Pull regulator updates from Mark Brown:
 "This is a relatively busy release for the regulator API, as well as a
  good collection of new drivers we've got a little bit of core work and
  a bunch of cleanup throughout the subsystem:

   - Support for propagating undervoltage events to child regulators

   - Undo enables done on supplies when setting enabling regulators via
     constraints fails

   - Pull in some gpiolib changes adding support for shared GPIOs to the
     gpiolib core, using them to replace the open coded variant of this
     that we've had in the regulator API for a long time

   - Support for Fitipower FP9931 and JD9330, Mediatek MT6316, MT6363
     and MT6373, NXP PF1550 and Qualcomm PMH01XX and PMCX0102

  The PF1550 support was originally going to go via the MFD tree but
  Krzysztof's cleanup work overlapped with it so I pulled in Lee's
  signed tag with support for the device"

The driver is doing a 64-bit divide, rather than using the proper
helpers, causing link errors on i386 allyesconfig builds:

  x86_64-linux-ld: drivers/power/supply/intel_dc_ti_battery.o: in function `dc_ti_battery_get_voltage_and_current_now':
  intel_dc_ti_battery.c:(.text+0x5c): undefined reference to `__udivdi3'
  x86_64-linux-ld: intel_dc_ti_battery.c:(.text+0x96): undefined reference to `__udivdi3'

and while fixing that, fix the double rounding: keep the timing
difference in nanoseconds ('ktime'), and then just convert to usecs at
the end.

Not because the timing precision is likely to matter, but because doing
it right also makes the code simpler.

The charge control disabling does not work as expected and needs
more time to be figured out correctly. Drop this feature for now.

Add support for RT9756 smart cap divider charger.

The RT9759 is a high efficiency and high charge current charger. The
maximum charge current is up to 8A. It integrates a dual-phase charge
pump core with ADC monitoring.

Mirroring drivers/macintosh/apm_emu.c, this means that
  modprobe apm_power && modprobe $anotherdriver && modprobe -r apm_power
leaves $anotherdriver's apm_get_power_status instead of deleting it.

The build of intel_dc_ti_battery module on i386 (32-bit) fails with

ERROR: modpost: "__udivdi3" [drivers/power/supply/intel_dc_ti_battery.ko]

This is caused by 64-bit division of ktime values by NSEC_PER_USEC. Use
ktime_divns() helper which handles the division correctly on 32-bit
architectures.

Existing userspace (in particular, upower) disables charge control by
setting the start threshold to 0 and the stop threshold to 100.

Handle that by actually setting the enable bit to 0 when a start
threshold of 0 was requested.

The sysfs API documentation says that drivers "round written values to
the nearest supported value" for charge_control_end_threshold.

Let's do this for both thresholds, as userspace (e.g. upower) generally
does not expect these writes to fail at all.
