Link to discussion: https://lore.kernel.org/netdev/20210816115953.72533-7-andriy.shevchenko@linux.intel.com/T/ Patch 1 adds support to a GPIO IRQ handler in gpio-mlxbf2.c. Patch 2 is a follow up removal of custom GPIO IRQ handling from the mlxbf_gige driver and replacing it with a simple IRQ request. The ACPI table for the mlxbf_gige driver is responsible for instantiating the PHY GPIO interrupt via GpioInt. Andy Shevchenko, could you please review this patch series. David Miller, could you please ack the changes in the mlxbf_gige driver. v5 vs. v4 patch: - Remove a fix which check if bgpio_init has failed. This fix should in a separate patch targeting the stable branch.
