* IBM Powerpc Virtual Accelerator Switchboard (VAS) VAS is a hardware mechanism that allows kernel subsystems and user processes to directly submit compression and other requests to Nest accelerators (NX) or other coprocessors functions. Required properties: - compatible : should be "ibm,vas". - ibm,vas-id : A unique identifier for each instance of VAS in the system - reg : Should contain 4 pairs of 64-bit fields specifying the Hypervisor window context start and length, OS/User window context start and length, "Paste address" start and length, "Paste window id" start bit and number of bits) Example: vas@6019100000000 { compatible = "ibm,vas", "ibm,power9-vas"; reg = <0x6019100000000 0x2000000 0x6019000000000 0x100000000 0x8000000000000 0x100000000 0x20 0x10>; name = "vas"; ibm,vas-id = <0x1>; };
