There's no reason to have "status" properties in examples. "okay" is the
default, and "disabled" turns off some schema checks ('required'
specifically).
Enabling qca,ar71xx causes a warning, so let's fix the node names:

|
The audio support on the board is using pcm3168a codec connected to McASP10
|
|
serializers in parallel setup.
|
|
The pcm3168a SCKI clock is sourced from j721e AUDIO_REFCLK2 pin.
|
|
In order to support 48KHz and 44.1KHz family of sampling rates the parent
|
|
clock for AUDIO_REFCLK2 needs to be changed between PLL4 (for 48KHz) and
|
|
PLL15 (for 44.1KHz). The same PLLs are used for McASP10's AUXCLK clock via
|
|
different HSDIVIDER.
|
|
|
|
Clocking setup for j721e:
|
|
48KHz family:
|
|
PLL4 ---> PLL4_HSDIV0 ---> MCASP10_AUXCLK ---> McASP10.auxclk
|
|
|-> PLL4_HSDIV2 ---> AUDIO_REFCLK2 ---> pcm3168a.SCKI
|
|
|
|
44.1KHz family:
|
|
PLL15 ---> PLL15_HSDIV0 ---> MCASP10_AUXCLK ---> McASP10.auxclk
|
|
|-> PLL15_HSDIV2 ---> AUDIO_REFCLK2 ---> pcm3168a.SCKI
|
|
|
|
Clocking setup for j7200:
|
|
48KHz family:
|
|
PLL4 ---> PLL4_HSDIV0 ---> MCASP0_AUXCLK ---> McASP0.auxclk
|
|
|-> PLL4_HSDIV2 ---> AUDIO_REFCLK2 ---> pcm3168a.SCKI
