OPP: Support more speed grades and silicon revisions

[PATCH 0/3] OPP: Support more speed grades and silicon revisions

Posted by Judith Mendez 1 month, 2 weeks ago

As the AM62x, AM62ax, and AM62px SoC families mature, more speed
grades are established and more silicon revisions are released. This
patch series adds support for more speed grades on AM62Px SoCs in
ti-cpufreq. Also allow all silicon revisions across AM62x, AM62Px,
and AM62Ax SoCs to use the already established OPPs and instead determine
approprate OPP application with speed grade efuse parsing.

Also fix 1GHz OPP which according to device datasheet [0], also supports
speed grade "O".

Applied. Thanks.
