gpio: xgene-sb: set valid IRQ type in to_irq()
xgene-sb is setup to be a hierarchical IRQ chip with the GIC as the
parent chip. xgene_gpio_sb_to_irq() currently sets the default IRQ type
to IRQ_TYPE_NONE, which the GIC loudly complains about with a WARN_ON().
Let's set the initial default to a sane value (IRQ_TYPE_EDGE_RISING)
that was determined by decoding the ACPI tables on affected hardware:
Device (_SB.GPSB)
{
Name (_HID, "APMC0D15") // _HID: Hardware ID
Name (_CID, "APMC0D15") // _CID: Compatible ID
Name (_UID, "GPIOSB") // _UID: Unique ID
...
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
{
...
Interrupt (ResourceConsumer, Edge, ActiveHigh, Exclusive, ,, )
{
0x00000048,
}
...
}
}
This can be overridden later as needed with irq_set_irq_type().
