> The BlueField GPIO HW only support Edge interrupts. O.K. So please remove all level support from this driver, and return -EINVAL if requested to do level. This also means, you cannot use interrupts with the Ethernet PHY. The PHY is using level interrupts. Why not? The HW folks said it is alright because they Do some internal conversion of PHY signal and we have tested This extensively.
