| Texas Instruments TCAN4x5x CAN Controller |
| ================================================ |
| |
| This file provides device node information for the TCAN4x5x interface contains. |
| |
| Required properties: |
| - compatible: "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. |
| - device-wake-gpios: Wake up GPIO to wake up the TCAN 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>; |
| }; |
