rtc: sirfsoc: switch to rtc_time64_to_tm/rtc_tm_to_time64

2020-03-16T10:12:09+00:00

Call the 64bit versions of rtc_tm time conversion to avoid the y2106 issue.

rtc: sirfsoc: set range

2020-03-16T10:12:09+00:00

This RTC is a 32bit counter running at 16Hz. This overflows every eight
years and a half. However, the driver uses the SW_VALUE register to store
the overflow, extending the counter to 64bit as long as the update happens
before the overflow.

rtc: sirfsoc: convert to devm_rtc_allocate_device

2020-03-16T10:12:08+00:00

This allows further improvement of the driver. Also remove the unnecessary
error string as the core will already display error messages.

rtc: sirfsoc: remove .remove

2019-11-08T15:14:09+00:00

dpm_sysfs_remove() and device_pm_remove() are already called by
device_del() on device removal so there is no need to call
device_init_wakeup(dev, false) from the driver and it allows to remove the
.remove callback.

rtc: sirfsoc: Make sysrtc_regmap_config static

2019-04-11T21:18:27+00:00

Fix sparse warning:

drivers/rtc/rtc-sirfsoc.c:282:28: warning:
 symbol 'sysrtc_regmap_config' was not declared. Should it be static?

rtc: sirfsoc: remove useless sirfsoc_rtc_ioctl

2018-03-01T09:49:27+00:00

sirfsoc_rtc_ioctl() doesn't implement any actual ioctl, remove it.

rtc: sirfsoc: move to regmap APIs from platform-specific APIs

2015-09-05T11:19:06+00:00

The current codes use CSR platform specific API exported by machine
codes to read/write RTC registers. they are:
sirfsoc_rtc_iobrg_readl()
sirfsoc_rtc_iobrg_writel()

commit b1999477ed91 ("ARM: prima2: move to use REGMAP APIs for rtciobrg")
moves to regmap support, now we can move to use regmap APIs in RTC
driver.

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"
