially endless loop polling a HW bit

2013-08-14T00:57:48+00:00

It's always a bad idea to poll on HW bits without a timeout.

The i.MX28 RTC can be easily brought into a state in which the RTC is
not running (until after a power-on-reset) and thus the status bits
which are polled in the driver won't ever change.

This patch prevents the kernel from getting stuck in this case.

drivers/rtc/rtc-stmp3xxx.c: check the return value from stmp_reset_block()

2013-07-09T17:33:25+00:00

stmp_reset_block() may fail, so let's check its return value and
propagate it in the case of error.

rtc: rtc-stmp3xxx: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:52+00:00

The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
= NULL when no driver is bound").  Thus, it is not needed to manually
clear the device driver data to NULL.

2013-05-02T16:03:55+00:00

Pull ARM SoC cleanup from Olof Johansson:
 "Here is a collection of cleanup patches.  Among the pieces that stand
  out are:

   - The deletion of h720x platforms
   - Split of at91 non-dt platforms to their own Kconfig file to keep
     them separate
   - General cleanups and refactoring of i.MX and MXS platforms
   - Some restructuring of clock tables for OMAP
   - Convertion of PMC driver for Tegra to dt-only
   - Some renames of sunxi -> sun4i (Allwinner A10)
   - ... plus a bunch of other stuff that I haven't mentioned"

rtc: rtc-stmp3xxx: convert stmp3xxx_rtcdrv to dev_pm_ops

2013-04-30T01:28:40+00:00

Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management.

rtc: stmp3xxx: use stmp_reset_block() instead

2013-04-01T08:30:05+00:00

The function stmp_reset_block() provides the exactly same functionality
as mxs_reset_block().  So use stmp_reset_block() instead, so that
 inclusion can be removed.

rtc: stmp3xxx: add wdt-accessor function

2013-03-01T11:40:36+00:00

This RTC also includes a watchdog timer. Provide an accessor function
for setting the watchdog timeout value which will be picked up by a
watchdog driver. Also register the platform_device for the watchdog here
to get the boot-time dependencies right.

drivers/rtc: use of_match_ptr() macro

2013-02-22T01:22:27+00:00

This eliminates having an #ifdef returning NULL for the case when OF is
disabled.  Maintains consistency in cases where OF is always selected.
