| Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame] | 1 | * Microchip MCP251X stand-alone CAN controller device tree bindings |
| 2 | |
| 3 | Required properties: |
| 4 | - compatible: Should be one of the following: |
| 5 | - "microchip,mcp2510" for MCP2510. |
| 6 | - "microchip,mcp2515" for MCP2515. |
| 7 | - "microchip,mcp25625" for MCP25625. |
| 8 | - reg: SPI chip select. |
| 9 | - clocks: The clock feeding the CAN controller. |
| 10 | - interrupts: Should contain IRQ line for the CAN controller. |
| 11 | |
| 12 | Optional properties: |
| 13 | - vdd-supply: Regulator that powers the CAN controller. |
| 14 | - xceiver-supply: Regulator that powers the CAN transceiver. |
| 15 | - gpio-controller: Indicates this device is a GPIO controller. |
| 16 | - #gpio-cells: Should be two. The first cell is the pin number and |
| 17 | the second cell is used to specify the gpio polarity. |
| 18 | |
| 19 | Example: |
| 20 | can0: can@1 { |
| 21 | compatible = "microchip,mcp2515"; |
| 22 | reg = <1>; |
| 23 | clocks = <&clk24m>; |
| 24 | interrupt-parent = <&gpio4>; |
| 25 | interrupts = <13 IRQ_TYPE_LEVEL_LOW>; |
| 26 | vdd-supply = <®5v0>; |
| 27 | xceiver-supply = <®5v0>; |
| 28 | gpio-controller; |
| 29 | #gpio-cells = <2>; |
| 30 | }; |
