Subject: [PATCH v2 1/2] dt-bindings: hwmon: add binding documentation for adt7475
Date: Fri, 9 Nov 2018 11:56:06 +1300 [thread overview]
Message-ID: <20181108225607.7521-2-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20181108225607.7521-1-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.
Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz>
---
Changes in v2:
- use pwm-polarity attiribute to indicate normal or inverted polarity.

+ "adi,adt7475"
+ "adi,adt7476"
+ "adi,adt7490"
+
+- reg: I2C address

+optional properties:
+
+- pwm-polarity: This configures the polarity of the PWM. 0
+ (PWM_POLARITY_NORMAL) uses logic high for 100% duty cycle. 1
+ (PWM_POLARITY_INVERSED) uses logic low for 100% duty cycle.

+Example:

+hwmon@2e {
+ compatible = ;
+ reg = <0x2e>;
+ pwm-polarity = <1>;
+};
