void XDpPsu_HpdInterruptHandler

(

XDpPsu *

InstancePtr

)

This function is the interrupt handler for the XDpPsu driver.

When an interrupt happens, it first detects what kind of interrupt happened, then decides which callback function to invoke.

Parameters

InstancePtr

is a pointer to the XDpPsu instance.

Returns
