The error handling in ls1x_rtc_probe used to release resources but since
it is using devm functions, it only returns a value. Make the code clearer
by returning directly instead of using goto.

Let the core handle offsetting and windowing the RTC range.
The RTC has a 40-bit counter counting at 1024 Hz. So its maximum value is
2^(40-10) - 1. Also, let the core handle the offset instead of coding it in
the callbacks. Keep the default epoch at the beginning of 2009 (this will
fail in 2043).

RTC driver should not be aware of the PWR registers offset and bits
position. Furthermore, we can imagine that DBP relative register and bit
mask could change depending on the SoC.
So this patch introduces 2 parameters, dbp_reg and dbp_mask, allowing to
get PWR_CR and PWR_CR_DBP from device tree. And it prepares next RTC
version, backup domain write protection is disabled only if needed.

The tps6586x use a 64-bit 'epoch_start' value, but then computes that
value using an 'mktime()', which has a smaller range and overflows
in 2106 at the latest. As both the hardware and the subsystem interface
support wider than 32-bit ranges for rtc times here, let's change all
the operations on 'seconds' to time64_t.

The loongson1 platform is 32-bit, so storing a time value in 32 bits
suffers from limited range. In this case it is likely to be correct
until 2106, but it's better to avoid the limitation and just use
the time64_t based mktime64() and rtc_time64_to_tm() interfaces.
The hardware uses a 32-bit year number, and time64_t can cover that
entire range.

This driver uses mktime() and rtc_time_to_tm() to convert between time
values. This works fine on 64-bit kernels over the whole supported
range, and the vr41xx chip is a 64-bit MIPS implementation, but it is
inconsistent because it doesn't do the same thing on 32-bit kernels that
overflow in 2106 or 2038.
Changing it to use mktime64/rtc_time64_to_tm() should have no visible
impact on vr41xx but gets us closer to removing the 32-bit interfaces.

Use ACPI for RTC Alarm only for Intel platforms
1. with Low Power S0 support
2. with HPET RTC emulation enabled
3. no earlier than 2015
Note that, during the test, it is found that this patch
1. works in 4.15-rc kernel
2. hangs the platform after suspend-to-idle for 2 or 3 times, in 4.15.0
3. works again in 4.16-rc3 kernel.
4. works in the latest 4.15.12 stable kernel.
Thus although this patch breaks 4.15.0 kernel for some unknown reason,
still, it is safe for both upstream and backport.

Previously, the RTC alarm is acknowledged either by the cmos rtc irq
handler, or by the hpet rtc irq handler.
When using ACPI RTC Fixed event as the RTC alarm, the RTC alarm is
acknowledged by the ACPI RTC event handler, as addressed in the previous
patch.
But, when resume from suspend-to-ram (ACPI S3), the ACPI SCI is cleared
right after resume, thus the ACPI RTC event handler is not invoked at all,
results in the RTC Alarm unacknowledged.
Handle this by comparing the current time and the RTC Alarm time in the
rtc_cmos driver .resume() callback
1. Assume the wakeup event has already been fired if the RTC Alarm time
is earlier than/equal to the current time, and ACK the RTC Alarm.
2. Assume the wakeup event has not been fired if the RTC Alarm time
is later than current time, and re-arm it if needed.

It's found that the HPET timer prevents the platform from entering
Low Power S0 on some new Intel platforms.
This means that
1. users can still use RTC wake Alarm for suspend-to-idle, but the system
never enters Low Power S0, which is a waste of power.
or
2. if users want to put the system into Low Power S0, they can not use
RTC as the wakeup source.
To fix this, we need to stop using the HPET timer for wake alarm.
But disabling CONFIG_HPET_EMULATE_RTC is not an option because HPET
emulates PIT at the same time, and this is needed on some of these
platforms.
Thus, introduce a new mode (use_acpi_alarm) to the rtc_cmos driver,
so that, even with CONFIG_HPET_EMULATE_RTC enabled, it's still possible to
use ACPI SCI for RTC Alarm, including UIE/AIE/wkalrm, instead of HPET.
Only necessary changes are made for the new "use_acpi_alarm" mode, including
1. drop all the calls to HPET emulation code, including the HPET irq
handler for rtc interrupt.
2. enabling/disabling ACPI RTC Fixed event upon RTC UIE/AIE request.
3. acknowledge the RTC Alarm in ACPI RTC Fixed event handler.
There is no functional change made in this patch if the new mode is not
enabled.
Note: this "use_acpi_alarm" mode is made based on the assumption that
ACPI RTC Fixed event is reliable both at runtime and during system wakeup.
And this has been verified on a couple of platforms I have, including
a MS Surface Pro 4 (SKL), a Lenovo Yoga 900 (SKL), and a HP 9360 (KBL).

Pull SCSI fixes from James Bottomley:
"This is a set of minor (and safe changes) that didn't make the initial

The status handling code is actually a running regression from the
previous merge window which had an incomplete fix (now reverted) and
most of the remaining bug fixes are for problems older than the
current merge window"
[ Side note: this merge also takes the base kernel git repository to 6+
million objects for the first time. Technically we hit it a couple of
merges ago already if you count all the tag objects, but now it
reaches 6M+ objects reachable from HEAD.
I was joking around that that's when I should switch to 5.0, because
3.0 happened at the 2M mark, and 4.0 happened at 4M objects. But
probably not, even if numerology is about as good a reason as any.

"The large diff this time around is from the addition of a new clk
driver for the TI Davinci family of SoCs. So far those clks have been
supported with a custom implementation of the clk API in the arch port
instead of in the CCF. With this driver merged we're one step closer
to having a single clk API implementation.
The other large diff is from the Amlogic clk driver that underwent
some major surgery to use regmap. Beyond that, the biggest hitter is
Samsung which needed some reworks to properly handle clk provider
power domains and a bunch of PLL rate updates.
The core framework was fairly quiet this round, just getting some
cleanups and small fixes for some of the more esoteric features. And
the usual set of driver non-critical fixes, cleanups, and minor
additions are here as well.
Core:
- Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
- debugfs ops macroized to shave some lines of boilerplate code
- Always calculate the phase instead of caching it in clk_get_phase()

Pull block fixes from Jens Axboe:
"Followup fixes for this merge window. This contains:
- Series from Ming, fixing corner cases in our CPU <-> queue mapping.
This triggered repeated warnings on especially s390, but I also hit
it in cpu hot plug/unplug testing while doing IO on NVMe on x86-64.
- Another fix from Ming, ensuring that we always order budget and
driver tag identically, avoiding a deadlock on QD=1 devices.
- Loop locking regression fix from this merge window, from Omar.
- Another loop locking fix, this time missing an unlock, from Tetsuo
Handa.
- Fix for racing IO submission with device removal from Bart.
- sr reference fix from me, fixing a case where disk change or
getevents can race with device removal.
- Set of nvme fixes by way of Keith, from various contributors"
