[Debian] How to read/write mmc related register in mmc driver?

Hi guys,

I want to read/write mmc register (0x14A0/0x14A09/0x14A46), but I cannot find the related function in /kernel/driver/mmc driver.
Does anyone know could we read/write mmc register in current Debian on DB410c?


Best regards,

Hi all,

I still have the same question,
I want to check L11 voltage value when initial SD card procedure.
How can I read/write the register?
