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 Signed-off-by: Bryan Brattlof <bb@ti.com> --- drivers/cpufreq/ti-cpufreq.c | 35 ++++++++++++++++++++++++++++++++++- 1 file changed, 34 insertions(+), 1 deletion(-)
