[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tomas Novotny <tomas@xxxxxxxxxx>

Hi all,

here is a third version of a series to use regulator framework, add an
option to set external reference and to add devicetree support for
mcp4725/6.

Third version fixes mainly small bits found in the previous version.

Series is tested on MCP4726 on device tree platform.

Changes since v2:
- whitespace fix of two consecutive lines between patches (it affects
  already applied patch)
- abort probe instead of recovery in case of invalid configuration
- use local variable instead of allocation for platform data
- move unrelated comment fix to the new patch
- add ack from Rob
- fix doubled space in an assignment
- add documentation for the struct mcp4725_platform_data
- move the documentation patch forward because it is referenced in struct
  mcp4725_platform_data now
 
Changes since v1:
- add the first patch
- use regulator framework
- fix printf argument (%u instead of %d)
- add parenthesis to make expression more clear
- fix typo in documentation (Microchpip)
- move vref configuration from probe function to new mcp4726_set_cfg
