In the imx BSP release, imx8mn-ddr3l-evk (utilizing imx8mnul SoC) device file includes imx8mn.dtsi with no modifications that I can find to the a53_opp_table node. My understanding form the datasheet imx8mnul does not support 1.5GHz. Should this operating point be removed? Thank you.
checked with imx8mn ddr3l evk board schematic, which uses i.MX 8M Nano QuadLite,you don't need move the higher frequency from table, the driver would read the frequency from fuse firstly, would match the nearest frequency from table, if you have board, you can try it
