[PATCH 1/2] ASoC: dt-bindings: fsl,audmix: Add support for i.MX952 platform

[Shengjiu Wang]

The specific feature for AUDMIX on i.MX952 is that it can be bypassed,
so add fsl,amix-bypass property for this feature, besides this there is
no power domain defined on i.MX952, so make power-domains to be
dedicated to i.MX8QM.

Need judgement why need 'fsl,amix-bypass', like difference board design
will use bypass or not.

I don't understand why device AUDMIX would have property saying AUDMIX
(so itself) can by bypassed. If you bypass the device itself, what do
you configure here?

fsl,amix-bypass: false

Not sure what you want to say here, but disallowing properties is shown
in example-schema (:false).

The case is that the SAI interface is connected to AUDMIX,  but AUDMIX can also
be bypassed by hardware configuration.

Yes, adding this property in the AUDMIX module looks strange.  Another
choice is to
add this property in the SAI binding document.  Is this better?

Not sure, but certainly it does not look like a property of AUDMIX.

I assume you acknowledge all other comments.

I will move the property to the SAI binding document, then please
have a review.  As this change, the binding document will be updated, for
the comments to use the example-schema (:false) will be adopted if needed.

[PATCH 2/2] ASoC: fsl_audmix: Add support for i.MX952 platform

[Shengjiu Wang]

Add compatible string to support AUDMIX on i.MX952

The audmix module can be bypassed so that SAI signals go directly to
external pin, which makes the SAI function independent with AUDMIX.
Add struct fsl_audmix_soc_data for this soc difference.
