My reading is that this patch reverses the usage of module and regaddr.
F.e. the following hunk:

@@ -553,11 +554,11 @@ static int _sync_pll_output(struct idtcm *idtcm,

	val = SYNCTRL1_MASTER_SYNC_RST;

	/* Place master sync in reset */
	err = idtcm_write(idtcm, 0, sync_ctrl1, &val, sizeof(val));
	err = idtcm_write(idtcm, sync_ctrl1, 0, &val, sizeof(val));
	if (err)
		return err;

	err = idtcm_write(idtcm, 0, sync_ctrl0, &sync_src, sizeof(sync_src));
	err = idtcm_write(idtcm, sync_ctrl0, 0, &sync_src, sizeof(sync_src));
	if (err)
		return err;

If that is really intended I think it needs to be explained, or possibly a
separate patch.
