charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "Linux-rockchip" Errors-To: linux-rockchip-bounces+linux-rockchip=archiver.kernel.org@lists.infradead.org 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.
