1Texas Instruments TCAN4x5x CAN Controller 2================================================ 3 4This file provides device node information for the TCAN4x5x interface contains. 5 6Required properties: 7 - compatible: "ti,tcan4x5x" 8 - reg: 0 9 - #address-cells: 1 10 - #size-cells: 0 11 - spi-max-frequency: Maximum frequency of the SPI bus the chip can 12 operate at should be less than or equal to 18 MHz. 13 - interrupt-parent: the phandle to the interrupt controller which provides 14 the interrupt. 15 - interrupts: interrupt specification for data-ready. 16 17See Documentation/devicetree/bindings/net/can/bosch,m_can.yaml for additional 18required property details. 19 20Optional properties: 21 - reset-gpios: Hardwired output GPIO. If not defined then software 22 reset. 23 - device-state-gpios: Input GPIO that indicates if the device is in 24 a sleep state or if the device is active. 25 - device-wake-gpios: Wake up GPIO to wake up the TCAN device. 26 27Example: 28tcan4x5x: tcan4x5x@0 { 29 compatible = "ti,tcan4x5x"; 30 reg = <0>; 31 #address-cells = <1>; 32 #size-cells = <1>; 33 spi-max-frequency = <10000000>; 34 bosch,mram-cfg = <0x0 0 0 16 0 0 1 1>; 35 interrupt-parent = <&gpio1>; 36 interrupts = <14 IRQ_TYPE_LEVEL_LOW>; 37 device-state-gpios = <&gpio3 21 GPIO_ACTIVE_HIGH>; 38 device-wake-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>; 39 reset-gpios = <&gpio1 27 GPIO_ACTIVE_HIGH>; 40}; 41
