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>;
|
||
|
|
};
