Subject: [RFC PATCH 1/3] dt-bindings: gpio-rcar: Add optional use-alternative-interrupt property
Date: Wed, 22 Apr 2020 12:10:24 +0200 [thread overview]
Message-ID: <20200422101026.9220-2-erosca@de.adit-jv.com> (raw)
In-Reply-To: <20200422101026.9220-1-erosca@de.adit-jv.com>
From: Torii Kenichi <torii.ken1@jp.fujitsu.com>
When setting this property, you must set alternate interrupt number in
the 'interrupts' property.

@@ -50,6 +50,9 @@ Optional properties:
- clocks: Must contain a reference to the functional clock. The property is
mandatory if the hardware implements a controllable functional clock for
the GPIO instance.
+ - use-alternative-interrupt: Use 'alternative' GPIO interrupt instead
+ of 'normal' GPIO interrupt. When you specify this property, you must
+ also change the 'interrupts' DT property.
