From 804a4cc7fe3cc7207b25c63f21ea82f1b77d19ae Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Tue, 25 Aug 2020 12:21:42 -0500 Subject: [PATCH] arm64: dts: ti: k3-j721e-main: Add C71x DSP node The J721E SoCs have a single TMS320C71x DSP Subsystem in the MAIN voltage domain containing the next-generation C711 CPU core. The subsystem has 32 KB of L1D configurable SRAM/Cache and 512 KB of L2 configurable SRAM/Cache. This subsystem has a CMMU but is not used currently. The inter-processor communication between the main A72 cores and the C711 processor is achieved through shared memory and a Mailbox. Add the DT node for this DSP processor sub-system in the common k3-j721e-main.dtsi file. The following firmware name is used by default for the C71x core, and can be overridden in a board dts file if desired: C71x_0 DSP: j7-c71_0-fw Signed-off-by: Suman Anna Signed-off-by: Nishanth Menon Reviewed-by: Lokesh Vutla Link: https://lore.kernel.org/r/20200825172145.13186-6-s-anna@ti.com --- arch/arm64/boot/dts/ti/k3-j721e-main.dtsi | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-j721e-main.dtsi b/arch/arm64/boot/dts/ti/k3-j721e-main.dtsi index 52f3373..00a36a14 100644 --- a/arch/arm64/boot/dts/ti/k3-j721e-main.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j721e-main.dtsi @@ -1375,4 +1375,16 @@ resets = <&k3_reset 143 1>; firmware-name = "j7-c66_1-fw"; }; + + c71_0: dsp@64800000 { + compatible = "ti,j721e-c71-dsp"; + reg = <0x00 0x64800000 0x00 0x00080000>, + <0x00 0x64e00000 0x00 0x0000c000>; + reg-names = "l2sram", "l1dram"; + ti,sci = <&dmsc>; + ti,sci-dev-id = <15>; + ti,sci-proc-ids = <0x30 0xff>; + resets = <&k3_reset 15 1>; + firmware-name = "j7-c71_0-fw"; + }; }; -- 2.7.4
