The SCKI for pcm3168a is sourced from j721e AUDIO_REFCLK0 pin. In order to support 48KHz and 44.1KHz family of sampling rates the parent clock for AUDIO_REFCLK0 needs to be changed between PLL4 (for 48KHz) and PLL15 (for 44.1KHz). The same PLLs are used for McASP0's AUXCLK clock via different HSDIVIDER. Note: the same PLL4 and PLL15 is used by the audio support on the CPB! Clocking setup for 48KHz family: PLL4 ---> PLL4_HSDIV0 ---> MCASP10_AUXCLK ---> McASP10.auxclk | |-> MCASP0_AUXCLK ---> McASP0.auxclk | |-> PLL4_HSDIV2 ---> AUDIO_REFCLK2 ---> pcm3168a.SCKI |-> AUDIO_REFCLK0 ---> pcm3168a_a/b.SCKI Clocking setup for 44.1KHz family: PLL15 ---> PLL15_HSDIV0 ---> MCASP10_AUXCLK ---> McASP10.auxclk | |-> MCASP0_AUXCLK ---> McASP0.auxclk | |-> PLL15_HSDIV2 ---> AUDIO_REFCLK2 ---> pcm3168a.SCKI |-> AUDIO_REFCLK0 ---> pcm3168a_a/b.SCKI properties: compatible: items: - const: ti,j721e-cpb-ivi-audio model: $ref: /schemas/types.yaml#/definitions/string description: User specified audio sound card name ti,cpb-mcasp: description: phandle to McASP used on CPB $ref: /schemas/types.yaml#/definitions/phandle ti,cpb-codec: description: phandle to the pcm3168a codec used on the CPB $ref: /schemas/types.yaml#/definitions/phandle ti,ivi-mcasp: description: phandle to McASP used on IVI $ref: /schemas/types.yaml#/definitions/phandle ti,ivi-codec-a: description: phandle to the pcm3168a-A codec on the expansion board $ref: /schemas/types.yaml#/definitions/phandle ti,ivi-codec-b: description: phandle to the pcm3168a-B codec on the expansion board $ref: /schemas/types.yaml#/definitions/phandle clocks: items: - description: AUXCLK clock for McASP used by CPB audio - description: Parent for CPB_McASP auxclk (for 48KHz) - description: Parent for CPB_McASP auxclk (for 44.1KHz) - description: SCKI clock for the pcm3168a codec on CPB - description: Parent for CPB_SCKI clock (for 48KHz) - description: Parent for CPB_SCKI clock (for 44.1KHz) - description: AUXCLK clock for McASP used by IVI audio - description: Parent for IVI_McASP auxclk (for 48KHz) - description: Parent for IVI_McASP auxclk (for 44.1KHz) - description: SCKI clock for the pcm3168a codec on IVI - description: Parent for IVI_SCKI clock (for 48KHz) - description: Parent for IVI_SCKI clock (for 44.1KHz) clock-names: items: - const: cpb-mcasp-auxclk - const: cpb-mcasp-auxclk-48000 - const: cpb-mcasp-auxclk-44100 - const: cpb-codec-scki - const: cpb-codec-scki-48000 - const: cpb-codec-scki-44100 - const: ivi-mcasp-auxclk - const: ivi-mcasp-auxclk-48000 - const: ivi-mcasp-auxclk-44100 - const: ivi-codec-scki - const: ivi-codec-scki-48000 - const: ivi-codec-scki-44100 required: - compatible - model - ti,cpb-mcasp - ti,cpb-codec - ti,ivi-mcasp - ti,ivi-codec-a - ti,ivi-codec-b - clocks - clock-names additionalProperties: false examples: - |+ sound { compatible = "ti,j721e-cpb-ivi-audio"; model = "j721e-cpb-ivi"; ti,cpb-mcasp = <&mcasp10>; ti,cpb-codec = <&pcm3168a_1>; ti,ivi-mcasp = <&mcasp0>; ti,ivi-codec-a = <&pcm3168a_a>; ti,ivi-codec-b = <&pcm3168a_b>; clocks = <&k3_clks 184 1>, <&k3_clks 184 2>, <&k3_clks 184 4>, <&k3_clks 157 371>, <&k3_clks 157 400>, <&k3_clks 157 401>, <&k3_clks 174 1>, <&k3_clks 174 2>, <&k3_clks 174 4>, <&k3_clks 157 301>, <&k3_clks 157 330>, <&k3_clks 157 331>; clock-names = "cpb-mcasp-auxclk", "cpb-mcasp-auxclk-48000", "cpb-mcasp-auxclk-44100", "cpb-codec-scki", "cpb-codec-scki-48000", "cpb-codec-scki-44100", "ivi-mcasp-auxclk", "ivi-mcasp-auxclk-48000", "ivi-mcasp-auxclk-44100", "ivi-codec-scki", "ivi-codec-scki-48000", "ivi-codec-scki-44100"; }; |
