+What:		/sys/bus/cdx/rescan
+Date:		March 2023
+Contact:	nipun.gupta@amd.com
+Description:
+		Writing y/1/on to this file will cause rescan of the bus
+		and devices on the CDX bus. Any new devices are scanned and
+		added to the list of Linux devices and any devices removed are
+		also deleted from Linux.
+
+		For example::
+
+		  # echo 1 > /sys/bus/cdx/rescan
+
+What:		/sys/bus/cdx/devices/.../vendor
+Date:		March 2023
+Contact:	nipun.gupta@amd.com
+Description:
+		Vendor ID for this CDX device, in hexadecimal. Vendor ID is
+		16 bit identifier which is specific to the device manufacturer.
+		Combination of Vendor ID and Device ID identifies a device.

+What:		/sys/bus/cdx/devices/.../enable
+Date:		October 2023
+Contact:	abhijit.gangurde@amd.com
+Description:
+		CDX bus should be disabled before updating the devices in FPGA.
+		Writing n/0/off will attempt to disable the CDX bus and.
+		writing y/1/on will attempt to enable the CDX bus. Reading this file
+		gives the current state of the bus, 1 for enabled and 0 for disabled.
+
+		For example::
+
+		  # echo 1 > /sys/bus/cdx/.../enable

+What:		/sys/bus/cdx/devices/.../reset
+Date:		March 2023
+Contact:	nipun.gupta@amd.com
+Description:
+		Writing y/1/on to this file resets the CDX device or all devices
+		on the bus. On resetting the device, the corresponding driver is
+		notified twice, once before the device is being reset, and again
+		after the reset has been complete.
+
+		For example::
+
+		  # echo 1 > /sys/bus/cdx/.../reset
+
+What:		/sys/bus/cdx/devices/.../remove
+Date:		March 2023
+Contact:	tarak.reddy@amd.com
+Description:
+		Writing y/1/on to this file removes the corresponding
+		device from the CDX bus. If the device is to be reconfigured
+		reconfigured in the Hardware, the device can be removed, so
+		that the device driver does not access the device while it is
+		being reconfigured.
+
+		For example::
+
+		  # echo 1 > /sys/bus/cdx/devices/.../remove

+		where:
+
+		    - vXXXX contains the vendor ID;
+		    - dXXXX contains the device ID;
+		    - svXXXX contains the subsystem vendor ID;
+		    - sdXXXX contains the subsystem device ID;
+		    - cXXXXXX contains the device class.
