23.2.3 Driver Interface Details
Access to the Anatop regulator is provided through the API of the regulator core driver.
The Anatop regulator driver provides the following regulator controls:
• Seven LDO regulators.
• All of the regulator functions are handled by setting the appropriate Anatop hardware
register values. This is done by calling the regulator core APIs to access the Anatop
hardware registers.
23.2.4 Source Code Structure
The Anatop regulator driver is located in the regulator device driver directory:
<ltib_dir>/rpm/BUILD/linux/drivers/regulator
