Subject[PATCH v4 0/3] ARM: berlin: ADC support
Date
Hi,

The Berlin ADC provides 8 channels, with one connected to a temperature
sensor. The temperature sensor has its own registers and both the ADC
and the temperature sensor need to be configured when using it.

This series is based on the two Berlin controllers rework series:
- https://lkml.org/lkml/2015/3/6/511
- https://lkml.org/lkml/2015/3/6/535

Antoine

Changes since v3:
- removed irq members from the berlin2_adc_priv struct
- stopped setting the data member to -1
- converted the temperature returned to milli Celsius

Changes since v2:
- took care of double free issues
- always enable the ADC in the device tree as there is no gated
clock
- moved the interrupt enable code before the channel reading
function
- cosmetic changes

Changes since v1:
- updated to use regmap_update_bits()
- fixed mixed berlin/berlin2 and some prefixes
- reworked channel definitions
- moved to IIO_CHAN_INFO_PROCESSED for the tsen
- fixed some typos
- cosmetic changes
