Are you saying that every DT for a system doing audio on a PowerPC system has to manually specify the depth of the FIFO on the silicon?
Only for SSI devices.
That doesn't sound particularly sensible, and I had been under the impression that DT systems had a better way of coping with this.
The whole point behind having a device tree is to specify device information that cannot be probed. So every piece of information in the DT is something that the driver needs to be told because there is no way to query the hardware.
