^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) ================================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) Certain i.MX SoCs support different OPPs depending on the "market segment" and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) "speed grading" value which are written in fuses. These bits are combined with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) the opp-supported-hw values for each OPP to check if the OPP is allowed.
