drivers/rtc/rtc-isl12057.c: fix masking of register values

2015-01-16T14:34:38+00:00

commit 5945b2880363ed7648e62aabba770ec57ff2a316 upstream.

When Intersil ISL12057 support was added by commit 70e123373c05 ("rtc: Add
support for Intersil ISL12057 I2C RTC chip"), two masks for time registers
values imported from the device were either wrong or omitted, leading to
additional bits from those registers to impact read values:

 - mask for hour register value when reading it in AM/PM mode. As
   AM/PM mode is not the usual mode used by the driver, this error
   would only have an impact on an externally configured RTC hour
   later read by the driver.
 - mask for month value. The lack of masking would provide an
   erroneous value if century bit is set.

This patch fixes those two masks.

rtc: isl12057: make of_device_id array const

2014-06-06T23:08:07+00:00

Make of_device_id array const, because all OF functions handle it as
const.

Pull ARM SoC driver changes from Arnd Bergmann:
 "These changes are mostly for ARM specific device drivers that either
  don't have an upstream maintainer, or that had the maintainer ask us
  to pick up the changes to avoid conflicts.

  A large chunk of this are clock drivers (bcm281xx, exynos, versatile,
  shmobile), aside from that, reset controllers for STi as well as a
  large rework of the Marvell Orion/EBU watchdog driver are notable"

rtc: Add support for Intersil ISL12057 I2C RTC chip

2013-12-22T17:33:16+00:00

Intersil ISL12057 is an I2C RTC chip also supporting two alarms. This
patch only adds support for basic RTC functionalities (i.e. getting
and setting time). Tests have been performed on NETGEAR ReadyNAS 102
w/ startup/shutdown scripts, hwclock, ntpdate and openntpd.
