Subject: Re: Using fixed LPI number for some Device ID

 Hi Marc,
    Sorry to disturb you, Currently the LPI number is not fixed for the device. The LPI number is dynamically allocated start from 8092.
 For two OS which shares the ITS, One OS needs to configure the device interrupt required by another OS, and the other OS uses a fixed interrupt
 ID to respond the interrupt. Therefore, the LPI IRQ number of the device needed be fixed. I want to upstream this feature that allocate fixed
 LPI number for the device that is specified through the DTS. What is your meaning?  Thanks
