Subject: [PATCH v2 0/9] rtc: isl12022: cleanups and hwmon support

This series does a few cleanups of the isl12022 driver,

- removes use of deprecated function
- removes some redundant code
- switches to regmap API instead of private helpers

It also provides range_min, range_max values and finally hooks up the
temperatur sensor to hwmon.

Changes in v2:

- Use devm_hwmon_device_register_with_info() (Guenter), and use the
  opportunity to also expose an update_interval with the constant
  value 60000.

- Convert some dev_dbgs to use %ptR, remove a dev_info() (Alexandre)

- Add patch setting range_min, range_max (Alexandre)

Not changed in v2: For now, I've kept the low-battery
dev_warn(). Implementing support for the ioctls RTC_VL_READ/RTC_VL_CLR
is on my radar, but I will need some more time for reading up on and
deciding on the details of what the chip provides and how to map that
information to the various defined RTC_VL_* bits. I also need to
figure out a good way to reliably trigger a low-battery condition so I
can test the ioctl support. So I hope these patches can go in for now
and not be blocked on the series expanding even further.

Rasmus Villemoes (9):
  rtc: isl12022: stop using deprecated devm_rtc_device_register()
  rtc: isl12022: specify range_min and range_max
  rtc: isl12022: drop a dev_info()
  rtc: isl12022: simplify some expressions
  rtc: isl12022: use %ptR
  rtc: isl12022: use dev_set_drvdata() instead of i2c_set_clientdata()
  rtc: isl12022: drop redundant write to HR register
  rtc: isl12022: switch to using regmap API
  rtc: isl12022: add support for temperature sensor
