* Qualcomm Atheros ath10k wireless devices Required properties: - compatible: Should be one of the following: * "qcom,ath10k" * "qcom,ipq4019-wifi" PCI based devices uses compatible string "qcom,ath10k" and takes calibration data along with board specific data via "qcom,ath10k-calibration-data". Rest of the properties are not applicable for PCI based devices. AHB based devices (i.e. ipq4019) uses compatible string "qcom,ipq4019-wifi" and also uses most of the properties defined in this doc (except "qcom,ath10k-calibration-data"). It uses "qcom,ath10k-pre-calibration-data" to carry pre calibration data. In general, entry "qcom,ath10k-pre-calibration-data" and "qcom,ath10k-calibration-data" conflict with each other and only one can be provided per device. Optional properties: - reg: Address and length of the register set for the device. - resets: Must contain an entry for each entry in reset-names. See ../reset/reseti.txt for details. - reset-names: Must include the list of following reset names, "wifi_cpu_init" "wifi_radio_srif" "wifi_radio_warm" "wifi_radio_cold" "wifi_core_warm" "wifi_core_cold" - clocks: List of clock specifiers, must contain an entry for each required entry in clock-names. - clock-names: Should contain the clock names "wifi_wcss_cmd", "wifi_wcss_ref", "wifi_wcss_rtc". - interrupts: List of interrupt lines. Must contain an entry for each entry in the interrupt-names property. - interrupt-names: Must include the entries for MSI interrupt names ("msi0" to "msi15") and legacy interrupt name ("legacy"), - qcom,msi_addr: MSI interrupt address. - qcom,msi_base: Base value to add before writing MSI data into MSI address register. - qcom,ath10k-calibration-variant: string to search for in the board-2.bin variant list with the same bus and device specific ids - qcom,ath10k-calibration-data : calibration data + board specific data as an array, the length can vary between hw versions. - qcom,ath10k-pre-calibration-data : pre calibration data as an array, the length can vary between hw versions. Example (to supply the calibration data alone): In this example, the node is defined as child node of the PCI controller. pci { pcie@0 { reg = <0 0 0 0 0>; #interrupt-cells = <1>; #size-cells = <2>; #address-cells = <3>; device_type = "pci"; ath10k@0,0 { reg = <0 0 0 0 0>; device_type = "pci"; qcom,ath10k-calibration-data = [ 01 02 03 ... ]; }; }; }; Example (to supply ipq4019 SoC wifi block details): wifi0: wifi@a000000 { compatible = "qcom,ipq4019-wifi"; reg = <0xa000000 0x200000>; resets = <&gcc WIFI0_CPU_INIT_RESET>, <&gcc WIFI0_RADIO_SRIF_RESET>, <&gcc WIFI0_RADIO_WARM_RESET>, <&gcc WIFI0_RADIO_COLD_RESET>, <&gcc WIFI0_CORE_WARM_RESET>, <&gcc WIFI0_CORE_COLD_RESET>; reset-names = "wifi_cpu_init", "wifi_radio_srif", "wifi_radio_warm", "wifi_radio_cold", "wifi_core_warm", "wifi_core_cold"; clocks = <&gcc GCC_WCSS2G_CLK>, <&gcc GCC_WCSS2G_REF_CLK>, <&gcc GCC_WCSS2G_RTC_CLK>; clock-names = "wifi_wcss_cmd", "wifi_wcss_ref", "wifi_wcss_rtc"; interrupts = <0 0x20 0x1>, <0 0x21 0x1>, <0 0x22 0x1>, <0 0x23 0x1>, <0 0x24 0x1>, <0 0x25 0x1>, <0 0x26 0x1>, <0 0x27 0x1>, <0 0x28 0x1>, <0 0x29 0x1>, <0 0x2a 0x1>, <0 0x2b 0x1>, <0 0x2c 0x1>, <0 0x2d 0x1>, <0 0x2e 0x1>, <0 0x2f 0x1>, <0 0xa8 0x0>; interrupt-names = "msi0", "msi1", "msi2", "msi3", "msi4", "msi5", "msi6", "msi7", "msi8", "msi9", "msi10", "msi11", "msi12", "msi13", "msi14", "msi15", "legacy"; qcom,msi_addr = <0x0b006040>; qcom,msi_base = <0x40>; qcom,ath10k-pre-calibration-data = [ 01 02 03 ... ]; };
