U-Boot Pmic drivers (Updated 15-Dec-14)
U-Boot provides a framework for pmic drivers. Details can be found in:
doc/README.power-framework
Since the driver-model is used, and boards/subsystems are moving to it, there is a need for update the PMIC framework.
The implementation
The implementation assumptions:
- will base on driver-model
- use of the device-tree
- one uclass per functionality
- extend the user interface
The work status
December 2014
Resume the work on pmic framework after some break. Now the I2C and SPI subsystems provides support for the driver-model, so the background is done.
October 2014
The first version of new PMIC Framework was send to list. Is available also on
git-hub. And the conception was presented during the talk on U-Boot mini summit Düsseldorf 2014(ELCE 2014). The presentation can be found
here.
This site will be updated after sending the next patchset.
