This node exports the per-chip pstate table properties to kernel.
Example:
- occ@7ffddf8000 {
ibm,pstate-vdds = [45 45 46 46 46 47 48 49 4a 4b 4c 4d 4f 50 51 52 53 54 55 57 58 59 5a 5b 5c 5d 5e 5f 5f 60 61 62 63 64 65 65 66 67 68 69 6a 6a 6b 6c 6d 6e 6f 70 70 71]; ibm,chip-id = <0x1>; phandle = <0x100003b8>; ibm,pstate-vcss = [3b 3d 3f 41 42 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f 50 50 51 52 53 54 55 56 56 57 57 58 58 59 59 5a 5a 5b 5b 5c 5c 5d 5d 5e 5e 5f 5f 60 60 61 61 62 62]; reg = <0x7f 0xfddf8000 0xb98>;
};
This property denotes the ID of chip to which OCC belongs to.
This tuple gives the statring address of the OPAL data in HOMER and the size of the OPAL data.
- The top-level /ibm,opal/power-mgt contains :
#size-cells = <1> #address-cells = <2>
These properties list a voltage-identifier of each of the pstates listed in ibm,pstate-ids for the Vcs and Vdd values used for that pstate in that chip. Each VID is a single byte.
