Signed-off-by: Wenyou Yang Acked-by: Rob Herring Acked-by: Lee Jones --- Changes in v10: - update the example, due to the subdevices are not regarded as a child node. Changes in v9: None Changes in v8: None Changes in v7: - collect Acked-by from Lee Jones Changes in v6: - change the regulator name. Changes in v5: None Changes in v4: None Changes in v3: - fix the tabbing errors in Example. - use "pmic@5b" label, not "act8945a@5b" in Example. - collect Acked-by from Rob. Changes in v2: - use more specific label in Example. - add pmic and charger nodes in Example.
