From: Steve Twiss <[e-mail]>

Add binding information for DA9062 and DA9061 watchdog.

Example bindings for both DA9062 and DA9061 devices are added. For
the DA9061 device, a fallback compatible line is added as a valid
combination of compatible strings.

The original binding for DA9062 (only) used to reside inside the
Documentation/devicetree/bindings/mfd/da9062.txt MFD document.
The da9062-watchdog section was deleted in that file and replaced
with a link to the new DA9061/62 binding information stored in this
patch.

 - Each compatible line should be a valid combination of compatible
   strings, alter DA9061 line to include the fall back compatible string
 - Update the commit message to describe this change
 - Add information about associated patches from this set without
   describing them as being explicitly dependent on this binding

v1 -> v2
 - Patch renamed from [PATCH V1 07/10] to [PATCH V2 02/10] -- these
   changes were made to fix checkpatch warnings caused by the patch
   set dependency order
 - Updated the patch description to be explicit about where parts of
   this binding had originally been stored
 - A second example for DA9061 is provided to highlight the use of a
   fall-back compatible option for the DA9062 watchdog driver

Hi,

No code changes for this version PATCH V5.

As previously:
For the watchdog case: the DA9062 device driver is compatible with the
DA9061 and for this reason there is minimal change required to the DA9062
watchdog device driver. The example for the DA9061 watchdog shows the
use of a fall-back compatible string.

Other information:
The device driver from this patch set (associated with this binding) is
  [PATCH V5 6/8] watchdog: da9061: watchdog driver
 
Regards,
Steve Twiss, Dialog Semiconductor Ltd.
