From 6625d9d297f28741d42a4ba712338a05f7464bd6 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 19 Jul 2013 13:06:22 +0800 Subject: [PATCH] regulator: 88pm800: Add missing n_voltages setting for bucks Some regulator APIs are broken if n_voltages setting is not set. e.g. regulator_count_voltages(), regulator_list_voltage(), and regulator_can_change_voltage() do not work if n_voltages setting is missing.
