Hi Simon,

This models some sort of interrupt thingy but there are so many abreviations that I cannot find out what it stands for. It is something to do with interrupts.
After I read the ApolloLake datasheet, the ITSS contains the following parts:
- A register block that is compatible with current "intel,irq-router" driver in U-Boot, plus two more - IOAPIC - Legacy 8254 - Legacy 8259 - Legacy I/O ports like NMI and reset control (0xcf9) - HPET
So it seems to me that the best option for us is to extend current "intel,irq-router" driver to support new capabilities, instead of creating a new "ITSS" uclass driver, which we both don't know that ITSS stands for ...
It supports two operations.
