This driver doesn't depend on NVMEM, as in function mtk_thermal_get_calibration_data(), the calibration params are initialized with default values and if no "calibration-data" cell was found, it will return 0 and simply go on with probing... and this is because not all SoCs need calibration data from eFuses. If you check carefully, the original entry says "NVMEM || NVMEM=n". Please drop the NVMEM dependency from this config entirely. > + depends on RESET_CONTROLLER While at it, can you please also drop the dependency for RESET_CONTROLLER? I know it was present on the original config entry, but that's wrong, as the driver doesn't strictly require resets, as it uses device_reset_optional(). Regards, Angelo
Hi Angelo, Nice to hear from you again. Understood. The changes you asked for will be implemented in the v10 of this series. It will be sent very soon, I'm still working on Daniel's review too. Thank you for the review!
