i.MX CPUFreq-DT OPP bindings
================================
Certain i.MX SoCs support different OPPs depending on the "market segment" and
"speed grading" value which are written in fuses. These bits are combined with
the opp-supported-hw values for each OPP to check if the OPP is allowed.
Required properties:
--------------------
For each opp entry in 'operating-points-v2' table:
- opp-supported-hw: Two bitmaps indicating:
- Supported speed grade mask
- Supported market segment mask
0: Consumer
1: Extended Consumer
2: Industrial
3: Automotive
Example:
--------
opp_table {
compatible = "operating-points-v2";
opp-1000000000 {
opp-hz = /bits/ 64 <1000000000>;
/* grade >= 0, consumer only */
opp-supported-hw = <0xf>, <0x3>;
};
opp-1300000000 {
opp-hz = /bits/ 64 <1300000000>;
opp-microvolt = <1000000>;
/* grade >= 1, all segments */
opp-supported-hw = <0xe>, <0x7>;
};
}
