1i.MX CPUFreq-DT OPP bindings2================================3 4Certain i.MX SoCs support different OPPs depending on the "market segment" and5"speed grading" value which are written in fuses. These bits are combined with6the opp-supported-hw values for each OPP to check if the OPP is allowed.7 8Required properties:9--------------------10 11For each opp entry in 'operating-points-v2' table:12- opp-supported-hw: Two bitmaps indicating:13 - Supported speed grade mask14 - Supported market segment mask15 0: Consumer16 1: Extended Consumer17 2: Industrial18 3: Automotive19 20Example:21--------22 23opp_table {24 compatible = "operating-points-v2";25 opp-1000000000 {26 opp-hz = /bits/ 64 <1000000000>;27 /* grade >= 0, consumer only */28 opp-supported-hw = <0xf>, <0x3>;29 };30 31 opp-1300000000 {32 opp-hz = /bits/ 64 <1300000000>;33 opp-microvolt = <1000000>;34 /* grade >= 1, all segments */35 opp-supported-hw = <0xe>, <0x7>;36 };37}38
