[PATCH v2] ARM: S5PC210: add support for i2c PMICs on Universal_C210 board

Tue Feb 15 07:50:41 EST 2011
This patch adds basic definitions for MAX8952 & LP3974 (MAX8998
compatible) PMICs for UniversalC210 board. Power consumers for the
device drivers will be added later. These two PMICs occupy I2C5 bus.
