The C71x DSPs are 64 bit machine with fixed and floating point DSP operations. Similar to the R5F remote cores, the inter-processor communication between the main A72 cores and these DSP cores is achieved through shared memory and Mailboxes. The following firmware names are used by default for these DSP cores, and can be overridden in a board dts file if desired: MAIN C71_0 : j721s2-c71_0-fw MAIN C71_1 : j721s2-c71_1-fw Signed-off-by: Hari Nagalla Signed-off-by: Apurva Nandan --- arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi | 26 ++++++++++++++++++++++ 1 file changed, 26 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi b/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi index a8e23b5c6fd5..303e9f124b02 100644 --- a/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi @@ -1768,4 +1768,30 @@ main_r5fss1_core1: r5f@5f00000 { ti,loczrama = <1>; }; }; + + c71_0: dsp@64800000 { + compatible = "ti,j721s2-c71-dsp"; + reg = <0x00 0x64800000 0x00 0x00080000>, + <0x00 0x64e00000 0x00 0x0000c000>; + reg-names = "l2sram", "l1dram"; + ti,sci = <&sms>; + ti,sci-dev-id = <8>; + ti,sci-proc-ids = <0x30 0xff>; + resets = <&k3_reset 8 1>; + firmware-name = "j721s2-c71_0-fw"; + status = "disabled"; + }; + + c71_1: dsp@65800000 { + compatible = "ti,j721s2-c71-dsp"; + reg = <0x00 0x65800000 0x00 0x00080000>, + <0x00 0x65e00000 0x00 0x0000c000>; + reg-names = "l2sram", "l1dram"; + ti,sci = <&sms>; + ti,sci-dev-id = <11>; + ti,sci-proc-ids = <0x31 0xff>; + resets = <&k3_reset 11 1>; + firmware-name = "j721s2-c71_1-fw"; + status = "disabled"; + }; };
