From d5ec96357d743288bd03a685defd586ad35d351e Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 23 Mar 2012 16:49:22 +0800 Subject: [PATCH] regulator: Convert pcap-regulator to set_voltage_sel After converting to set_voltage_sel, we can remove the workaroud of getting the best match voltage for V1. The core will iterate through the whole voltage table and find the best match for us.
