The imx412 has three regulators which depending on platform may need to be individually enabled. - dovdd - avdd - dvdd Existing code for an Intel platform doesn't appear to need to enable these rails directly. On my reference hardware, a Qualcomm Thundercomm RB5 some of these rails do need to be enabled individually. Add in the above named rails as optional in the YAML in the first patch along with code to switch them on in the second patch. Existing imx412 users should get dummy regulators populated which the regulator_bulk_enable()/regulator_bulk_disable() code can safely ignore.
