Subject: [PATCH v2 0/2] hwmon: (ina2xx):Add Suppor for passing alert
 polarity from device tree to driver

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.
