Texas Instruments TCAN4x5x CAN Controller ================================================ This file provides device node information for the TCAN4x5x interface contains. Required properties: - compatible: "ti,tcan4552", "ti,tcan4x5x" "ti,tcan4553", "ti,tcan4x5x" or "ti,tcan4x5x" - reg: 0 - #address-cells: 1 - #size-cells: 0 - spi-max-frequency: Maximum frequency of the SPI bus the chip can operate at should be less than or equal to 18 MHz. - interrupt-parent: the phandle to the interrupt controller which provides the interrupt. - interrupts: interrupt specification for data-ready. See Documentation/devicetree/bindings/net/can/bosch,m_can.yaml for additional required property details. Optional properties: - reset-gpios: Hardwired output GPIO. If not defined then software reset. - device-state-gpios: Input GPIO that indicates if the device is in a sleep state or if the device is active. Not available with tcan4552/4553. - device-wake-gpios: Wake up GPIO to wake up the TCAN device. Not available with tcan4552/4553. - wakeup-source: Leave the chip running when suspended, and configure the RX interrupt to wake up the device. Example: tcan4x5x: tcan4x5x@0 { compatible = "ti,tcan4x5x"; reg = <0>; #address-cells = <1>; #size-cells = <1>; spi-max-frequency = <10000000>; bosch,mram-cfg = <0x0 0 0 16 0 0 1 1>; interrupt-parent = <&gpio1>; interrupts = <14 IRQ_TYPE_LEVEL_LOW>; device-state-gpios = <&gpio3 21 GPIO_ACTIVE_HIGH>; device-wake-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>; reset-gpios = <&gpio1 27 GPIO_ACTIVE_HIGH>; wakeup-source; };
