Hi, I am using LS2085 processor in which IIC2_SCL and SDHC_CD_B pins are multiplexed together. I want to use both of these interfaces IIC and well as SDHC.

SDHC application is for booting purpose while IIC2 is used for  DDRs and retimers. My confusion is that will SDHC interface work without using SDHC_CD_B pin since

I am using it as IIC CLK line? I was also planning to use some GPIO to work as SDHC_CD pin, but I am not sure this will work because I am using SDHC for boot purpose

and GPIOs will not be detected before UBOOT.
