These subsystems do not have an MMU but contain a Region Address Translator (RAT) sub-module for translating 32-bit processor addresses into larger bus addresses. The inter-processor communication between the main A72 cores and these processors is achieved through shared memory and Mailboxes. Add the DT nodes for these DSP processor sub-systems in the common k3-j721e-main.dtsi file. The following firmware names are used by default for these cores, and can be overridden in a board dts file if desired: C66x_0 DSP: j7-c66_0-fw C66x_1 DSP: j7-c66_1-fw Signed-off-by: Suman Anna --- v2: No changes v1: https://patchwork.kernel.org/patch/11725349/ arch/arm64/boot/dts/ti/k3-j721e-main.dtsi | 26 +++++++++++++++++++++++ 1 file changed, 26 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-j721e-main.dtsi b/arch/arm64/boot/dts/ti/k3-j721e-main.dtsi index 12ceea9b3c9a..46cde2677e17 100644 --- a/arch/arm64/boot/dts/ti/k3-j721e-main.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j721e-main.dtsi @@ -1326,4 +1326,30 @@ watchdog1: watchdog@2210000 { assigned-clocks = <&k3_clks 253 1>; assigned-clock-parents = <&k3_clks 253 5>; }; + + c66_0: dsp@4d80800000 { + compatible = "ti,j721e-c66-dsp"; + reg = <0x4d 0x80800000 0x00 0x00048000>, + <0x4d 0x80e00000 0x00 0x00008000>, + <0x4d 0x80f00000 0x00 0x00008000>; + reg-names = "l2sram", "l1pram", "l1dram"; + ti,sci = <&dmsc>; + ti,sci-dev-id = <142>; + ti,sci-proc-ids = <0x03 0xff>; + resets = <&k3_reset 142 1>; + firmware-name = "j7-c66_0-fw"; + }; + + c66_1: dsp@4d81800000 { + compatible = "ti,j721e-c66-dsp"; + reg = <0x4d 0x81800000 0x00 0x00048000>, + <0x4d 0x81e00000 0x00 0x00008000>, + <0x4d 0x81f00000 0x00 0x00008000>; + reg-names = "l2sram", "l1pram", "l1dram"; + ti,sci = <&dmsc>; + ti,sci-dev-id = <143>; + ti,sci-proc-ids = <0x04 0xff>; + resets = <&k3_reset 143 1>; + firmware-name = "j7-c66_1-fw"; + }; }; -- 2.28.0
