    Hi Cherry,

    The interrupt router configuration is wrong in 8.6 SDK. This is fixed in 9.0 SDK.

    Here are the 2 patches:

    commit 68ec7433794c13da14e803b477ac6eefd330f243

    arm64: dts: ti: k3-j784s4: Fix the interrupt ranges property for main gpio intr
    
    The parent's input irq number is incorrect for the main_gpio_intr.
    Update the irq number as per the exact numbers in:
    https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/j784s4/interrupt_cfg.html
    
    Fixes: bebe2e3c9a30i ("arm64: dts: ti: Add initial support for J784S4 SoC")

    The above is for main domain GPIO interrupts.

    The above is for wake up domain.
