This patchset adds gpio support for Actions Semi S900 SoC by extending the pinctrl driver. There were previous patches submitted for adding a standalone gpio driver based on gpiolib. But later on it has been realised that the gpio functionality is closely tied with pinctrl subsystem for this OWL family processors. So, having a separate gpio driver will make it hard to add further functionalities in future. Hence, we decided to drop the previous patches below adding a standalone gpio support:
