Hi,
We are working on agx xavier industrial on our custom board with R35.6.1 and would like to port a non-removed ufs device(KIOXIA THGJFGT1T45BAB8).
Please see the changes and schematic below.

};
After flashing the changed OS, I see messages below in dmesg.

We have confirm VCCQ_UFS and VCC_UFS are all on.
Did I miss anything?
