+* Maxim max9611/max9612 current sense amplifier with 12-bits ADC interface
+
+Maxim max9611/max9612 is an high-side current sense amplifier with integrated
+12-bits ADC communicating over I2c bus.
+The device node for this driver shall be a child of a I2c controller.
+
+Required properties
+ - compatible: Should be "maxim,max961x"
I'ts not a good idea to use wildcards in compatible values.
Ask yourself: is this valid for any (future) value of "x"?
I suspect you already know the answer here :)
Hence please use "maxim,max9611" or "maxim,max9612".
The only difference between these two is a noninverting vs. inverting
input-to-output configuration. Does the driver need to care?
No, not right now, as the inverting/non-inverting output is on the
op-amp/comparator side, which is currently not supported by this driver.
Instead of using one or the other, should we use both, as long as it
does not makes any difference from driver perspective?
Thanks
