| # Common fields for CAN controllers |

| include: base.yaml |
| |
| properties: |
| bus-speed: |
| type: int |
| required: true |
| description: | |
| Initial bitrate in bit/s. |
| sample-point: |
| type: int |
| description: | |
| Initial sample point in per mille (e.g. 875 equals 87.5%). |
| |
| This property is required unless the timing is specified using time quanta based properties |
| (`sjw`, `prop-seg`, `phase-seg1`, and `phase-seg2`). |
| |
| If this property is present, the time quanta based timing properties are ignored. |
| sjw: |
| type: int |
| deprecated: true |
| default: 1 |
| description: | |
| Initial time quanta of resynchronization jump width (ISO 11898-1). |
| |
| Deprecated in favor of automatic calculation of a suitable default SJW based on existing |
| timing parameters. Default of 1 matches the default value previously used for all in-tree CAN |
| controller devicetree instances. |
| |
| Applications can still manually set the SJW using the CAN timing APIs. |
| prop-seg: |
| type: int |
| deprecated: true |
| description: | |
| Initial time quanta of propagation segment (ISO 11898-1). Deprecated in favor of setting |
| advanced timing parameters from the application. |
| phase-seg1: |
| type: int |
| deprecated: true |
| description: | |
| Initial time quanta of phase buffer 1 segment (ISO 11898-1). Deprecated in favor of setting |
| advanced timing parameters from the application. |
| phase-seg2: |
| type: int |
| deprecated: true |
| description: | |
| Initial time quanta of phase buffer 2 segment (ISO 11898-1). Deprecated in favor of setting |
| advanced timing parameters from the application. |
| phys: |
| type: phandle |
| description: | |
| Actively controlled CAN transceiver. |
| |
| Example: |
| transceiver0: can-phy0 { |
| compatible = "nxp,tja1040", "can-transceiver-gpio"; |
| standby-gpios = <gpioa 0 GPIO_ACTIVE_HIGH>; |
| max-bitrate = <1000000>; |
| #phy-cells = <0>; |
| }; |
| |
| &can0 { |
| status = "okay"; |
| |
| phys = <&transceiver0>; |
| }; |
| |
| child-binding: |
| description: | |
| Passive CAN transceiver. The child node must be named "can-transceiver". |
| |
| Example: |
| &can0 { |
| status = "okay"; |
| |
| can-transceiver { |
| max-bitrate = <1000000>; |
| }; |
| }; |
| |
| properties: |
| max-bitrate: |
| type: int |
| required: true |
| description: | |
| The maximum bitrate supported by the CAN transceiver in bits/s. |
