MCP2515 overlay help needed

#1

I want to add CAN bus to Rock Pi 4, but I’m not familiar with device tree.
MCP2515 is a SPI to CAN module with open document.

#2

Which HAT are you using? Maybe we can add a device tree overlay for that.

#3

Tmall
eBay
These HATs are using same MCP2515 with little difference.

#4

Any update? I would also like an overlay for MCP2515

Go to linux/arch/arm/boot/dts and search for mcp2515 in *.dts or *.dtsi.
The results can be used as examples.
But be becareful with hardware difference like external clock input frequency for timing generation of MCP2515, SPI speed between MCP2515 and master, etc.
