1.1.1

Software Environment

Driver discussed in this document is designed based on Linux Kernel 2.6.32 and Android 2.3.

Due to the practicality, this document will focus on the overall architecture and BUCK / LDO control section.

1.1.2

Hardware Environment

Driver discussed in this document can run on MT6573 EVB SOC: MT6573

1.2

Functionality

FO

The PMU driver’s main functionality is: (1) 4 BUCK and 13 LDO turn on / off functions for PM API (2) 4 BUCK and 13 LDO voltage setting functions for PM API (3) Charger plug in / out and type detection. (4) Internal used functions.
