15 2 - CPU capacity definition
38 by the frequency (in MHz) at which the benchmark has been run, so that
39 DMIPS/MHz are obtained.  Such values are then normalized w.r.t. the highest
43 3 - capacity-dmips-mhz
46 capacity-dmips-mhz is an optional cpu node [1] property: u32 value
47 representing CPU capacity expressed in normalized DMIPS/MHz. At boot time, the
51 capacity-dmips-mhz property is all-or-nothing: if it is specified for a cpu
55 mhz values (normalized w.r.t. the highest value found while parsing the DT).
62 The capacities-dmips-mhz or DMIPS/MHz values (scaled to 1024)
69 	#address-cells = <2>;
128 		capacity-dmips-mhz = <1024>;
139 		capacity-dmips-mhz = <1024>;
150 		capacity-dmips-mhz = <578>;
161 		capacity-dmips-mhz = <578>;
172 		capacity-dmips-mhz = <578>;

195 Example 2 (ARM 32-bit, 4-cpu system, two clusters,
196 	   cpus 0,1@1GHz, cpus 2,3@500MHz):
197 capacities-dmips-mhz are scaled w.r.t. 2 (cpu@0 and cpu@1), this means that first
198 cpu@0 and cpu@1 are twice fast than cpu@2 and cpu@3 (at the same frequency)
208 		capacity-dmips-mhz = <2>;
215 		capacity-dmips-mhz = <2>;
218 	cpu2: cpu@2 {
222 		capacity-dmips-mhz = <1>;
229 		capacity-dmips-mhz = <1>;
