		Any device associated with a device-tree node will have

		an of_path symlink pointing to the corresponding device

		node in /sys/firmware/devicetree/

What:		/sys/devices/*/devspec

Date:		October 2016

Contact:	Device Tree mailing list <devicetree@vger.kernel.org>

Description:

		If CONFIG_OF is enabled, then this file is present. When

		read, it returns full name of the device node.

What:		/sys/devices/*/obppath

Date:		October 2016

Contact:	Device Tree mailing list <devicetree@vger.kernel.org>

Description:

		If CONFIG_OF is enabled, then this file is present. When

		read, it returns full name of the device node.

		write_same_max_bytes is 0, write same is not supported

		by the device.

What:		/sys/block/<disk>/queue/write_zeroes_max_bytes

Date:		November 2016

Contact:	Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com>

Description:

		Devices that support write zeroes operation in which a

		single request can be issued to zero out the range of

		contiguous blocks on storage without having any payload

		in the request. This can be used to optimize writing zeroes

		to the devices. write_zeroes_max_bytes indicates how many

		bytes can be written in a single write zeroes command. If

		write_zeroes_max_bytes is 0, write zeroes is not supported

		by the device.

What:		/sys/block/<disk>/queue/zoned

Date:		September 2016

Contact:	Damien Le Moal <damien.lemoal@hgst.com>

Description:

		zoned indicates if the device is a zoned block device

		and the zone model of the device if it is indeed zoned.

		The possible values indicated by zoned are "none" for

		regular block devices and "host-aware" or "host-managed"

		for zoned block devices. The characteristics of

		host-aware and host-managed zoned block devices are

		described in the ZBC (Zoned Block Commands) and ZAC

		(Zoned Device ATA Command Set) standards. These standards

		also define the "drive-managed" zone model. However,

		since drive-managed zoned block devices do not support

		zone commands, they will be treated as regular block

		devices and zoned will report "none".

What:		/sys/block/<disk>/queue/chunk_sectors

Date:		September 2016

Contact:	Hannes Reinecke <hare@suse.com>

Description:

		chunk_sectors has different meaning depending on the type

		of the disk. For a RAID device (dm-raid), chunk_sectors

		indicates the size in 512B sectors of the RAID volume

		stripe segment. For a zoned block device, either

		host-aware or host-managed, chunk_sectors indicates the

		size of 512B sectors of the zones of the device, with

		the eventual exception of the last zone of the device

		which may be smaller.
