Hey Tarang Raval, let's continue discussing things on the mailing list. On 22.08.2024 06:42:49, Tarang Raval wrote: > Thank you for the feedback.

Can you point me to the upstream DTS? > Could you please help me understand the reasoning behind the > preference for level-triggered interrupts over edge-triggered ones If an edge interrupt occurs while the driver is in the ISR, it may lose this interrupt. The driver will not process the pending interrupt and CAN communication will get stuck. regards, Marc
Hi Marc, The CAN chip on the Kontron i.MX8M Mini Baseboard is the MCP2515, the same as ours, and they also use edge triggering. You can see the patch in the link below link : https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=8668d8b2e67fe7cf65f02becd5d67c0636689e82 Best regards, Tarang

Better, use a level triggered IRQ instead. regards, Mac
Hi alexander, Thank you for your feedback, Regarding your suggestion to switch to the USB connector node >> + extcon_usb: extcon-usbotg1 { >> + compatible = "linux,extcon-usb-gpio"; > >Please refer to Documentation/devicetree/bindings/extcon/extcon-usb-gpio.yaml: I couldn’t find the Documentation/devicetree/bindings/extcon/extcon-usb-gpio.yaml file as mentioned.

I referred to the following YAML file: link : https://www.kernel.org/doc/Documentation/devicetree/bindings/connector/usb-connector.yaml Could you please confirm if this is the correct file to refer to?

Instead, I located the extcon-usb-gpio.txt file, but it doesn’t contain documentation about connectors. Sorry, I thought my patch [1] was already applied. Meanwhile another one is applied instead [2].

Yeah, that's the one I'm referring to. Thanks Alexander
