Many Motorola phones like droid 4 are using a custom PMIC called CPCAP or 6556002. We can support it's core features quite easily with regmap_spi and regmap_irq. The children of cpcap, such as regulators, ADC and USB, can be just regular device drivers and defined in the dts file. They get probed as we call of_platform_populate() at the end of our probe, and then the children can just call dev_get_regmap(dev.parent, NULL) to get the regmap.
