The LP873X chip is a power management IC for Portable Navigation Systems
and Tablet Computing devices. It contains the following components:
- Regulators.
- Configurable General Purpose Output Signals(GPO).
PMIC interacts with the main processor through i2c. PMIC has
couple of LDOs(Linear Regulators), couple of BUCKs (Step-Down DC-DC
Converter Cores) and GPOs(General Purpose Output Signals).
The regulator patch is already queued:
http://marc.info/?l=linux-kernel&m=146298767110771&w=2
DT patch also queued.
Hence posting the remaining patches of the series with
the comments fixed on mfd driver.
Changes in v8:
Defined Macros for hardcoded bit definitions in gpio driver.
Added Mark's ack for the regulator config change patch.
Chages in v7:
Reverted the dependency on

Changes in v6:
Series depends on: http://www.gossamer-threads.com/lists/linux/kernel/2457552
probe_new used.
Chnages in v4:
Added GPO driver support.
