Subject: [PATCH 6/6] regulator: anatop: set default voltage selector for pcie
Date: Wed, 12 Apr 2017 09:58:47 +0800	[thread overview]
Message-ID: <1491962327-12477-6-git-send-email-aisheng.dong@nxp.com> (raw)
In-Reply-To: <1491962327-12477-1-git-send-email-aisheng.dong@nxp.com>

Set the initial voltage selector for vddpcie in case it's disabled
by default.

This fixes the below warning:
20c8000.anatop:regulator-vddpcie: Failed to read a valid default voltage selector.
anatop_regulator: probe of 20c8000.anatop:regulator-vddpcie failed with error -22
