This patch also adds alternative remoteproc node to represent remoteproc cluster in split mode. By default lockstep mode is enabled and users should disable it before using split mode dts. Both device-tree nodes can't be used simultaneously one of them must be disabled. For zcu102-1.0 and zcu102-1.1 board remoteproc split mode dts node is enabled and lockstep mode dts is disabled. Signed-off-by: Tanmay Shah --- Changes in v6: - Introduce new node entry for r5f cluster split mode dts and keep it disabled by default. - Keep remoteproc lockstep mode enabled by default to maintian back compatibility. - Enable split mode only for zcu102 board to demo split mode use .../boot/dts/xilinx/zynqmp-zcu102-rev1.0.dts | 8 +++ arch/arm64/boot/dts/xilinx/zynqmp.dtsi | 60 +++++++++++++++++-- 2 files changed, 63 insertions(+), 5 deletions(-) diff --git a/arch/arm64/boot/dts/xilinx/zynqmp-zcu102-rev1.0.dts b/arch/arm64/boot/dts/xilinx/zynqmp-zcu102-rev1.0.dts index c8f71a1aec89..495ca94b45db 100644 --- a/arch/arm64/boot/dts/xilinx/zynqmp-zcu102-rev1.0.dts +++ b/arch/arm64/boot/dts/xilinx/zynqmp-zcu102-rev1.0.dts @@ -14,6 +14,14 @@ / { compatible = "xlnx,zynqmp-zcu102-rev1.0", "xlnx,zynqmp-zcu102", "xlnx,zynqmp"; }; +&rproc_split { + status = "okay"; +}; + +&rproc_lockstep { + status = "disabled"; +}; + &eeprom { #address-cells = <1>; #size-cells = <1>; diff --git a/arch/arm64/boot/dts/xilinx/zynqmp.dtsi b/arch/arm64/boot/dts/xilinx/zynqmp.dtsi index b61fc99cd911..602e6aba7ac5 100644 --- a/arch/arm64/boot/dts/xilinx/zynqmp.dtsi +++ b/arch/arm64/boot/dts/xilinx/zynqmp.dtsi @@ -247,19 +247,69 @@ fpga_full: fpga-full { ranges; }; - remoteproc { + rproc_lockstep: remoteproc@ffe00000 { compatible = "xlnx,zynqmp-r5fss"; xlnx,cluster-mode = <1>; - r5f-0 { + #address-cells = <2>; + #size-cells = <2>; + + ranges = <0x0 0x0 0x0 0xffe00000 0x0 0x20000>, + <0x0 0x20000 0x0 0xffe20000 0x0 0x20000>, + <0x1 0x0 0x0 0xffe90000 0x0 0x10000>, + <0x1 0x20000 0x0 0xffeb0000 0x0 0x10000>; + + r5f@0 { + compatible = "xlnx,zynqmp-r5f"; + reg = <0x0 0x0 0x0 0x20000>, <0x0 0x20000 0x0 0x20000>; + reg-names = "atcm", "btcm"; + power-domains = <&zynqmp_firmware PD_RPU_0>, + <&zynqmp_firmware PD_R5_0_ATCM>, + <&zynqmp_firmware PD_R5_0_BTCM>; + memory-region = <&rproc_0_fw_image>; + }; + + r5f@1 { + compatible = "xlnx,zynqmp-r5f"; + reg = <0x1 0x0 0x0 0x10000>, <0x1 0x20000 0x0 0x10000>; + reg-names = "atcm", "btcm"; + power-domains = <&zynqmp_firmware PD_RPU_1>, + <&zynqmp_firmware PD_R5_1_ATCM>, + <&zynqmp_firmware PD_R5_1_BTCM>; + memory-region = <&rproc_1_fw_image>; + }; + }; + + rproc_split: remoteproc-split@ffe00000 { + status = "disabled"; + compatible = "xlnx,zynqmp-r5fss"; + xlnx,cluster-mode = <0>; + + #address-cells = <2>; + #size-cells = <2>; + + ranges = <0x0 0x0 0x0 0xffe00000 0x0 0x10000>, + <0x0 0x20000 0x0 0xffe20000 0x0 0x10000>, + <0x1 0x0 0x0 0xffe90000 0x0 0x10000>, + <0x1 0x20000 0x0 0xffeb0000 0x0 0x10000>; + + r5f@0 { compatible = "xlnx,zynqmp-r5f"; - power-domains = <&zynqmp_firmware PD_RPU_0>; + reg = <0x0 0x0 0x0 0x10000>, <0x0 0x20000 0x0 0x10000>; + reg-names = "atcm", "btcm"; + power-domains = <&zynqmp_firmware PD_RPU_0>, + <&zynqmp_firmware PD_R5_0_ATCM>, + <&zynqmp_firmware PD_R5_0_BTCM>; memory-region = <&rproc_0_fw_image>; }; - r5f-1 { + r5f@1 { compatible = "xlnx,zynqmp-r5f"; - power-domains = <&zynqmp_firmware PD_RPU_1>; + reg = <0x1 0x0 0x0 0x10000>, <0x1 0x20000 0x0 0x10000>; + reg-names = "atcm", "btcm"; + power-domains = <&zynqmp_firmware PD_RPU_1>, + <&zynqmp_firmware PD_R5_1_ATCM>, + <&zynqmp_firmware PD_R5_1_BTCM>; memory-region = <&rproc_1_fw_image>; }; };
