[PATCHv3 4/6] omap3: pmic: add API to get common SMPS regulators

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

 



omap3_pmic_get_smps_config can now be used to get regulator configuration
for MPU and CORE SMPS regulators. This should be expanded later to add IVA
SMPS regulator for OMAP4.
