Why is this split from original binding? This does not make much
sense... Add complete hardware description.


Ok Krzysztof, I will merg the "[PATCH 1/3] dt-bindings: hwmon: Add maxim max31790 driver bindings" commit and "[PATCH 3/3] dt-bindings: hwmon: max31790: Add pwmout-pin-as-tach-input property" commit.

+      An array of six integers responds to six PWM channels for
+      configuring the pwm to tach mode.
+      When set to 0, the associated PWMOUT produces a PWM waveform for
+      control of fan speed. When set to 1, PWMOUT becomes a TACH input

No vendor prefix, so generic property... but where is it defined?


Thank Krzysztof! It is not generic property, I'll add the vendor prefix.

I'll update the "pwmout-pin-as-tach-input" to "maxim,pwmout-pin-as-tach-input" at v2.


Best regards,
Krzysztof
