I misunderstood your earlier response so I didn't clarify that portion of the commit message. Thanks for your patience. How does this updated commit message sound? If you think it's sufficiently clear, I can send a v3 for this patch. This patch allows headphone plug detect and mic present detect to be enabled at the same time. This patch implements an irq_chip with irq_domain directly instead of using regmap-irq, so that interrupt source line polarities can be flipped to support irq sharing. This patch does not add polarity flipping support within regmap-irq because there is extra work that must be done within the irq handler to support hotword detection. On the Chromebook Pixel, the firmware will disconnect GPIO1 from the jack detection irq when a hotword is detected and trigger the interrupt handler. Inside the handler, we will need to detect this, report the hotword event, and re-connect GPIO1 to the jack detection irq. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
