T1042 and PEX interrupts

Hello,

T1040RM is the QorIQ T1040 Reference Manual. Chapter 5 odf this manual describes internal interrupt sources.

For PCI Express 1-4, internal interrupt numbers are 4-7.  PCI Express 1-4 INTA use internal interrupt numbers 24-27.

NXP linux provides device tree for the T1042RDB board (file t1040si-post.dtsi) with the following interrupt numbers:

- PCI Express 1-4 : 20 to 23

- PCI Express 1-4 INTA : 40 to 43.

Is there an error in the reference manual or in the device tree?

If interrupt vectors are configurable, why fix them in the manual?
