Merge branch 'pm-opp'
Merge OPP (Operating Performance Points) changes for 6.13-rc1: - Describe opp-supported-hw property for ti-cpu (Dhruva Gole). - Remove unused declarations from the OPP header file (Zhang Zekun). * pm-opp: dt-bindings: opp: operating-points-v2-ti-cpu: Describe opp-supported-hw OPP: Remove unused declarations in header file

+ 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.
