Add alarm support for the Microchip RTC devices MCP794xx. Note that two
programmable alarms are provided by the chip but only one is used by the
driver.

In order to allow the creation of the sysfs attribute wakealarm, this
patch moves the device_set_wakeup_capable() call above the RTC device
registration.

RTC settings will be lost if power supply is cut off after hibernation
finished, but the current "restore" function does not restore RTC related
settings, this causes rtc_read_time failure and kernel panic:

for TYPE_S3C64XX
On exynos5250, exynos5420 and exynos5260 it was observed that, after 1
cycle of S2R, the rtc-tick occurs at a very fast rate as compared to the
rtc-tick occuring before S2R.
This patch fixes the above issue by correcting the wrong way of
save/restore of S3C2410_TICNT for TYPE_S3C64XX.

Add support for SMBus-only adapters (e.g. i2c-piix4). The driver has
implemented only support for I2C adapters which implement the
I2C_FUNC_SMBUS_I2C_BLOCK functionality before.
With this patch it is possible to load and use the RTC driver with I2C and
SMBUS adapters like the rtc-ds1307 does.
Tested on AMD G Series Platform (i2c-piix4 adapter driver).

The current MAX8907 driver has two issues related to weekday value
handling:
1)
The HW WEEKDAY register has range 0..6 rather than 1..7 as documented.
Note that I validated the actual HW range by observing the HW register
roll from 6->0 rather than 6->7->1 as would otherwise be expected.
This matches Linux's tm_wday range of 0..6.
When the CMOS RAM content is lost, the date returned from the device is
2007-01-01 00:00:00, which is a Monday. The WEEKDAY register reads 1 in
this case. This matches the numbering in Linux's tm_wday field.
Hence we should write Linux's tm_wday value to the register without
modifying it. Hence, remove the +1/-1 calculations for WEEKDAY/tm_wday.
2)
There's no need to make alarms match on the WEEKDAY register, since the
other fields together uniquely define the alarm date/time. Ignoring the
WEEKDAY value in the match isolates the driver from any incorrect value in
the current time copy of the WEEKDAY register.
Each change individually, or both together, solves an issue that I
observed; "hwclock -r" would time out waiting for its alarm to fire if the
CMOS RAM content had been lost, and hence the WEEKDAY register value
mismatched what the driver expected it to be. "hwclock -w" would solve
this by over-writing the HW default WEEKDAY register value with what the
driver expected.

Assign RTC device IDs based on device tree /aliases entries if present,
falling back to the existing numbering scheme if there is no /aliases
entry (which includes when the system isn't booted using DT), or there is
a numbering conflict.
This is useful in systems with multiple RTC devices, to ensure that the
best RTC device is selected as /dev/rtc0, which provides the overall
system time.
For example, Tegra has an on-SoC RTC that is not battery backed, typically
coupled with an off-SoC RTC that is battery backed. Only the latter is
useful for populating the system time, yet the former is useful e.g. for
wakeup timing, since the time is not lost when the system is sleeps.

only), rtc-cmos doesn't work well:
- The date is of by 32 years (2045 instead of 2013):
rtc_cmos rtc_cmos: setting system clock to 2045-12-02 10:56:17 UTC
(2395824977)
- The hwclock utility doesn't work:
hwclock: ioctl() to /dev/rtc to turn on update interrupts failed
unexpectedly, errno=5: Input/output error.
As rtc-generic works fine for the RTC part, and nvram works for the NVRAM
part, we'll continue on using that.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM driver updates from Olof Johansson:
"Updates of SoC-near drivers and other driver updates that makes more
sense to take through our tree.
The largest part of this is a conversion of device registration for
some renesas shmobile/sh devices over to use resources. This has
required coordination with the corresponding arch/sh changes, and
we've agreed to merge the arch/sh changes through our tree.
Added in this branch is support for Trusted Foundations secure
firmware, which is what is used on many of the commercial Nvidia Tegra
products that are in the market, including the Nvidia Shield. The
code is local to arch/arm at this time since it's uncertain whether it
will be shared with arm64 longer-term, if needed we will refactor
later.
A couple of new RTC drivers used on ARM boards, merged through our
tree on request by the RTC maintainer.

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.

41c7f7424259f ("rtc: Disable the alarm in the hardware (v2)") added the
functionality to disable the RTC wake alarm when shutting down the box.
However, there are at least two b0rked BIOSes we know about:
https://bugzilla.novell.com/show_bug.cgi?id=812592
https://bugzilla.novell.com/show_bug.cgi?id=805740
where, when wakeup alarm is enabled in the BIOS, the machine reboots
automatically right after shutdown, regardless of what wakeup time is
programmed.
Bisecting the issue lead to this patch so disable its functionality with
a DMI quirk only for those boxes.

Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.
On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC. This could be observed in various hangs,
e.g. in infinite loop during waiting for UDR field change.
On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.
