Subject: [PATCH v11 1/4] dt-bindings: pwm: fix microchip corePWM's pwm-cells
Date: Fri, 7 Oct 2022 12:35:10 +0100	[thread overview]
Message-ID: <20221007113512.91501-2-conor.dooley@microchip.com> (raw)
In-Reply-To: <20221007113512.91501-1-conor.dooley@microchip.com>

corePWM is capable of inverted operation but the binding requires
\#pwm-cells of 2. Expand the binding to support setting the polarity.

Fixes: df77f7735786 ("dt-bindings: pwm: add microchip corepwm binding")
Acked-by: Rob Herring <robh@kernel.org>
Acked-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
