89  * U-Boot PMIC Framework
92  * UCLASS_PMIC - This is designed to provide an I/O interface for PMIC devices.
94  * For the multi-function PMIC devices, this can be used as parent I/O device

108  *   |_ PMIC device (READ/WRITE ops)           - UCLASS_PMIC
111  * We can find two PMIC cases in boards design:
114  * We bind a single PMIC device for each interface, to provide an I/O for
122  *   |_ the I2C/SPI driver should bind a device for pmic node:
123  *     |_ the PMIC driver should bind devices for its childs:
128  * The same for other device nodes, for multi-interface PMIC.
131  * Each PMIC interface driver should use a different compatible string.
133  * If a PMIC child device driver needs access the PMIC-specific registers,
135  * the parent pmic driver. Like in the example:
142  * To ensure such device relationship, the pmic device driver should also bind
