/*
 * TODO:
 *
 * Most vendors connect the surr-out of ad1980/ad1985 codecs to the
 * line-out jack. So far we haven't found which vendors don't
 * do that. So we assume that all vendors swap the surr-out
 * and the line-out outputs. So we need swap the two outputs.
 *
 * Historically we internally processed the "ad198x-swap-output"
 * property. If someday some vendors do not swap the outputs, we would
 * set "ad198x-swap-output = 0" in the driver.conf file, and unload
 * and reload the driver (or reboot).
 *
 * TODO:
 *
 * Since we don't have access (at present) to any such systems, we have
 * not implemented this swapping property.  Once we can test it, we will
 * add it.  This is noted as CR 6819556.
 *
 * The old code did this:
 *
 *  if (ddi_prop_get_int(DDI_DEV_T_ANY, statep->dip,
 *      DDI_PROP_DONTPASS, "ad198x-swap-output", 1) == 1) {
 *      statep->swap_out = B_TRUE;
 *      (void) audioixp_read_ac97(statep, CODEC_AD_REG_MISC, &tmp);
 *      (void) audioixp_write_ac97(statep,
 *          CODEC_AD_REG_MISC,
 *          tmp | AD1980_MISC_LOSEL | AD1980_MISC_HPSEL);
