Hi Marek,

The TMU TASR, TCALIVn, TRIM registers must be explicitly programmed with
calibration values in OCOTP. Add the OCOTP calibration values phandle so
the TMU driver can perform this programming.
The MX8MM/MX8MN TMUv1 uses only one OCOTP cell, while MX8MP TMUv2 uses 4.
Is there any source for the fuse addresses? I can only find
OCOTP_OCOTP_HW_OCOTP_ANA1 and a calibration description in TMU section in the
IMX8MNRM Rev 2, but I can't find any fuse for imx8mm and imx8mp.
See 5/5 in this series, the offsets are pulled from U-Boot. The
documentation seems to be lacking in this case, I couldn't find anything
there either.
