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 32 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>;
};
