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?
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?
