For gic bindings, The 3rd cell of interrupts is the flags,encoded as follows: bits[3:0] trigger type and level flags. 1 = low-to-high edge triggered 2 = high-to-low edge triggered 4 = active high level-sensitive 8 = active low level-sensitive bits[15:8] PPI interrupt cpu mask.
Please refer to Documentation/devicetree/bindings/arm/gic.txt for detailed information.
In Foundation model and RTSM model's device tree, the 3rd cell of interrupts of all devices is 4, so we should use active high level-sensitive in the DSDT table too when we convert the device to ACPI.

Nice catch. This looks like something to be sent upstream -- have you done that? We should include it regardless.
