From 4f2352cf52738bd980713e85e8ae631c6c3a8feb Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Thu, 31 Jul 2014 14:31:05 +0200 Subject: [PATCH] regulator: tps65090: Set voltage for fixed regulators According to the tps65090 data manual [0], the DCDC1 and DCDC2 step-down converters and the LDO's have a fixed output voltage. Add this information to the driver since these fixed regulators can be used as parent input supply for switches that don't have an output voltage defined. So the regulator core needs to fetch the FET parent output voltage if the child voltage is queried.
