attention_indicator_control:
If an Attention Indicator is implemented, writes to this field will set the
Attention Indicator to the written state. Reads of this field reflect the value
from the latest write, even if the corresponding hot-plug command is not
executed yet at the VPP, unless software issues a write without waiting for
the previous command to complete in which case the read value is
undefined.
00: Reserved.
01: On
10: Blink (Processor drives 1 Hz square wave)

01: On
10: Blink (Processor drives 1 Hz square wave)
11: Off
IIO does not generated the Attention_Indicator_On/Off/Blink messages on
PCI Express when this field is written to by software.

hot_plug_interrupt_enable:
When set to 1b, this bit enables generation of Hot-Plug interrupt MSI or INTx
interrupt depending on the setting of the MSI enable bit in MSICTRL on
enabled Hot-Plug events, provided ACPI mode for hotplug is disabled.
0: disables interrupt generation on Hot-plug events
1: enables interrupt generation on Hot-plug events
0: disables interrupt generation on Hot-plug events
1: enables interrupt generation on Hot-plug events

command_completed_interrupt_enable:
This field enables software notification Interrupt - MSI/INTx or WAKE when a
command is completed by the Hot-plug controller connected to the PCI
Express port
0: disables hot-plug interrupts on a command completion by a hot-plug
0: disables hot-plug interrupts on a command completion by a hot-plug
Controller
1: Enables hot-plug interrupts on a command completion by a hot-plug
1: Enables hot-plug interrupts on a command completion by a hot-plug
Controller

presence_detect_changed_enable:
This bit enables the generation of hot-plug interrupts or wake messages via a
presence detect changed event.
0: disables generation of hot-plug interrupts or wake messages when a
0: disables generation of hot-plug interrupts or wake messages when a
presence detect changed event happens.

mrl_sensor_changed_enable:
This bit enables the generation of hot-plug interrupts or wake messages via a
MRL Sensor changed event.
0: disables generation of hot-plug interrupts or wake messages when an MRL
0: disables generation of hot-plug interrupts or wake messages when an MRL
Sensor changed event happens.
1: Enables generation of hot-plug interrupts or wake messages when an MRL
