Currently audio mclk uses a fixed clk of 11.2896MHz (multiple of 44.1kHz). Replace this fixed clk with the programmable versa3 clk that can provide the clocking to support both 44.1kHz (with a clock of 11.2896MHz) and 48kHz (with a clock of 12.2880MHz), based on audio sampling rate for playback and record. Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx> --- v1->v2: * Made Versa3 clock mapping as per HW manual and updated clocks property in codec_dai. * Replaced the node xtal->x1-clock and label x1_x2->x1 as x2 is a different crystal. * Updated clock-frequency = <400000> for i2c0 node in RZ/G2UL SMARC EVK. --- .../boot/dts/renesas/rz-smarc-common.dtsi | 14 +++++------ arch/arm64/boot/dts/renesas/rzg2l-smarc.dtsi | 20 ++++++++++++++++ arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi | 20 ++++++++++++++++ arch/arm64/boot/dts/renesas/rzg2ul-smarc.dtsi | 24 +++++++++++++++++++ 4 files changed, 71 insertions(+), 7 deletions(-) diff --git a/arch/arm64/boot/dts/renesas/rz-smarc-common.dtsi b/arch/arm64/boot/dts/renesas/rz-smarc-common.dtsi index a7594ba3a998..b7a3e6caa386 100644 --- a/arch/arm64/boot/dts/renesas/rz-smarc-common.dtsi +++ b/arch/arm64/boot/dts/renesas/rz-smarc-common.dtsi @@ -32,12 +32,6 @@ chosen { stdout-path = "serial0:115200n8"; }; - audio_mclock: audio_mclock { - compatible = "fixed-clock"; - #clock-cells = <0>; - clock-frequency = <11289600>; - }; - snd_rzg2l: sound { compatible = "simple-audio-card"; simple-audio-card,format = "i2s"; @@ -55,7 +49,7 @@ cpu_dai: simple-audio-card,cpu { }; codec_dai: simple-audio-card,codec { - clocks = <&audio_mclock>; + clocks = <&versa3 2>; sound-dai = <&wm8978>; }; }; @@ -76,6 +70,12 @@ vccq_sdhi1: regulator-vccq-sdhi1 { gpios-states = <1>; states = <3300000 1>, <1800000 0>; }; + + x1: x1-clock { + compatible = "fixed-clock"; + #clock-cells = <0>; + clock-frequency = <24000000>; + }; }; &audio_clk1 { diff --git a/arch/arm64/boot/dts/renesas/rzg2l-smarc.dtsi b/arch/arm64/boot/dts/renesas/rzg2l-smarc.dtsi index 68eab8e26bf2..c05acd70f1fa 100644 --- a/arch/arm64/boot/dts/renesas/rzg2l-smarc.dtsi +++ b/arch/arm64/boot/dts/renesas/rzg2l-smarc.dtsi @@ -105,6 +105,26 @@ &i2c3 { status = "okay"; + versa3: versa3@68 { + compatible = "renesas,5p35023"; + reg = <0x68>; + #clock-cells = <1>; + clocks = <&x1>; + + renesas,settings = [ + 80 00 11 19 4c 02 23 7f 83 19 08 a9 5f 25 24 bf + 00 14 7a e1 00 00 00 00 01 55 59 bb 3f 30 90 b6 + 80 b0 45 c4 95 + ]; + + assigned-clocks = <&versa3 0>, <&versa3 1>, + <&versa3 2>, <&versa3 3>, + <&versa3 4>, <&versa3 5>; + assigned-clock-rates = <24000000>, <11289600>, + <11289600>, <12000000>, + <25000000>, <12288000>; + }; + wm8978: codec@1a { compatible = "wlf,wm8978"; #sound-dai-cells = <0>; diff --git a/arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi b/arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi index 83fce96a2575..3c40b66b33b0 100644 --- a/arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi +++ b/arch/arm64/boot/dts/renesas/rzg2lc-smarc.dtsi @@ -121,6 +121,26 @@ &i2c2 { status = "okay"; + versa3: versa3@68 { + compatible = "renesas,5p35023"; + reg = <0x68>; + #clock-cells = <1>; + clocks = <&x1>; + + renesas,settings = [ + 80 00 11 19 4c 02 23 7f 83 19 08 a9 5f 25 24 bf + 00 14 7a e1 00 00 00 00 01 55 59 bb 3f 30 90 b6 + 80 b0 45 c4 95 + ]; + + assigned-clocks = <&versa3 0>, <&versa3 1>, + <&versa3 2>, <&versa3 3>, + <&versa3 4>, <&versa3 5>; + assigned-clock-rates = <24000000>, <11289600>, + <11289600>, <12000000>, + <25000000>, <12288000>; + }; + wm8978: codec@1a { compatible = "wlf,wm8978"; #sound-dai-cells = <0>; diff --git a/arch/arm64/boot/dts/renesas/rzg2ul-smarc.dtsi b/arch/arm64/boot/dts/renesas/rzg2ul-smarc.dtsi index 8eb411aac80d..dacf35c16648 100644 --- a/arch/arm64/boot/dts/renesas/rzg2ul-smarc.dtsi +++ b/arch/arm64/boot/dts/renesas/rzg2ul-smarc.dtsi @@ -20,6 +20,30 @@ &cpu_dai { sound-dai = <&ssi1>; }; +&i2c0 { + clock-frequency = <400000>; + + versa3: versa3@68 { + compatible = "renesas,5p35023"; + reg = <0x68>; + #clock-cells = <1>; + clocks = <&x1>; + + renesas,settings = [ + 80 00 11 19 4c 02 23 7f 83 19 08 a9 5f 25 24 bf + 00 14 7a e1 00 00 00 00 01 55 59 bb 3f 30 90 b6 + 80 b0 45 c4 95 + ]; + + assigned-clocks = <&versa3 0>, <&versa3 1>, + <&versa3 2>, <&versa3 3>, + <&versa3 4>, <&versa3 5>; + assigned-clock-rates = <24000000>, <11289600>, + <11289600>, <12000000>, + <25000000>, <12288000>; + }; +}; + &i2c1 { wm8978: codec@1a { compatible = "wlf,wm8978"; -- 2.25.1
