 * offset measurements made with a CMU200 RF tester:
 *
 * Psi_sta_inv: 3462
 * Psi_st: 15
 * Psi_st_32: 992326
 * Psi_st_inv: 4328
 *
 * The following AFC slope number is the closest OsmocomBB-style afc_slope
 * integer corresponding to these Psi numbers; the true value is somewhere
 * between 454 and 455.
 *
 * This AFC slope setting is expected to be correct for both Openmoko and

 * by Openmoko.
