Subject: [PATCH v5 1/4] dt-bindings: pwm: fix microchip corePWM's pwm-cells
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")
Signed-off-by: Conor Dooley <conor.dooley@...rochip.com>
