The ACPI DSDT of the Surface Pro X (SQ2) specifies the interrupts for
the secondary UBS controller as
Name (_CRS, ResourceTemplate ()
{
Interrupt (ResourceConsumer, Level, ActiveHigh, Shared, ,, )
{
0x000000AA,
}
Interrupt (ResourceConsumer, Level, ActiveHigh, SharedAndWake, ,, )
{
0x000000A7, // hs_phy_irq: &intc GIC_SPI 136
}
Interrupt (ResourceConsumer, Level, ActiveHigh, SharedAndWake, ,, )
{
0x00000228, // ss_phy_irq: &pdc 40
}
Interrupt (ResourceConsumer, Edge, ActiveHigh, SharedAndWake, ,, )
{
0x0000020A, // dm_hs_phy_irq: &pdc 10
}
Interrupt (ResourceConsumer, Edge, ActiveHigh, SharedAndWake, ,, )
{
0x0000020B, // dp_hs_phy_irq: &pdc 11
}
})
Generally, the interrupts above 0x200 map to the PDC interrupts (as used
in the devicetree) as ACPI_NUMBER - 0x200. Note that this lines up with
dm_hs_phy_irq and dp_hs_phy_irq (as well as the interrupts for the
primary USB controller).
Based on the snippet above, ss_phy_irq should therefore be PDC 40 (=
0x28) and not PDC 7. The latter is according to ACPI instead used as
ss_phy_irq for port 0 of the multiport USB controller). Fix this by
setting ss_phy_irq to '&pdc 40'.
