The 15 Message manager is broken up into different address regions that are 16 called "threads" or "proxies" - each instance is unidirectional and is 17 instantiated at SoC integration level by system controller to indicate 18 receive or transmit path. 19 20properties: 21 $nodename: 22 pattern: "^mailbox@[0-9a-f]+$" 23 24 compatible: 25 const: ti,am654-secure-proxy 26 27 "#mbox-cells": 28 const: 1 29 description: 30 Contains the secure proxy thread ID used for the specific transfer path. 31 32 reg-names: 33 items: 34 - const: target_data 35 - const: rt 36 - const: scfg 37 38 reg: 39 minItems: 3 40 41 interrupt-names: 42 minItems: 1 43 maxItems: 100 44 items: 45 pattern: "^rx_[0-9]{3}$" 46 description: 47 Contains the interrupt name information for the Rx interrupt path for 48 secure proxy thread in the form 'rx_<PID>'. 49 50 interrupts: 51 minItems: 1 52 maxItems: 100 53 description: 54 Contains the interrupt information for the Rx interrupt path for secure 55 proxy. 56 57required: 58 - compatible 59 - reg-names 60 - reg 61 - interrupt-names 62 - interrupts 63 - "#mbox-cells" 64 65additionalProperties: false 66 67examples: 68 - | 69 #include <dt-bindings/interrupt-controller/arm-gic.h> 70 secure_proxy: mailbox@32c00000 { 71 compatible = "ti,am654-secure-proxy"; 72 #mbox-cells = <1>; 73 reg-names = "target_data", "rt", "scfg"; 74 reg = <0x32c00000 0x100000>, 75 <0x32400000 0x100000>, 76 <0x32800000 0x100000>; 77 interrupt-names = "rx_011"; 78 interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>; 79 }; 80
