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. v3 vs. v2 patch: - Add IRQ_TYPE_LEVEL* back to mlxbf2_gpio_irq_set_type. YU_GPIO_CAUSE_FALL_EN and YU_GPIO_CAUSE_RISE_EN are configured in Both level and edge interrupts cases.
