1Texas Instruments TCAN4x5x CAN Controller 2================================================ 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" or 10 "ti,tcan4x5x" 11 - reg: 0 12 - #address-cells: 1 13 - #size-cells: 0 14 - spi-max-frequency: Maximum frequency of the SPI bus the chip can 15 operate at should be less than or equal to 18 MHz. 16 - interrupt-parent: the phandle to the interrupt controller which provides 17 the interrupt. 18 - interrupts: interrupt specification for data-ready. 19 20See Documentation/devicetree/bindings/net/can/bosch,m_can.yaml for additional 21required property details. 22 23Optional properties: 24 - reset-gpios: Hardwired output GPIO. If not defined then software 25 reset. 26 - device-state-gpios: Input GPIO that indicates if the device is in 27 a sleep state or if the device is active. Not 28 available with tcan4552/4553. 29 - device-wake-gpios: Wake up GPIO to wake up the TCAN device. Not 30 available with tcan4552/4553. 31 - wakeup-source: Leave the chip running when suspended, and configure 32 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
