1*4882a593Smuzhiyun* Microchip MCP251X stand-alone CAN controller device tree bindings
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun - compatible: Should be one of the following:
5*4882a593Smuzhiyun   - "microchip,mcp2510" for MCP2510.
6*4882a593Smuzhiyun   - "microchip,mcp2515" for MCP2515.
7*4882a593Smuzhiyun   - "microchip,mcp25625" for MCP25625.
8*4882a593Smuzhiyun - reg: SPI chip select.
9*4882a593Smuzhiyun - clocks: The clock feeding the CAN controller.
10*4882a593Smuzhiyun - interrupts: Should contain IRQ line for the CAN controller.
11*4882a593Smuzhiyun
12*4882a593SmuzhiyunOptional properties:
13*4882a593Smuzhiyun - vdd-supply: Regulator that powers the CAN controller.
14*4882a593Smuzhiyun - xceiver-supply: Regulator that powers the CAN transceiver.
15*4882a593Smuzhiyun - gpio-controller: Indicates this device is a GPIO controller.
16*4882a593Smuzhiyun - #gpio-cells: Should be two. The first cell is the pin number and
17*4882a593Smuzhiyun                the second cell is used to specify the gpio polarity.
