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.)Signed-off-by: David Brownell

This patch adds support for the Simtek STK17TA8 timekeeping chip.
The STK17TA8 is quite similar to the DS1553, but differs in register layout

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"

RTC class suspend/resume support, re-initializing the system clock on resume
from the clock used to initialize it at boot time.- The reinit-on-resume is hooked to the existing RTC_HCTOSYS config
option, on the grounds that a clock good enough for init must also
be good enough for re-init.- Inlining a version of the code used by ARM, to save and restore the
delta between a selected RTC and the current system wall-clock time.- Removes calls to that ARM code from AT91, OMAP1, and S3C RTCs. This
means that systems using those RTCs across suspend/resume will likely
want to change their kernel configs to enable RTC_HCTOSYS.If HCTOSYS isn't using a second RTC (with battery?), this changes the
system's initial date from Jan 1970 to the epoch this hardware uses:
1998 for AT91, 2000 for OMAP1 (assuming no split power mode), etc.This goes on top of the patch series removing "struct class_device" usage
from the RTC framework. That's all needed for class suspend()/resume().Signed-off-by: David Brownell

This simplifies the RTC procfs support by removing the class_interface that
hooks it into the rtc core. If it's configured, then sysfs support is now
part of the RTC core, and is never a separate module.It also removes the class_interface hook, now that its last remaining user is
gone. (That API is usable only with a "struct class_device".)It's another step towards being able to remove "struct class_device".

Also, since this driver also contains Acorn RiscPC specific code

This is an "RTC framework" driver for the "CMOS" RTCs which are standard on
PCs and some other platforms. That's MC146818 compatible silicon.
Advantages of this vs. drivers/char/rtc.c (use one _or_ the other, only
one will be able to claim the RTC irq) include:- This leverages both the new RTC framework and the driver model; both
PNPACPI and platform device modes are supported. (A separate patch
creates a platform device on PCs where PNPACPI isn't configured.)- It supports common extensions like longer alarms. (A separate patch
exports that information from ACPI through platform_data.)- Likewise, system wakeup events use "real driver model support", with
policy control via sysfs "wakeup" attributes and and using normal rtc
ioctls to manage wakeup. (Patch in the works. The ACPI hooks are
known; /proc/acpi/alarm can vanish. Making it work with EFI will
be a minor challenge to someone with e.g. a MiniMac.)It's not yet been tested on non-x86 systems, without ACPI, or with HPET.
And the RTC framework will surely have teething pains on "mainstream"
PC-based systems (though must embedded Linux systems use it heavily), not
limited to sorting out the "/dev/rtc0" issue (udev easily tweaked). Also,
the ALSA rtctimer code doesn't use the new RTC API.Otherwise, this should be a no-known-regressions replacement for the old
drivers/char/rtc.c driver, and should help the non-embedded distros (and
the new timekeeping code) start to switch to the framework.Note also that any systems using "rtc-m48t86" are candidates to switch over
to this more functional driver; the platform data is different, and the way
bytes are read is different, but otherwise those chips should be compatible.[akpm@osdl.org: sparc32 fix]

This creates a new RTC-framework driver for the RTC/calendar module found
