This PMIC is used with SoCs which need a combination of BUCKs and LDOs. The driver supports probing and basic register access. It supports the standard device tree binding and supports driver model. A regulator driver can be provided also. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>
