Subject: [PATCH v2 05/13] extcon: ptn5150: Use generic "interrupts" property
Date: Mon, 17 Aug 2020 09:00:01 +0200	[thread overview]
Message-ID: <20200817070009.4631-6-krzk@kernel.org> (raw)
In-Reply-To: <20200817070009.4631-1-krzk@kernel.org>

Interrupts do not have to be always GPIO based so instead of expecting
"int-gpios" property and converting the GPIO to an interrupt, just
accept any interrupt via generic "interrupts" property.

Keep support for old "int-gpios" for backward compatibility.
