Re: [alsa-devel] [PATCH 6/6] ASoC: fsl: check property 'compatible' for the machine name

The ARM machines really shouldn't be using the bindings that PowerPC is using for the machine as they conflate the machine driver with the SSI binding. The idiom for new systems is that machine drivers should be first class devices in the device tree referencing the SSI and CODEC.

Where is this documented?

I don't remember participating in the discussion for this new binding.

The current bindings should be preserved for existing systems of course.

There's no reason we can't update the PowerPC device trees.
