    wlcore: set irq_trigger in board files instead of hiding behind a quirk
    
    The platform_quirk element in the platform data was used
    to change the way the IRQ is triggered.  When set,
    the EDGE_IRQ quirk would change the irqflags used
    and treat edge trigger differently from the rest.
    
    Instead of hiding this irq flag setting behind the quirk,
    have the board files set the irq_trigger explicitly.
    
    This will allow us to use standard irq DT definitions
    later on.

因此、我认为在 DTS 中使用"中断"关键字来指定 IRQ 标志就足够了。我们目前正在使用以下工具：

中断=<14 IRQ_TYPE_LEVEL_HIGH>；

您知道边沿触发中断是否更适合 imx6？以上所有这些链接都指定了 IMX6的平台奇怪-用于表示"平台不支持电平触发中断"-这表明...？如何检查 IRQ 配置是否正常工作？

具体而言、我不熟悉 IMX6平台、但 wlcore 驱动程序支持级别和边缘管理。我的建议是、如果您有疑虑、可以使用 EDGE。

中断=<14 IRQ_TYPE_EDGE_RISING >；

如果您能够在平台上启动驱动程序、则可以检查 IRQ 是否正常工作。您还应该会在"ifconfig "中看到 wlan0接口。如果它不工作、您可以共享 dmesg 日志。
