Please refer GENI based QUP wrapper controller node bindings 24 described in Documentation/devicetree/bindings/soc/qcom/qcom,geni-se.yaml. 25 26allOf: 27 - $ref: /schemas/spi/spi-controller.yaml# 28 29properties: 30 compatible: 31 const: qcom,geni-spi 32 33 clocks: 34 maxItems: 1 35 36 clock-names: 37 const: se 38 39 dmas: 40 maxItems: 2 41 42 dma-names: 43 items: 44 - const: tx 45 - const: rx 46 47 interconnects: 48 maxItems: 2 49 50 interconnect-names: 51 items: 52 - const: qup-core 53 - const: qup-config 54 55 interrupts: 56 maxItems: 1 57 58 operating-points-v2: true 59 60 power-domains: 61 maxItems: 1 62 63 reg: 64 maxItems: 1 65 66required: 67 - compatible 68 - clocks 69 - clock-names 70 - interrupts 71 - reg 72 73unevaluatedProperties: false 74 75examples: 76 - | 77 #include <dt-bindings/clock/qcom,gcc-sc7180.h> 78 #include <dt-bindings/interconnect/qcom,sc7180.h> 79 #include <dt-bindings/interrupt-controller/arm-gic.h> 80 #include <dt-bindings/power/qcom-rpmpd.h> 81 82 spi@880000 { 83 compatible = "qcom,geni-spi"; 84 reg = <0x00880000 0x4000>; 85 clock-names = "se"; 86 clocks = <&gcc GCC_QUPV3_WRAP0_S0_CLK>; 87 pinctrl-names = "default"; 88 pinctrl-0 = <&qup_spi0_default>; 89 interrupts = <GIC_SPI 601 IRQ_TYPE_LEVEL_HIGH>; 90 #address-cells = <1>; 91 #size-cells = <0>; 92 power-domains = <&rpmhpd SC7180_CX>; 93 operating-points-v2 = <&qup_opp_table>; 94 interconnects = <&qup_virt MASTER_QUP_CORE_0 0 &qup_virt SLAVE_QUP_CORE_0 0>, 95 <&gem_noc MASTER_APPSS_PROC 0 &config_noc SLAVE_QUP_0 0>; 96 interconnect-names = "qup-core", "qup-config"; 97 }; 98 99 - | 100 #include <dt-bindings/dma/qcom-gpi.h> 101 102 spi@884000 { 103 compatible = "qcom,geni-spi"; 104 reg = <0x00884000 0x4000>; 105 clock-names = "se"; 106 clocks = <&gcc GCC_QUPV3_WRAP0_S1_CLK>; 107 dmas = <&gpi_dma0 0 1 QCOM_GPI_SPI>, 108 <&gpi_dma0 1 1 QCOM_GPI_SPI>; 109 dma-names = "tx", "rx"; 110 pinctrl-names = "default"; 111 pinctrl-0 = <&qup_spi1_default>; 112 interrupts = <GIC_SPI 602 IRQ_TYPE_LEVEL_HIGH>; 113 #address-cells = <1>; 114 #size-cells = <0>; 115 };
