From 0d1cbc489e988f98e28c176c26d25d4ceacd8e5b Mon Sep 17 00:00:00 2001 From: Tirupathi Reddy Date: Fri, 10 Mar 2017 15:55:59 +0530 Subject: [PATCH] regulator: core: Fix voltage change propagations to supply regulators Some regulators support get_voltage and some support get_voltage_sel operations. Do voltage change propagation only when the current regulator has a minimum dropout voltage specified or if the current regulator lacks both get_voltage and get_voltage_sel operations.
