[PATCH v2 0/7] ARM: dts: meson: chip temperature (hwmon) support

[Martin Blumenstingl <martin.blumenstingl@googlemail.com>]

Now that the Meson SAR ADC driver can get the chip temperature on
Meson8, Meson8b and Meson8m2 (see [0]) we can add the missing bits to
the .dts{,i} and enable iio-hwmon for all boards where this could be
tested successfully.

This was successfully tested on multiple boards:
- Meson8b Odroid-C1 (me)
- Meson8b EC-100 (me)
- Meson8m2 M8S (not upstream yet, me)
- Meson8m2 MXIII-Plus (an earlier version of this series, Oleg Ivanov)

compile-time dependencies:
- none
runtime dependencies:
- my other series "meson-saradc: temperature sensor support for
  Meson8b/Meson8m2" from [0]
- multi_v7_defconfig already enables CONFIG_SENSORS_IIO_HWMON, so
  there's no patch which selects that.


Changes since v1 at [1]:
- added patch 1 at the start of the series because patches #3 and #4
  require the HHI memory region to be a syscon, which is what patch
  #1 provides. Thanks for spotting this Kevin!

Martin Blumenstingl (7):
  ARM: dts: meson: switch the clock controller to the HHI register area
  ARM: dts: meson8m2: use the Meson8m2 specific SAR ADC compatible
  ARM: dts: meson8: add the temperature calibration data for the SAR ADC
  ARM: dts: meson8b: add the temperature calibration data for the SAR
    ADC
  ARM: dts: meson8b: ec100: add iio-hwmon for the chip temperature
  ARM: dts: meson8b: odroidc1: add iio-hwmon for the chip temperature
  ARM: dts: meson8m2: mxiii-plus: add iio-hwmon for the chip temperature
