An SoC may have multiple FlexRM -hardware blocks. There is one device tree entry per FlexRM block. The -FlexRM driver will create a mailbox-controller instance for given FlexRM -hardware block where each mailbox channel is a separate FlexRM ring. - -Required properties: --------------------- -- compatible: Should be "brcm,iproc-flexrm-mbox" -- reg: Specifies base physical address and size of the FlexRM - ring registers -- msi-parent: Phandles (and potential Device IDs) to MSI controllers - The FlexRM engine will send MSIs (instead of wired - interrupts) to CPU. There is one MSI for each FlexRM ring. - Refer devicetree/bindings/interrupt-controller/msi.txt -- #mbox-cells: Specifies the number of cells needed to encode a mailbox - channel. This should be 3. - - The 1st cell is the mailbox channel number. - - The 2nd cell contains MSI completion threshold. This is the - number of completion messages for which FlexRM will inject - one MSI interrupt to CPU. - - The 3rd cell contains MSI timer value representing time for - which FlexRM will wait to accumulate N completion messages - where N is the value specified by 2nd cell above. If FlexRM - does not get required number of completion messages in time - specified by this cell then it will inject one MSI interrupt - to CPU provided at least one completion message is available. - -Optional properties: --------------------- -- dma-coherent: Present if DMA operations made by the FlexRM engine (such - as DMA descriptor access, access to buffers pointed by DMA - descriptors and read/write pointer updates to DDR) are - cache coherent with the CPU. - -Example: --------- -crypto_mbox: mbox@67000000 { - compatible = "brcm,iproc-flexrm-mbox"; - reg = <0x67000000 0x200000>; - msi-parent = <&gic_its 0x7f00>; - #mbox-cells = <3>; -}; - -crypto@672c0000 { - compatible = "brcm,spu2-v2-crypto"; - reg = <0x672c0000 0x1000>; - mboxes = <&crypto_mbox 0 0x1 0xffff>, - <&crypto_mbox 1 0x1 0xffff>, - <&crypto_mbox 16 0x1 0xffff>, - <&crypto_mbox 17 0x1 0xffff>, - <&crypto_mbox 30 0x1 0xffff>, - <&crypto_mbox 31 0x1 0xffff>; -};

Applied, thanks!
