Along with it external audio clocks > were added. Board device tree could use it and update the frequencies. > > Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx> Reviewed-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx> Cheers, Biju > --- > > Changes in v3: > - none > > Changes in v2: > - none > > arch/arm64/boot/dts/renesas/r9a08g045.dtsi | 96 ++++++++++++++++++++++ > 1 file changed, 96 insertions(+) > > diff --git a/arch/arm64/boot/dts/renesas/r9a08g045.dtsi b/arch/arm64/boot/dts/renesas/r9a08g045.dtsi > index be8a0a768c65..24c6388cd0d5 100644 > --- a/arch/arm64/boot/dts/renesas/r9a08g045.dtsi > +++ b/arch/arm64/boot/dts/renesas/r9a08g045.dtsi > @@ -14,6 +14,22 @@ / { > #address-cells = <2>; > #size-cells = <2>; > > + audio_clk1: audio-clk1 { > + compatible = "fixed-clock"; > + #clock-cells = <0>; > + /* This value must be overridden by boards that provide it. */ > + clock-frequency = <0>; > + status = "disabled"; > + }; > + > + audio_clk2: audio-clk2 { > + compatible = "fixed-clock"; > + #clock-cells = <0>; > + /* This value must be overridden by boards that provide it. */ > + clock-frequency = <0>; > + status = "disabled"; > + }; > + > cpus { > #address-cells = <1>; > #size-cells = <0>; > @@ -187,6 +203,86 @@ i2c3: i2c@10090c00 { > status = "disabled"; > }; > > + ssi0: ssi@100a8000 { > + compatible = "renesas,r9a08g045-ssi", > + "renesas,rz-ssi"; > + reg = <0 0x100a8000 0 0x400>; > + interrupts = <GIC_SPI 240 IRQ_TYPE_LEVEL_HIGH>, > + <GIC_SPI 241 IRQ_TYPE_EDGE_RISING>, > + <GIC_SPI 242 IRQ_TYPE_EDGE_RISING>; > + interrupt-names = "int_req", "dma_rx", "dma_tx"; > + clocks = <&cpg CPG_MOD R9A08G045_SSI0_PCLK2>, > + <&cpg CPG_MOD R9A08G045_SSI0_PCLK_SFR>, > + <&audio_clk1>, <&audio_clk2>; > + clock-names = "ssi", "ssi_sfr", "audio_clk1", "audio_clk2"; > + resets = <&cpg R9A08G045_SSI0_RST_M2_REG>; > + dmas = <&dmac 0x2665>, <&dmac 0x2666>; > + dma-names = "tx", "rx"; > + power-domains = <&cpg>; > + #sound-dai-cells = <0>; > + status = "disabled"; > + }; > + > + ssi1: ssi@100a8400 { > + compatible = "renesas,r9a08g045-ssi", > + "renesas,rz-ssi"; > + reg = <0 0x100a8400 0 0x400>; > + interrupts = <GIC_SPI 243 IRQ_TYPE_LEVEL_HIGH>, > + <GIC_SPI 244 IRQ_TYPE_EDGE_RISING>, > + <GIC_SPI 245 IRQ_TYPE_EDGE_RISING>; > + interrupt-names = "int_req", "dma_rx", "dma_tx"; > + clocks = <&cpg CPG_MOD R9A08G045_SSI1_PCLK2>, > + <&cpg CPG_MOD R9A08G045_SSI1_PCLK_SFR>, > + <&audio_clk1>, <&audio_clk2>; > + clock-names = "ssi", "ssi_sfr", "audio_clk1", "audio_clk2"; > + resets = <&cpg R9A08G045_SSI1_RST_M2_REG>; > + dmas = <&dmac 0x2669>, <&dmac 0x266a>; > + dma-names = "tx", "rx"; > + power-domains = <&cpg>; > + #sound-dai-cells = <0>; > + status = "disabled"; > + }; > + > + ssi2: ssi@100a8800 { > + compatible = "renesas,r9a08g045-ssi", > + "renesas,rz-ssi"; > + reg = <0 0x100a8800 0 0x400>; > + interrupts = <GIC_SPI 246 IRQ_TYPE_LEVEL_HIGH>, > + <GIC_SPI 247 IRQ_TYPE_EDGE_RISING>, > + <GIC_SPI 248 IRQ_TYPE_EDGE_RISING>; > + interrupt-names = "int_req", "dma_rx", "dma_tx"; > + clocks = <&cpg CPG_MOD R9A08G045_SSI2_PCLK2>, > + <&cpg CPG_MOD R9A08G045_SSI2_PCLK_SFR>, > + <&audio_clk1>, <&audio_clk2>; > + clock-names = "ssi", "ssi_sfr", "audio_clk1", "audio_clk2"; > + resets = <&cpg R9A08G045_SSI2_RST_M2_REG>; > + dmas = <&dmac 0x266d>, <&dmac 0x266e>; > + dma-names = "tx", "rx"; > + power-domains = <&cpg>; > + #sound-dai-cells = <0>; > + status = "disabled"; > + }; > + > + ssi3: ssi@100a8c00 { > + compatible = "renesas,r9a08g045-ssi", > + "renesas,rz-ssi"; > + reg = <0 0x100a8c00 0 0x400>; > + interrupts = <GIC_SPI 249 IRQ_TYPE_LEVEL_HIGH>, > + <GIC_SPI 250 IRQ_TYPE_EDGE_RISING>, > + <GIC_SPI 251 IRQ_TYPE_EDGE_RISING>; > + interrupt-names = "int_req", "dma_rx", "dma_tx"; > + clocks = <&cpg CPG_MOD R9A08G045_SSI3_PCLK2>, > + <&cpg CPG_MOD R9A08G045_SSI3_PCLK_SFR>, > + <&audio_clk1>, <&audio_clk2>; > + clock-names = "ssi", "ssi_sfr", "audio_clk1", "audio_clk2"; > + resets = <&cpg R9A08G045_SSI3_RST_M2_REG>; > + dmas = <&dmac 0x2671>, <&dmac 0x2672>; > + dma-names = "tx", "rx"; > + power-domains = <&cpg>; > + #sound-dai-cells = <0>; > + status = "disabled"; > + }; > + > cpg: clock-controller@11010000 { > compatible = "renesas,r9a08g045-cpg"; > reg = <0 0x11010000 0 0x10000>; > -- > 2.39.2
