[PATCH 2/5] cpufreq: ti: update OPP table for AM62Px SoCs

From: Bryan Brattlof
Date: Wed Jun 12 2024 - 12:43:45 EST


More speed grades for the AM62Px SoC family have been defined which
unfortunately no longer align with the AM62x table. So create a new
table with these new speed grades defined for the AM62Px
