From: Serge Semin <Sergey.Semin@baikalelectronics.ru>
Port A of the DW GPIO controller may optionally have a debounce logic enabled if it was synthesized with that functionality enabled. In this case a dedicated reference clock should be declared in the node with corresponding "db" name presented in the clock-names property.
