Subject: [PATCH 1/2] dt-bindings: hwmon: add binding documentation for adt7475
Date: Wed, 7 Nov 2018 17:00:09 +1300 [thread overview]
Message-ID: <20181107040010.27436-2-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20181107040010.27436-1-chris.packham@alliedtelesis.co.nz>
With the addition of the invert-pwm property the adt7475 needs its own
binding documentation rather being captured under trivial-devices.txt.

+ "adi,adt7475"
+ "adi,adt7476"

+- invert-pwm: This configures the PWM to use logic low for 100% duty cycle.
