Subject: [PATCH] regulator: axp20x: Add support for AXP22X regulators
|
|
|
|
Add AXP22X regulator definitions and variant id associations.
|
|
This introduces a new "switch" type output for one of the regulators.
|
|
It is a switchable secondary output of one regulator, with the same
|
|
voltage level as the primary output.
