1 Texas Instruments TCAN4x5x CAN Controller
2 ================================================
3
4 This file provides device node information for the TCAN4x5x interface contains.
5
6 Required 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
20 See Documentation/devicetree/bindings/net/can/bosch,m_can.yaml for additional
21 required property details.
22
23 Optional 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.

34 Example:
35 tcan4x5x: 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;
