CBB 1.0 has multiple hierarchical sub-NOCs (Network-on-Chip) and + connects various initiators and targets using different bridges like AXIP2P, AXI2APB. + + This driver handles errors due to illegal register accesses reported by the NOCs inside the CBB. + NOCs reporting errors are cluster NOCs "AON-NOC, SCE-NOC, RCE-NOC, BPMP-NOC, CV-NOC" and "CBB + Central NOC" which is the main NOC. + + By default, the access issuing initiator is informed about the error using SError or Data Abort + exception unless the ERD (Error Response Disable) is enabled/set for that initiator. If the ERD + is enabled, then SError or Data Abort is masked and the error is reported with interrupt. + + - For CCPLEX (CPU Complex) initiator, the driver sets ERD bit. So, the errors due to illegal + accesses from CCPLEX are reported by interrupts. If ERD is not set, then error is reported by + SError. + - For other initiators, the ERD is disabled. So, the access issuing initiator is informed about + the illegal access by Data Abort exception. In addition, an interrupt is also generated to + CCPLEX. These initiators include all engines using Cortex-R5 (which is ARMv7 CPU cluster) and + engines like TSEC (Security co-processor), NVDEC (NVIDIA Video Decoder engine) etc which can + initiate transactions. + + The driver prints relevant debug information like Error Code, Error Description, Master, Address, + AXI ID, Cache, Protection, Security Group etc on receiving error notification. + +properties: + $nodename: + pattern: "^[a-z]+-noc@[0-9a-f]+$" + + compatible: + enum: + - nvidia,tegra194-cbb-noc + - nvidia,tegra194-aon-noc + - nvidia,tegra194-bpmp-noc + - nvidia,tegra194-rce-noc + - nvidia,tegra194-sce-noc + + reg: + maxItems: 1 + + interrupts: + description: + CCPLEX receives secure or nonsecure interrupt depending on error type.

The Tegra234 SoC has different fabrics based on CBB2.0 architecture which + include cluster fabrics BPMP, AON, PSC, SCE, RCE, DCE, FSI and "CBB central fabric". + + In CBB 2.0, each initiator which can issue transactions connects to a Root Master Node (MN) + before it connects to any other element of the fabric. Each Root MN contains a Error Monitor + (EM) which detects and logs error. Interrupts from various EM blocks are collated by Error + Notifier (EN) which is per fabric and presents a single interrupt from fabric to the SoC + interrupt controller. + + The driver handles errors from CBB due to illegal register accesses and prints debug information + about failed transaction on receiving the interrupt from EN. Debug information includes Error + Code, Error Description, MasterID, Fabric, SlaveID, Address, Cache, Protection, Security Group + etc on receiving error notification. + + If the Error Response Disable (ERD) is set/enabled for an initiator, then SError or Data abort + exception error response is masked and an interrupt is used for reporting errors due to illegal + accesses from that initiator. The value returned on read failures is '0xFFFFFFFF' for + compatibility with PCIE. + +properties: + $nodename: + pattern: "^[a-z]+-fabric@[0-9a-f]+$" + + compatible: + enum: + - nvidia,tegra234-aon-fabric + - nvidia,tegra234-bpmp-fabric + - nvidia,tegra234-cbb-fabric + - nvidia,tegra234-dce-fabric + - nvidia,tegra234-rce-fabric + - nvidia,tegra234-sce-fabric + + reg: + maxItems: 1 + + interrupts: + items: + - description: secure interrupt from error notifier + +additionalProperties: true + +required: + - compatible + - reg + - interrupts + +examples: + - | + #include + + cbb-fabric@1300000 { + compatible = "nvidia,tegra234-cbb-fabric"; + reg = <0x13a00000 0x400000>; + interrupts = ; + status = "okay"; + };
