Dear NXP team,

in the file imx8mm.dtsi, the opp-table reports the same 3 operating points documented in tabled 10 of the SoC datasheet: 1.2, 1.6 and 1.8 GHz

However, in the file clk-pll14xx.c, the table imx_pll1416x_tbl reports also additional clock frequencies.

Can these additional frequencies be introduced in the opp-table to farther reduce the clock frequency ?

If yes, which values should be used for the properties opp-microvolts, opp-supported-hw, clock-latency-ns ?

Thanks

Best Regards

Pier
