From 41f5a0973259db9e4e3c9963d36505f80107d1a0 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 20 Nov 2023 17:16:06 +0100 Subject: USB: dwc3: qcom: fix wakeup after probe deferral The Qualcomm glue driver is overriding the interrupt trigger types defined by firmware when requesting the wakeup interrupts during probe. This can lead to a failure to map the DP/DM wakeup interrupts after a probe deferral as the firmware defined trigger types do not match the type used for the initial mapping: irq: type mismatch, failed to map hwirq-14 for interrupt-controller@b220000! irq: type mismatch, failed to map hwirq-15 for interrupt-controller@b220000! Fix this by not overriding the firmware provided trigger types when requesting the wakeup interrupts.
