From 5dd588f49b85e0a727adee125d1a61e7f6012617 Mon Sep 17 00:00:00 2001 From: Coia Prant Date: Fri, 3 Jul 2026 04:24:29 +0800 Subject: [PATCH] arm64: dts: rockchip: Fix incorrect interrupt for the 9Tripod X3568 v4 The recently changes for 9Tripod X3568 mistakenly configured the WiFi host-wake interrupt trigger type as IRQ_TYPE_LEVEL_LOW. However, the associated pin `wifi_host_wake_irq` is configured with an internal pull-down resistor. When the WiFi module enters a low-power sleep state and leaves the pin floating, this pull-down bias drives the pin low. Since the interrupt is incorrectly set to level-low, this combination traps the kernel in an endless interrupt loop. Correct the interrupt trigger type to IRQ_TYPE_LEVEL_HIGH based on the actual hardware logic: the pin is kept low by default and driven high by the WiFi module to wake up the host.
