Tool/software: Linux
Hi,
we used the SPI extended GPIO function of the MCP23S17 base on Linux in our project, and the Linux version is 4.14.
I configured DTS according to the file ‘/Documentation/devicetree/bindings/gpio/gpio-mcp23s08.txt‘’.
Our requirement is to configure all IOs as interrupt inputs, INTA and INTB as interrupt outputs. I checked the chip driver and could not found the DTS node to configure this feature.
Does the driver not support configuring the above function from DTS?
Best Regards!
