arm64: dts: qcom: sc8180x: Fix ss_phy_irq for secondary USB controller
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'.
