From 5b1ada83bae7d689cf1fe76eb1bdd058ea84a97c Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 5 Dec 2013 00:29:57 +0000 Subject: [PATCH] regulator: gpio: Don't require a regulator-type property Since essentially all GPIO controlled regulators are voltage regulators make the regulator-type property optional, defaulting to voltage.
