This is just > compile-time tested. INTx is not supported by the driver as explained at: https://lore.kernel.org/r/be3e3c5f-0d48-41b0-87f4-2210f13b9460@ti.com/ The patch to fix the error displayed in the logs was posted at: https://lore.kernel.org/r/20240726135903.1255825-1-s-vadapalli@ti.com/ but wasn't accepted as-is. A different approach will be required to fix of_irq_parse_pci() instead as pointed out at: https://lore.kernel.org/r/20240729080006.GA8698@thinkpad/ [Trimmed] Regards, Siddharth.
