This commit introduces the PMIC uclass implementation. It allows providing the basic I/O interface for PMIC devices. For the multi-function PMIC devices, this can be used as I/O parent device, for each IC's interface. Then, each PMIC particular function can be provided by the child device's operations, and the child devices will use its parent for read/write by the common API. Core files: - 'include/power/pmic.h' - 'drivers/power/pmic/pmic-uclass.c' The old pmic framework is still kept and is independent. For more detailed informations, please look into the header file. Changes: - new uclass-id: UCLASS_PMIC - new config: CONFIG_DM_PMIC Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org>
