From ad0b40fee4081490676b26ec4fb2205607116eaf Mon Sep 17 00:00:00 2001 From: Alban Bedel Date: Tue, 20 May 2014 12:14:02 +0200 Subject: regulator: tps6586x: Prepare supporting fixed regulators Add the required definitions and macros to allow easily adding fixed regulators. This required for the TPS658640 that doesn't allow setting the LDO_RTC output voltage.
