in DTS file.

The register bit is 7, but the clock ID in the Tegra CAR DT binding is
96 for UART2 or 97 for VFIR. This was due to there being 1 clock bit and
2 separate IP block reset bits, or the other way around, so we highlight
the issue by assigning different clock IDs. See the comment before the
list of clock IDs in the binding document.

Aaha, I missed the Documentation part. I was looking for DT entry only
found this.
