1Texas Instruments' Message Manager Driver 2======================================== 3 4The Texas Instruments' Message Manager is a mailbox controller that has 5configurable queues selectable at SoC(System on Chip) integration. The Message 6manager is broken up into queues in different address regions that are called 7"proxies" - each instance is unidirectional and is instantiated at SoC 8integration 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 debug 17 region. 18- reg: Contains the register map per reg-names. 19- #mbox-cells Shall be 2. Contains the queue ID and proxy ID in that 20 order referring to the transfer path. 21- interrupt-names: Contains interrupt names matching the rx transfer path 22 for a given SoC. Receive interrupts shall be of the 23 format: "rx_<QID>". 24 For ti,k2g-message-manager, this shall contain: 25 "rx_005", "rx_057" 26- interrupts: Contains the interrupt information corresponding to 27 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 2 46 # TX queue ID is 0, proxy ID is 0 47 mboxes= <&msgmgr 5 2>, 48 <&msgmgr 0 0>; 49 [...] 50 }; 51
