[PATCH 0/2] TQMa7x / MBa7x DT improvements

[Markus Niebel]

This series brings two improvements: supporting the i.MX7 ADC paired
with HWMON support and using a more specific compatible for the
mainboard temperature sensor.

Markus Niebel (2):
  arm: dts: imx7-mba7: add iio-hwmon support
  arm: dts: imx7-mba7: improve compatible for LM75 temp sensor

[PATCH 1/2] arm: dts: imx7-mba7: add iio-hwmon support

[Markus Niebel]

Enable IIO hwmon support for ADC1 and ADC2. All channels are
available on X23 (ADC2) and X24 (ADC1) of MBa7x.

[PATCH 2/2] arm: dts: imx7-mba7: improve compatible for LM75 temp sensor

[Markus Niebel]

Use national,lm75a to specify exact variant used. This should cause
no functional changes.

We use prefix "ARM: dts: ..." for i.MX arm DTS changes.  Fix it up and
applied both, thanks!
