What exactly are those requirements? IIRC dbri has a rather weird
maximum block size:
static int
dbri_round_blocksize(void *hdl, int bs, int mode,
			const audio_params_t *param)
{

	/*
	 * DBRI DMA segment size can be up to 0x1fff, sizes that are not powers
	 * of two seem to confuse the upper audio layer so we're going with
	 * 0x1000 here
	 */
	return 0x1000;
}

That said, I'll take care of potential fallout with the dbri driver.

have fun
Michael
