[PATCH v3 0/2] hwmon: (ina2xx):Add Suppor for passing alert polarity from device tree to driver

[Amna Waseem]

The INA230 has alert polarity bit in Mask/Enable register which can be
configured to be active high or active low depending upon the requirements
of the hardware using this chip. The patches in this series adds the support
for passing alert polarity value from device tree to the driver. Alert polarity
property is added device tree bindings and the driver is modified to read
this property and set the Alert polarity (APOL) bit value in Mask/Enable register
of INA230.

Changes in v3:
- Convert the alert polarity property in dt bindings to be a flag
- Set alert polarity depending upon on the presence of flag in
  device tree. Otherwise, default value is set
- Make setting of alert polarity to be chip specific since only
  ina226,ina230 and ina231 supports alert polarity setting. 
- Link to v2: https://lore.kernel.org/r/20240529-apol-ina2xx-fix-v2-0-ee2d76142de2@xxxxxxxx

Changes in v2:
- Add vendor specific prefix to alert polarity property in binding.
- Minor improvement in description of alert polarity binding property
- Remove usage of mutex while setting alert polarity in Mask/Enable
  register
- Correct indentation
- Link to v1: https://lore.kernel.org/r/20240529-apol-ina2xx-fix-v1-0-77b4b382190f@xxxxxxxx
