Signed-off-by: Karel Balej --- Notes: v6: - Remove all definitions (now present in the header). v5: - Add remaining regulators. - Clean up includes. - Address Mark's feedback: - Use dedicated regmap config. RFC v4: - Initialize regulators regmap in the regulators driver. - Register all regulators at once. - Drop regulator IDs. - Add missing '\n' to dev_err_probe message. - Fix includes. - Add ID table. RFC v3: - Do not have a variable for each regulator -- define them all in the pm886_regulators array. - Use new regulators regmap index name. - Use dev_err_probe. RFC v2: - Drop of_compatible and related code. - Drop unused include. - Remove some abstraction: use only one regmap for all regulators and only mention 88PM886 in Kconfig description. - Reword commit
