nrf5340 128MHz & SPI 32 MHz

[tcube]

Hello,

I need a SPI running at maximum SPI (32MHz).

My understanding is to have a 32 MHz SPI, I need a core running at 128MHz.

What is the correct way to configure the core clock: (Device Tree? KConfig? nrfx lib?

Thanks

Thanks Hakon,

I've got the qspi running in dual mode now.

My overlay changes are 

&qspi{
    status = "okay";
    /delete-node/ mx25r6435f@0;
    w25q64: w25q64jq@0 {
        compatible = "nordic,qspi-nor";
		reg = < 0x0 >;
        writeoc = "pp";
        readoc = "read2io";
        sck-frequency = < 33000000 >;
        jedec-id = [ EF 40 17 ];
        size = < 0x4000000 >;
    };
};
/ {
    aliases {
        
        /delete-property/ spi-flash0;
        qspi-flash64 = &w25q64;
    };
};
