Each sub-node must contain: - memory-region: Usage: required Value type: Definition: reference to the reserved-memory for the region The Hexagon node may also have an subnode named either "smd-edge" or "glink-edge" that describes the communication edge, channels and devices related to the Hexagon. See ../soc/qcom/qcom,smd.txt and ../soc/qcom/qcom,glink.txt for details on how to describe these. = EXAMPLE The following example describes the resources needed to boot control the Hexagon, as it is found on MSM8974 boards. modem-rproc@fc880000 { compatible = "qcom,q6v5-pil"; reg = <0xfc880000 0x100>, <0xfc820000 0x020>; reg-names = "qdsp6", "rmb"; interrupts-extended = <&intc 0 24 1>, <&modem_smp2p_in 0 0>, <&modem_smp2p_in 1 0>, <&modem_smp2p_in 2 0>, <&modem_smp2p_in 3 0>; interrupt-names = "wdog", "fatal", "ready", "handover", "stop-ack"; clocks = <&gcc GCC_MSS_Q6_BIMC_AXI_CLK>, <&gcc GCC_MSS_CFG_AHB_CLK>, <&gcc GCC_BOOT_ROM_AHB_CLK>; clock-names = "iface", "bus", "mem"; qcom,halt-regs = <&tcsr_mutex_block 0x1180 0x1200 0x1280>; resets = <&gcc GCC_MSS_RESTART>; reset-names = "mss_restart"; cx-supply = <&pm8841_s2>; mss-supply = <&pm8841_s3>; mx-supply = <&pm8841_s1>; pll-supply = <&pm8941_l12>; qcom,smem-states = <&modem_smp2p_out 0>; qcom,smem-state-names = "stop"; mba { memory-region = <&mba_region>; }; mpss { memory-region = <&mpss_region>; }; };
