The BeagleV Starlight v0.9 board[1] doesn't have the IRQB line routed to the SoC, but it is still useful to be able to reach the PMIC over I2C for the other functionality it provides such as GPIOs and regulator settings.

List of child nodes that specify the regulator initialization data.
|
|
Child nodes must be named after their hardware counterparts:
|
|
buck[1-6], ldoa[1-3], swa1, swb[1-2], and vtt.
|
|
Each child node is defined using the standard binding for regulators and
|
|
the optional regulator properties defined below.
