The '-v' flag either seems to have been deprecated in some distros, e.g. Gentoo, or is an alias for '--version' in others. The proposed implementation uses the latter flag only.

The current implementation relies on 'fdformat' to output the version of
'util-linux'. This does not seem to be reliable any longer, as 'fdformat'
does not seem to come preinstalled in all ditros these days.

of 'util-linux' and 'mount' proper, as 'mount' is also a part of the
'util-linux' package.

This change adds functionality to operate on reserved SRAM partitions
described in device tree file. Two partition properties are added,
"pool" and "export", the first one allows to share a specific partition
for usage by a kernel consumer in the same manner as it is done for
the whole SRAM device, and "export" property provides access to some
SRAM area from userspace over sysfs interface. Practically it is
possible to specify both properties for an SRAM partition, however
simultaneous access from a kernel consumer and from userspace is not
serialized, but still the combination may be useful for debugging
purpose.

The change opens the following scenarios of SRAM usage:
* updates in a particular SRAM area specified by offset and size are
  done by bootloader, then this information is utilized by the kernel,
* a particular SRAM area is rw accessed from userspace, the stored
  data is persistent on soft reboots,
* a device driver secures SRAM area for its purposes,
* etc.

Note, strictly speaking the added optional properties describe policy
of SRAM usage, rather than hardware, but here the policy mostly
resembles flash partitions in devicetree, which is undoubtedly
a very popular option but it does not describe hardware.

Merge tag 'extcon-next-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next

Chanwoo writes:

Update extcon for 4.4

Detailed description for patchset:
1. Update the extcon core:
- Modify the unique identification and name of each external connector
  with the additional prefix to clarify both attribute and meaning of
  external connector as following:
: EXTCON_CHG_* mean the charger connector.
: EXTCON_JACK_* mean the jack connector.
: EXTCON_DISP_* mean the display port connector.

- Keep the standard name of USB charging port by refering to the
  "Battery Charging v1.2 Spec and Adopters Agreement"[1] to use
  the standard name of USB charging port as following:
: EXTCON_CHG_USB_SDP /* Standard Downstream Port */
: EXTCON_CHG_USB_DCP /* Dedicated Charging Port */
: EXTCON_CHG_USB_CDP /* Charging Downstream Port */
: EXTCON_CHG_USB_ACA /* Accessory Charger Adapter */
[1] www.usb.org/developers/docs/devclass_docs/BCv1.2_070312.zip

2. Update the extcon-arizona.c driver:
- Support the WM8998 and WM1814 codec for jack detection.
- Support for the ADC mode microphone detection and the general
  purpose switch for pop suppression.
- Fix bug include fixing the headphone detection accuracy
  at the top end of the range and some corrections around
  the use of the microphone clamps.

3. Update the extcon-gpio.c driver:
- Clean-up the extcon-gpio driver and fix minor issue before
  supporting the Device tree binding of it.

4. Clean-up and fix the minor issue for extcon drivers:
- Export OF module alias information for extcon-rt8973a.c and extcon-sm5502.c.
- Fix wrong type of variable of for extcon-rt8973a.c and extcon-sm5502.c.
- Use resource managed API for extcon-axp288.c.

This patch modifies the id and name of external connector with the
additional prefix to clarify both attribute and meaning of external
connector as following:
- EXTCON_CHG_* mean the charger connector.
- EXTCON_JACK_* mean the jack connector.
- EXTCON_DISP_* mean the display port connector.

Following table show the new name of external connector with old name:
--------------------------------------------------
Old extcon name         | New extcon name        |
--------------------------------------------------
EXTCON_TA               | EXTCON_CHG_USB_DCP     |
EXTCON_CHARGE_DOWNSTREAM| EXTCON_CHG_USB_CDP     |
EXTCON_FAST_CHARGER     | EXTCON_CHG_USB_FAST    |
EXTCON_SLOW_CHARGER     | EXTCON_CHG_USB_SLOW    |
--------------------------------------------------
EXTCON_MICROPHONE       | EXTCON_JACK_MICROPHONE |
EXTCON_HEADPHONE        | EXTCON_JACK_HEADPHONE  |
EXTCON_LINE_IN          | EXTCON_JACK_LINE_IN    |
EXTCON_LINE_OUT         | EXTCON_JACK_LINE_OUT   |
EXTCON_VIDEO_IN         | EXTCON_JACK_VIDEO_IN   |
EXTCON_VIDEO_OUT        | EXTCON_JACK_VIDEO_OUT  |
EXTCON_SPDIF_IN         | EXTCON_JACK_SPDIF_IN   |
EXTCON_SPDIF_OUT        | EXTCON_JACK_SPDIF_OUT  |
--------------------------------------------------
EXTCON_HMDI             | EXTCON_DISP_HDMI       |
EXTCON_MHL              | EXTCON_DISP_MHL        |
EXTCON_DVI              | EXTCON_DISP_DVI        |
EXTCON_VGA              | EXTCON_DISP_VGA        |
--------------------------------------------------

And, when altering the name of USB charger connector, EXTCON refers to the
"Battery Charging v1.2 Spec and Adopters Agreement"[1] to use the standard
name of USB charging port as following. Following name of USB charging port
are already used in power_supply subsystem. We chan check it on patch[2].
- EXTCON_CHG_USB_SDP	/* Standard Downstream Port */
- EXTCON_CHG_USB_DCP	/* Dedicated Charging Port */
- EXTCON_CHG_USB_CDP	/* Charging Downstream Port */
- EXTCON_CHG_USB_ACA	/* Accessory Charger Adapter */
