Subject: [PATCH v3 2/3] dt-bindings: gpio: vf610: add optional 'ngpios'
Date: Wed, 17 Jan 2024 09:32:50 +0100 [thread overview]
Message-ID: <20240117083251.53868-3-hector.palacios@digi.com> (raw)
In-Reply-To: <20240117083251.53868-1-hector.palacios@digi.com>
Some SoCs, such as i.MX93, don't have all 32 pins available
per port. Allow optional generic 'ngpios' property to be
specified from the device tree and default to 32 if the
property does not exist.
