2020-09-11ASoC: dt-bindings: ti, j721e-cpb-audio: Document support for j7200-cpbPeter Ujfalusi1-22/+70
j721e or j7200 SOM can be attached to the same Common Processor Board (CPB) With the j7200 SOM only the 48KHz family parent clock is available and McASP0 is used for the audio.

2020-08-14dt-bindings: Remove more cases of 'allOf' containing a '$ref'Rob Herring1-4/+2
Another wack-a-mole pass of killing off unnecessary 'allOf + $ref' usage. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org>
2020-07-01ASoC: dt-bindings: Add documentation for TI j721e EVM (CPB and IVI)Peter Ujfalusi1-0/+95
The audio support on the Common Processor Board board is using pcm3168a codec connected to McASP10 serializers in parallel setup. The Infotainment board plugs into the Common Processor Board, the support of the extension board is extending the CPB audio support by adding the two codecs on the expansion board. The audio support on the Infotainment Expansion Board consists of McASP0 connected to two pcm3168a codecs with dedicated set of serializers to each. The SCKI for pcm3168a is sourced from j721e AUDIO_REFCLK0 pin.
