dd35bdb076 rtc: isl1208: add support for isl1219 with tamper detection
We add support for the ISL1219 chip that got an integrated tamper
detection function. This patch implements the feature by adding
an additional timestamp0 file to sysfs device path.
This file contains seconds since epoch, if an event occurred,
or is empty, if none occurred.

a0a1a1ba30 rtc: sysfs: facilitate attribute add to rtc device
This patches addresses following problem:
rtc_allocate_device
devm_device_add_group  <-- kernel oops / null pointer, because
			sysfs entry does not yet exist
rtc_register_device
rc = devm_device_add_group
if (rc)
	return rc;     <-- forbidden to return error code
			after device register

This patch adds rtc_add_group(s) functions.
The functions store the sum of attribute groups as device resource.

ec9cf1b7a6 rtc: pcf85063: preserve control register value between stop and start
Fix a bug that caused the Control_1 register to get zeroed whenever the
RTC time is set. The problem occurred between stopping and starting the
RTC clock, wherein the return value of a successful I2C write function
would get written to the register.

Also update variables of the start and stop functions to be more
consistent with the rest of the driver.

5089ea15ba rtc: use ktime_get_real_ts64() instead of getnstimeofday64()
getnstimeofday64() is just a wrapper around the ktime accessor, so
we should use that directly.

I considered using ktime_get_boottime_ts64() (to avoid leap second
problems) or ktime_get_real_seconds() (to simplify the calculation,
but in the end concluded that the existing interface is probably
the most appropriate in this case.

1a990fefb6 rtc: armada38x: reset after rtc power loss
When the RTC block looses power it needs a reset sequence to make it
usable again. Otherwise, writes to the time register have no effect.

This reset sequence combines information from the mvebu_rtc driver in
the Marvell provided U-Boot, and the SolidRun provided U-Boot repo.

Tested on the Armada 388 based SolidRun Clearfog Base.

cd7f3a249d rtc: snvs: Add timeouts to avoid kernel lockups
In order to read correctly from asynchronously updated RTC registers,
it's necessary to read repeatedly until their values do not change from
read to read.  It's also necessary to wait for three RTC clock ticks for
certain operations.  There are no timeouts in this code and these
operations could possibly loop forever.

To avoid kernel hangs, put in timeouts.

The iMX7d can be configured to stop the SRTC on a tamper event, which
will lockup the kernel inside this driver as described above.

These hangs can happen when running under qemu, which doesn't emulate
the SNVS RTC, though currently the driver will refuse to load on qemu
due to a timeout in the driver probe method.

It could also happen if the SRTC block where somehow placed into reset
or the slow speed clock that drives the SRTC counter (but not the CPU)
were to stop.

The symptoms on a two core iMX7d are a work queue hang on
rtc_timer_do_work(), which eventually blocks a systemd fsnotify
operation that triggers a work queue flush, causing systemd to hang and
thus causing all services that should be started by systemd, like a
console getty, to fail to start or stop.

Also optimize the wait code to wait less.  It only needs to wait for the
clock to advance three ticks, not to see it change three times.

 "This contains some small RISC-V updates I'd like to target for 4.18.

  They are all fairly small this time. Here's a short summary, there's
  more info in the commits/merges:

   - a fix to __clear_user to respect the passed arguments.

   - enough support for the perf subsystem to work with RISC-V's ISA
     defined performance counters.

   - support for sparse and cleanups suggested by it.

   - support for R_RISCV_32 (a relocation, not the 32-bit ISA).

   - some MAINTAINERS cleanups.

   - the addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's
     always present.

  I've given these a simple build+boot test"
