- description:
The revision of the SoC the OPP is supported by.
This can be easily obtained from the datasheet of the
part being ordered/used. For example, it will be 0x01 for SR1.0
- description:
The eFuse bits that indicate the particular OPP is available.
The device datasheet has a table talking about Device Speed Grades.
This table is to be sorted with only the unique elements of the
MAXIMUM OPERATING FREQUENCY starting from the first row which
tells the lowest OPP, to the highest. The corresponding bits
need to be set based on N elements of speed grade the device supports.
So, if there are 3 possible unique MAXIMUM OPERATING FREQUENCY
in the table, then BIT(0) | (1) | (2) will be set, which means
the value shall be 0x7.
