This is exactly my initial propose. Can we give a try and manage on board level?
The kernel should not rely on the IOMUX setting done by the bootloader.
Do you use 0x80000000 in your dts IOMUX configuration by any chance?
0x80000000 means that the kernel will not do IOMUX configuration and will use the IOMUX value that comes from the bootloader.
It seems you can fix your USB problem by not using the IOMUX value from the bootloader and just use the good IOMUX (without SION) explicitly in your dts.
Does it fix the problem?
