done.

I believe this naming came from FSL's mipi csi-2 driver. It is the "hsi_tx"
clock (presumably for the MIPI HSI controller) whose parents are selected
by the CDCDR register as PLL3_120M or PLL2_PFD2. I have no clue whether
this is indeed also used as the clock for the MIPI CSI-2 D-PHY, but
according
to FSL naming convention it might be.
