Hi, This is second iteration of the series. The previous version can be found from [1]. Currently drivers for ACPI enumerated devices that have their interrupt line connected to a GPIO controller instead of IO-APIC are required to do complete gpiod_get()/gpiod_to_irq() etc. dance themselves. This adds unnecessary lines of code to these drivers. It turned out that DT solved the problem already with introduction of of_irq_get() which is able to handle GPIO based interrupts as well through irqchip API [2]. The following three patches achieve the same for ACPI by introducing new function acpi_dev_gpio_irq_get() that is then used in I2C core to automatically translate ACPI GpioInt resource to Linux IRQ number. Changes to the previous version: - Added Rafael's ack to the first patch - Introduce new patch that makes I2C ACPI slave enumeration code use 0 to mean no interrupt. If no objections, I would like this to merged via either I2C or GPIO trees. Thanks.
