From 205321f0927ad2303e7f71767d402e0ff36a9a87 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Thu, 10 Nov 2016 10:59:15 +0530 Subject: regulator: lp873x: Add support for populating input supply In order to have a proper topology of regulators for a platform, each registering regulator needs to populate supply_name field for identifying its supply's name. Add supply_name field for lp873x regulators.
