1Texas Instruments TCAN4x5x CAN Controller2================================================3 4This file provides device node information for the TCAN4x5x interface contains.5 6Required properties:7 - compatible:8 "ti,tcan4552", "ti,tcan4x5x"9 "ti,tcan4553", "ti,tcan4x5x" or10 "ti,tcan4x5x"11 - reg: 012 - #address-cells: 113 - #size-cells: 014 - spi-max-frequency: Maximum frequency of the SPI bus the chip can15 operate at should be less than or equal to 18 MHz.16 - interrupt-parent: the phandle to the interrupt controller which provides17 the interrupt.18 - interrupts: interrupt specification for data-ready.19 20See Documentation/devicetree/bindings/net/can/bosch,m_can.yaml for additional21required property details.22 23Optional properties:24 - reset-gpios: Hardwired output GPIO. If not defined then software25 reset.26 - device-state-gpios: Input GPIO that indicates if the device is in27 a sleep state or if the device is active. Not28 available with tcan4552/4553.29 - device-wake-gpios: Wake up GPIO to wake up the TCAN device. Not30 available with tcan4552/4553.31 - wakeup-source: Leave the chip running when suspended, and configure32 the RX interrupt to wake up the device.33 34Example:35tcan4x5x: tcan4x5x@0 {36 compatible = "ti,tcan4x5x";37 reg = <0>;38 #address-cells = <1>;39 #size-cells = <1>;40 spi-max-frequency = <10000000>;41 bosch,mram-cfg = <0x0 0 0 16 0 0 1 1>;42 interrupt-parent = <&gpio1>;43 interrupts = <14 IRQ_TYPE_LEVEL_LOW>;44 device-state-gpios = <&gpio3 21 GPIO_ACTIVE_HIGH>;45 device-wake-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;46 reset-gpios = <&gpio1 27 GPIO_ACTIVE_HIGH>;47 wakeup-source;48};49
