Wysocki" , Len Brown , Mika Westerberg , Dmitry Torokhov , Rob Herring , Kieran Bingham , open list List-Id: devicetree@vger.kernel.org There is an OF/ACPI function to obtain the driver data. We want to hide OF/ACPI details from the device drivers and abstract following the device family of functions.
