1Texas Instruments' Message Manager Driver2========================================3 4The Texas Instruments' Message Manager is a mailbox controller that has5configurable queues selectable at SoC(System on Chip) integration. The Message6manager is broken up into queues in different address regions that are called7"proxies" - each instance is unidirectional and is instantiated at SoC8integration level to indicate receive or transmit path.9 10Message Manager Device Node:11===========================12Required properties:13--------------------14- compatible: Shall be: "ti,k2g-message-manager"15- reg-names queue_proxy_region - Map the queue proxy region.16 queue_state_debug_region - Map the queue state debug17 region.18- reg: Contains the register map per reg-names.19- #mbox-cells Shall be 2. Contains the queue ID and proxy ID in that20 order referring to the transfer path.21- interrupt-names: Contains interrupt names matching the rx transfer path22 for a given SoC. Receive interrupts shall be of the23 format: "rx_<QID>".24 For ti,k2g-message-manager, this shall contain:25 "rx_005", "rx_057"26- interrupts: Contains the interrupt information corresponding to27 interrupt-names property.28 29Example(K2G):30------------31 32 msgmgr: msgmgr@2a00000 {33 compatible = "ti,k2g-message-manager";34 #mbox-cells = <2>;35 reg-names = "queue_proxy_region", "queue_state_debug_region";36 reg = <0x02a00000 0x400000>, <0x028c3400 0x400>;37 interrupt-names = "rx_005", "rx_057";38 interrupts = <GIC_SPI 324 IRQ_TYPE_LEVEL_HIGH>,39 <GIC_SPI 327 IRQ_TYPE_LEVEL_HIGH>;40 };41 42 pmmc: pmmc {43 [...]44 mbox-names = "rx", "tx";45 # RX queue ID is 5, proxy ID is 246 # TX queue ID is 0, proxy ID is 047 mboxes= <&msgmgr 5 2>,48 <&msgmgr 0 0>;49 [...]50 };51
