From 0bc20bba357f18a0e52f45afc452d0b69cf06f76 Mon Sep 17 00:00:00 2001 From: Todd Fischer Date: Mon, 5 Apr 2010 20:23:57 -0600 Subject: mfd: Add tps6507x board data structure Add mfd structure which refrences sub-driver initialization data. For example, for a giving hardware implementation, the voltage regulator sub-driver initialization data provides the mapping betten a voltage regulator and what the output voltage is being used for.
