Rohm power management IC drivers for Linux kernel.
This project is maintained by RohmSemiconductor
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.
* CONFIG_MFD_ROHM_BD2657 for BD2657 core
* CONFIG_REGULATOR_BD2657 for regulator control
* CONFIG_GPIO_BD2657 for GPIO control
