* [PATCH] dt-bindings: remoteproc: add Tightly Coupled Memory (TCM) bindings @ 2023-06-16 12:34 Radhey Shyam Pandey 2023-06-20 17:03 ` Rob Herring 0 siblings, 1 reply; 3+ messages in thread From: Radhey Shyam Pandey @ 2023-06-16 12:34 UTC (permalink / raw) To: andersson, mathieu.poirier, robh+dt, krzysztof.kozlowski+dt, conor+dt, michal.simek, ben.levinsky, tanmay.shah Cc: linux-remoteproc, devicetree, linux-arm-kernel, linux-kernel, git, Radhey Shyam Pandey Introduce bindings for TCM memory address space on AMD-xilinx Zynq UltraScale+ platform. As of now TCM addresses are hardcoded in xilinx remoteproc driver. This binding will help in defining TCM in device-tree and make it's access platform agnostic and data-driven from the driver. Tightly-coupled memories(TCMs) are low-latency memory that provides predictable instruction execution and predictable data load/store timing. Each Cortex-R5F processor contains two 64-bit wide 64 KB memory banks on the ATCM and BTCM ports, for a total of 128 KB of memory. In split mode, TCM resources(reg, ranges and power-domain) are documented in each R5 node and in lockstep mode TCM resources are documented in any of the R5 node. It also extends the examples for TCM split and lockstep modes. Signed-off-by: Radhey Shyam Pandey <radhey.shyam.pandey@amd.com> --- The inspiration for integrating TCM nodes in R5 nodes is taken from "5ee79c2ed5bd dt-bindings: remoteproc: Add bindings for R5F subsystem on TI K3 SoCs".Once the binding is reviewed/accepted will send out driver changes in follow-up series. --- .../remoteproc/xlnx,zynqmp-r5fss.yaml | 86 +++++++++++++++++-- 1 file changed, 81 insertions(+), 5 deletions(-) diff --git a/Documentation/devicetree/bindings/remoteproc/xlnx,zynqmp-r5fss.yaml b/Documentation/devicetree/bindings/remoteproc/xlnx,zynqmp-r5fss.yaml index 9f677367dd9f..0bc3a8bb8374 100644 --- a/Documentation/devicetree/bindings/remoteproc/xlnx,zynqmp-r5fss.yaml +++ b/Documentation/devicetree/bindings/remoteproc/xlnx,zynqmp-r5fss.yaml @@ -20,6 +20,12 @@ properties: compatible: const: xlnx,zynqmp-r5fss + "#address-cells": + const: 1 + + "#size-cells": + const: 1 + xlnx,cluster-mode: $ref: /schemas/types.yaml#/definitions/uint32 enum: [0, 1, 2] @@ -37,7 +43,7 @@ properties: 2: single cpu mode patternProperties: - "^r5f-[a-f0-9]+$": + "^r5f(.*)+$": type: object description: | The RPU is located in the Low Power Domain of the Processor Subsystem. @@ -54,8 +60,27 @@ patternProperties: compatible: const: xlnx,zynqmp-r5f + "#address-cells": + const: 1 + + "#size-cells": + const: 1 + + reg: + items: + - description: Address and Size of the ATCM internal memory region + - description: Address and Size of the BTCM internal memory region + + reg-names: + items: + - const: atcm + - const: btcm + + ranges: true + power-domains: - maxItems: 1 + minItems: 1 + maxItems: 3 mboxes: minItems: 1 @@ -112,13 +137,64 @@ additionalProperties: false examples: - | + #include <dt-bindings/power/xlnx-zynqmp-power.h> + + //Split mode configuration + remoteproc { + compatible = "xlnx,zynqmp-r5fss"; + xlnx,cluster-mode = <0>; + + #address-cells = <1>; + #size-cells = <1>; + r5f_0: r5f@ffe00000 { + compatible = "xlnx,zynqmp-r5f"; + #address-cells = <1>; + #size-cells = <1>; + reg = <0xffe00000 0x10000>, <0xffe20000 0x10000>; + reg-names = "atcm", "btcm"; + ranges = <0x0 0xffe00000 0x10000>, <0x20000 0xffe20000 0x10000>; + 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>, <&rpu0vdev0buffer>, <&rpu0vdev0vring0>, <&rpu0vdev0vring1>; + mboxes = <&ipi_mailbox_rpu0 0>, <&ipi_mailbox_rpu0 1>; + mbox-names = "tx", "rx"; + }; + + r5f_1: r5f@ffe90000 { + compatible = "xlnx,zynqmp-r5f"; + #address-cells = <1>; + #size-cells = <1>; + reg = <0xffe90000 0x10000>, <0xffeb0000 0x10000>; + reg-names = "atcm", "btcm"; + ranges = <0x0 0xffe90000 0x10000>, <0x20000 0xffeb0000 0x10000>; + 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>, <&rpu1vdev0buffer>, <&rpu1vdev0vring0>, <&rpu1vdev0vring1>; + mboxes = <&ipi_mailbox_rpu1 0>, <&ipi_mailbox_rpu1 1>; + mbox-names = "tx", "rx"; + }; + }; + + - | + //Lockstep configuration remoteproc { compatible = "xlnx,zynqmp-r5fss"; xlnx,cluster-mode = <1>; - r5f-0 { + #address-cells = <1>; + #size-cells = <1>; + r5f_00: r5f@ffe00000 { compatible = "xlnx,zynqmp-r5f"; - power-domains = <&zynqmp_firmware 0x7>; + #address-cells = <1>; + #size-cells = <1>; + reg = <0xffe00000 0x20000>, <0xffe20000 0x20000>; + reg-names = "atcm", "btcm"; + ranges = <0x0 0xffe00000 0x20000>, <0x20000 0xffe20000 0x20000>; + 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>, <&rpu0vdev0buffer>, <&rpu0vdev0vring0>, <&rpu0vdev0vring1>; mboxes = <&ipi_mailbox_rpu0 0>, <&ipi_mailbox_rpu0 1>; mbox-names = "tx", "rx"; @@ -126,7 +202,7 @@ examples: r5f-1 { compatible = "xlnx,zynqmp-r5f"; - power-domains = <&zynqmp_firmware 0x8>; + power-domains = <&zynqmp_firmware PD_RPU_1>; memory-region = <&rproc_1_fw_image>, <&rpu1vdev0buffer>, <&rpu1vdev0vring0>, <&rpu1vdev0vring1>; mboxes = <&ipi_mailbox_rpu1 0>, <&ipi_mailbox_rpu1 1>; mbox-names = "tx", "rx"; -- 2.25.1 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply related [flat|nested] 3+ messages in thread
