4Description:
5		Writing y/1/on to this file will cause rescan of the bus
6		and devices on the CDX bus. Any new devices are scanned and
7		added to the list of Linux devices and any devices removed are
8		also deleted from Linux.

10		For example::
11
12		  # echo 1 > /sys/bus/cdx/rescan

17Description:
18		Vendor ID for this CDX device, in hexadecimal. Vendor ID is
19		16 bit identifier which is specific to the device manufacturer.
20		Combination of Vendor ID and Device ID identifies a device.

25Description:
26		Device ID for this CDX device, in hexadecimal. Device ID is
27		16 bit identifier to identify a device type within the range
28		of a device manufacturer.
29		Combination of Vendor ID and Device ID identifies a device.

34Description:
35		CDX bus should be disabled before updating the devices in FPGA.
36		Writing n/0/off will attempt to disable the CDX bus and.
37		writing y/1/on will attempt to enable the CDX bus. Reading this file
38		gives the current state of the bus, 1 for enabled and 0 for disabled.

40		For example::
41
42		  # echo 1 > /sys/bus/cdx/.../enable

47Description:
48		Writing y/1/on to this file resets the CDX device.
49		On resetting the device, the corresponding driver is notified
50		twice, once before the device is being reset, and again after
51		the reset has been complete.
52
53		For example::
54
55		  # echo 1 > /sys/bus/cdx/.../reset

57What:		/sys/bus/cdx/devices/.../remove
58Date:		March 2023
59Contact:	[email protected]
60Description:
61		Writing y/1/on to this file removes the corresponding
62		device from the CDX bus. If the device is to be reconfigured
63		reconfigured in the Hardware, the device can be removed, so
64		that the device driver does not access the device while it is
65		being reconfigured.
66
67		For example::
68
69		  # echo 1 > /sys/bus/cdx/devices/.../remove
