of_get_regulator_init_data - extract regulator_init_data structure info : device requesting for regulator_init_data

Populates regulator_init_data structure by extracting data from device tree node, returns a pointer to the populated struture or NULL if memory alloc fails.

of_regulator_match - extract multiple regulator init data from device tree. : device requesting the data : parent device node of the regulators : match table for the regulators : number of entries in match table

This function uses a match table specified by the regulator driver to parse regulator init data from the device tree. is expected to contain a set of child nodes, each providing the init data for one regulator. The data parsed from a child node will be matched to a regulator based on either the deprecated property regulator-compatible if present, or otherwise the child node's name. Note that the match table is modified in place.

Returns the number of matches found or a negative error code on failure.
