While it's true that, generally, the T-PHY V3 does not support the slew calibration process, some minor versions of it actually do, moreover, some SoCs may not support this even though the version of the PHY IP does. The reference clock and rate coefficient parameters are used only for slew calibration: move those to platform data, then document and change the checks in hs_slew_rate_calibrate() to perform the calibration only if: - EYE value was not supplied (pre-calculated calibration); and - Slew reference clock value is present (not zero); and - Slew coefficient is present (not zero). Moreover, change the probe function to always check if both the slew reference clock and coefficient properties are present and, if not, assign the value from platform data (which, as reminder, if not added means that it's zero!), instead of checking the PHY IP version.
