rtc: ab8500: remove useless check

2018-09-28T12:36:49+00:00

rtc_time_to_tm always rturns a valid tm, there is no need to validate it.

rtc: ab8500: let the core handle range

2018-09-28T12:36:47+00:00

Let the core handle offsetting and windowing the RTC range.
The RTC has a 24 bit counter for minutes plus a seconds counter.
Keep the epoch at the beginning of 2000.

rtc: ab8500: Drop AB8540 support

2018-03-27T08:45:05+00:00

The AB8540 was an evolved version of the AB8500, but it was never
mass produced or put into products, only reference designs exist.
The upstream support was never completed and it is unlikely that
this will happen so drop the support for now to simplify
maintenance of the AB8500.

rtc: stop validating rtc_time after rtc_time_to_tm

2018-03-01T09:49:41+00:00

rtc_time_to_tm never generates an invalid tm. It is not necessary to
validate it.

rtc: ab8500: remove misuse of IRQF_NO_SUSPEND flag

2015-11-08T13:12:25+00:00

The IRQF_NO_SUSPEND flag is used to identify the interrupts that should
be left enabled so as to allow them to work as expected during the
suspend-resume cycle, but doesn't guarantee that it will wake the system
from a suspended state, enable_irq_wake is recommended to be used for
the wakeup.

This patch removes the use of IRQF_NO_SUSPEND flags and uses newly
introduce PM wakeup APIs dev_pm_{set,clear}_wake_irq.

rtc: ab8500: Add a sentinel to ab85xx_rtc_ids[]

rtc: Fix module autoload for rtc-{ab8500,max8997,s5m} drivers

2015-09-05T17:37:21+00:00

These platform drivers have a platform device ID table but the module
alias information is not created so module autoloading will not work.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"
