Don't expect this driver to work on real hardware, but QEMU emulates it. -- Add fdt glue for ARM PrimeCell Advanced Audio CODEC interface (PL041). -- Add aaci at fdt, commented out for now. Driver should work (tm) but QEMU and my old Thinkpad can't seem to keep up. -- Fix two bugs: - Inverted test for fifo status in aaci_write_data - Return success from trigger_output (thanks nat) -- Enable aaci -- bus_space_write_multi_4 takes a count, not number of bytes. With this, audio works in qemu.
