drivers/char/rtc.c exposed a sysctl to change the maximum frequency at
which a non-root user could ask the RTC to generate interrupts (via the
RTC_IRQP_SET ioctl). This value is no longer available under the new RTC
subsystem, so add it to sysfs for each RTC device.Works for me on x86_64 (both reads and writes), using rtc-cmos.

Some cleanups for the rtc-cmos probe logic:
- Claim i/o ports with request_region() not request_resource(),
for better coexistence betwen platform and pnp bus glues.- Claim those ports earlier, to help work around procfs bugs
(it allows duplicate names, like /proc/driver/rtc).- Fix some glitches in cleanup code, notably a cut'n'paste-o
where the i/o port region might not get released during
cleanup after a probe fault.And some comment clarifications, including noting that this code
must work with PNPBIOS not just PNPACPI..[akpm@linux-foundation.org: coding-style fixes]

Fix readback of RTC alarms on platforms which return -1 in
non-hardware-supported RTC alarm fields.To fill in the missing (-1) values, we grab an RTC timestamp along with the
RTC alarm value, and use the timestamp fields to populate the missing alarm
fields.To counter field-wrap races (since the timestamp and alarm are not read
together atomically), we read the RTC timestamp both before and after
reading the RTC alarm value, and then check for wrapped fields --> if any
have wrapped, we know we have a possible inconsistency, so we loop and
reread the timestamp and alarm again.Wrapped fields in the RTC timestamps are an issue because rtc-cmos.c, for
example, also gets/uses an RTC timestamp internally while fetching the RTC
alarm. If our timestamp here wasn't the same (minutes and higher) as what
was used internally there, then we might end up populating the -1 fields
with inconsistent values.This fixes readbacks from /sys/class/rtc/rtc?/wakealarm, as well as other
code paths which call rtc_read_alarm().Signed-off-by: Mark Lord

RTC periodic IRQs are only defined to work for 2^N Hz values. This patch
moves that validity check into the infrastructure, so drivers don't need to
check it; and adds kerneldoc for the two interface functions related to

recently checked in!)Signed-off-by: David Brownell

All SH-4 parts have a 4-digit year, while the SH-3 parts typically
only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts
however opted to extend it to 4-digit and still look and act like
an SH-3 RTC in all other ways.This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these
corner-case CPU subtypes can set in their platform data and cleans
up some of the ifdef mess in the driver as a result.Reported-by: Markus Brunner

Currently the rtc driver, rtc-ds1742.c uses an unsigned long to store the
base mmio address of the NVRAM/RTC. This breaks on systems like PowerPC
440, which is a 32-bit core with 36-bit physical addresses: IO on the
system, including the RTC, is typically above the 4GB point, and cannot fit
into an unsigned long.This patch fixes the problem by replacing the unsigned long with a
resource_size_t. Tested on Ebony (PPC440) (with additional patches to
instantiate the ds1742 platform device appropriately).Signed-off-by: David Gibson

This avoids use of the kernel-internal "xtime" variable directly outside
of the actual time-related functions. Instead, use the helper functions
that we already have available to us.This doesn't actually change any behaviour, but this will allow us to
fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ
(because much of the realtime information is maintained as separate
offsets to 'xtime'), which has caused interfaces that use xtime directly
to get a time that is out of sync with the real-time clock by up to a
third of a second or so.Signed-off-by: John Stultz

Add Texas Instruments TWL92330/Menelaus Power Management chip driver. This
includes voltage regulators, Dual slot memory card tranceivers and
real-time clock(RTC).The support for RTC is integrated with this driver only; it is not separate
module. Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic"
(1/N second) IRQs. System wakeup alarms (from suspend-to-RAM) work too.The battery keeps the RTC active over power off, so once you set clock
(rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will
behave as expected.Cc: "Jean Delvare"
