This patch serie adds support for thermal monitoring block on Qualcomm's
PMIC5 chips. PM8150{,b,l} and sm8250-mtp board device trees are extended
to support thermal zones provided by this thermal monitoring block.
Unlike the rest of PMIC thermal senses, these thermal zones describe
particular thermistors, which differ between from board to board.

Changes since v8:
 - Simplified qcom_vadc_map_voltage_temp() code by removing ascending
   tables support
 - Simplified qcom-vadc-common volt/temp mapping code
 - Implement suggestions by Matthias Kaehlcke: message formatting,
   rewrite comments, remove unused variable initialization.

Changes since v7:
 - Move qcom-vadc-common.h header to include/linux/iio/adc/ dir.
 - Use explicit sizeof(var) instead of hand-coding 1 when accessing
   adc-tm registers.
 - Remove buffer read from adc_tm5_init().
 - Remove extra on-stack var from adc_tm5_get_temp().
 - Minor formatting changes as suggested Daniel.

Changes since v6:
 - Added include <linux/bitfield.h> as noted by Jishnu Prakash.

Changes since v5:
 - Reworked DT bindings:
   * Removed qcom,adc-channel, instead it is parsed from io-channels
   * Renamed qcom,hw-settle-time to include -us suffix
 - Re-added monitor enabling which got lost during refactored. Noted by
   Jishnu Prakash.
 - Use threaded IRQ handler as susggested by Jishnu.

Changes since v4:
 - Added kernel-doc comments to ADC-TM structures
 - Used several sizeof(buf) instead of hand-conding register size

Changes since v3:
 - Fix DT description to spell "thermal monitoring" instead of just TM
 - Fix warnings in DT example
 - Add EXPORT_SYMBOL_GPL(of_iio_channel_get_by_name)
 - Fixed whitespace chanes in qcom-vadc-common.c
 - Removed error message if IIO chanel get returns -EPROBE_DEFER

Changes since v2:
 - IIO: export of_iio_channel_get_by_name() function
 - dt-bindings: move individual io-channels to each thermal monitoring
   channel rather than listing them all in device node
 - added fallback defaults to of_device_get_match_data calls in
   qcom-spmi-adc5 and qcom-spmi-adc-tm5 drivers
 - minor typo fixes

Changes since v1:
 - Introduce fixp_linear_interpolate() by Craig Tatlor
 - Lots of syntax/whitespace changes
 - Cleaned up register definitions per Jonathan's suggestion
 - Implemented most of the suggestions from Bjorn's and Jonathan's
   review

Shall I take patch 1/15 and 12/15 ?

12/15 will not compile without several previous patches, so it might
be better to take all of them through the single tree.

Ok, I will take some time to review the driver and ack it, so it can be
merged through the iio tree.

Daniel, I'm sorry. Is there any update on this patchset review?
