This adds support for the RTC provided by the Wolfson Microelectronics
WM8350.
This driver was originally written by Graeme Gregory and Liam Girdwood,
though it has been modified since then to update it to current mainline
coding standards and for API completeness.

This adds a driver for the RTC inside the TWL4030 multi-function device.
It's a fairly basic RTC, with a wake-capable alarm.
Note that many of the pre-release Overo boards now in circulation can't
effectively use this RTC, because of a wiring error that puts its TWL
chip into "secure" mode. (As in "secure yourself against tampering".)
This isn't an issue on other OMAP3 boards now supported in mainline,
such as Beagle and Labrador.

Add support for M41T65 Real Time Clock chip.
The main differences I see between the M41T65 and M41T80 are that:
1) The M41T65 watchdog timer has three bits controlling resolution
(versus two for the M41T80).
2) There is no register 0x13 for controlling square-wave output.

Ramtron FM3130 is a chip with two separate devices inside, RTC clock and
FRAM. This driver provides only RTC functionality.
This chip is met in lots of custom boards with AT91SAMXXXX CPU I work
with, is cheap and in no way better or worse than any other RTC on market.
While it is mostly met on much smaller devices, I think it is great to
have it supported in Linux.

Kconfig tweaks to help reduce RTC configuration bugs, by avoiding
legacy RTC drivers when the generic RTC framework is enabled:
- If rtc-cmos is selected, disable the legacy rtc driver;
- When using generic RTC on x86, enable rtc-cmos by default;
- In the old "chardev RTC" section of Kconfig, add a comment
warning people off these (seven) legacy RTC drivers when
the generic framework is in use.
People can still use the legacy drivers if they want (or need) to.
This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver.
Ideally it would be a full list of platforms where it works, not a partial
list of ones where it won't. Or better yet, it would depend on a
"HAVE_CMOS_RTC" flag defined by various platforms ... surely there's a
Kconfig style guideline lurking there.

AT91sam9 RTC support, primarily in the form of an RTT-as-RTC driver that was
extracted from 2.6.23-at91 patch and updated:
- Relies on now-merged platform updates, which associate the RTT
hardware address with each RTT and use the "at91_rtt" name.
- RTC framework related fixes and cleanups, notably:
* removed now-needless suspend/resume clock offset logic
* alarm read/write now respects the "enabled" flag
* suspend always disables update irqs
* shutdown (and startup) disables all irqs
- Misc cleanup:
* use dev_*() messaging
* add comments
* remove globals,
* ... etc
- Don't force use of RTT0 and GPBR0. Either resource may need
to be used for other purposes (like NO_HZ support).
- Update "AT91RM9200 RTC" Kconfig to allow it on SAM9RL chips
(it has both RTT and RTC).
Driver binding uses bus_find_device() to avoid needing any kind of "timer
library" code when there's more than one RTT module. (This timer can be used
as an RTC, to support NO_HZ operation, or potentially for other stuff. The
choice is a per-system policy.)

This adds a basic ds1302 RTC driver, which is basically a cleanup and move
of the in-tree SH SecureEdge5410 code (which is currently located in
arch/sh/board/snapgear/rtc.c) to drivers/rtc.
This aims to be a building block that the M32R and CRIS code can be worked
on top of, so we can get rid of drivers/char/ds1302.c and
arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is
needed for this.

The RTC "hctosys" mechanism expects that RTC clock will use UTC, not local
time (e.g. PST). Say so in Kconfig and in the kernel message.
(Strictly speaking, the RTC clock should be tracking the POSIX epoch. That's
not worth going into here. Goofing timezones means clocks are wrong by many
hours; the POSIX-v-UTC differences just cost seconds.)

Both shwdt and rtc-sh are only supported on SH-3 and SH-4 at
the moment, don't allow them to break the SH-2 and SH-5 (sh64)
builds.

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.
