[PATCH v2] usb: chipidea: ci_hdrc_imx: use "wakeup" suffix for wakeup interrupt name
From: Xu Yang
Date: Mon Jan 12 2026 - 06:02:47 EST
Currently the wakeup and controller interrupt name are same. It's not
easy to find the correct one in /proc/interrupt at the first glance.
Rename the wakeup interrupt name for better distinction.
