ROHM Power Management IC BD2657 device driver.

Linux:

Device driver for BD2657 is being worked on.

The ROHM BD2657 Power Management IC is intended to be used for systems powered by one Li-Ion or Li-Ion polymer battery cell, or by an input from 2.85 V to 5.5 V. The device provides 4 buck converters supporting dynamic voltage scaling. Programmable output voltage, sequencing and power state control support a wide variety of processors and system implementations. The BD2657 also provides 2 general purpose outputs and a power button support.

You can check the bd2657-dev branch for the unstable development version. Please note the branch can be rebased/moved/edited without a warning.

configs

* CONFIG_MFD_ROHM_BD2657 for BD2657 core
* CONFIG_REGULATOR_BD2657 for regulator control
