 * _omap_bandgap_write_threshold() - helper to update TALERT t_cold or t_hot

 * @bg_ptr: struct omap_bandgap pointer

 * @id: bandgap sensor id

 * @val: value (mCelsius) of a new threshold

 * @hot: desired threshold to be updated. true if threshold hot, false if

 *       threshold cold

 *

 * It will update the required thresholds (hot and cold) for TALERT signal.

 * This function can be used to update t_hot or t_cold, depending on @hot value.

 * Validates the mCelsius range and update the requested threshold.

 * Call this function only if bandgap features HAS(TALERT).
