I also want to know how to set the actual clock frequency and what modifications are needed in the hardware and software parts.

Hello,

I guess you can reduce the clock in the dtb.

Yes, when I set the frequency to 12MHz, it initializes the SDIO card.
mmc0: new high speed SDIO card at address 0001

If I set the frequency to 50MHz, the SDIO card does not initialize.
mmc0: error -84 whilst initialising SDIO card

And I want to know how to set the actual clock frequency.
