Raul E Rangel dfe3a2fcfc soc/amd/{common,cezanne}: Add uPEP device ... The uPEP device is required to support S0i3. The device has been written in ASL to make it easier to read and maintain. The device constraints are purely informational. We use a dummy constraint like the Intel platforms to keep both linux and Windows functional. In order for this device to be used by the linux kernel the ACPI_FADT_LOW_PWR_IDLE_S0 flag must be set. So including it unconditionally doesn't cause any problems. The AMD Modern Standby BIOS Implementation Guide defines two UUIDs, one for getting the device constraints, and one for handling notifications. This differs from the Intel specification and the linux driver implementation. For this reason I haven't implemented any of the notification callbacks yet.
