[char-misc-next v4 0/7] mei: create proper iAMT watchdog driver

[Tomas Winkler <tomas.winkler@intel.com>]

Instead of integrating the iAMT watchdog within the mei core driver
we will create a watchdog device on the mei client bus and
create a proper watchdog driver for it.

V4:
1. Rebase the code over patchset : "watchdog: Replace driver based refcounting"
2. Address comments from Guenter
3. Drop one unrelated patch from the series

V3:
1. Revert to dynamically allocated watchdog device wrapper
2. Export activation state to via debugfs
3. Move runtime unregistration to the BDW patch

V2: 
1. The watchdog device is no longer dynamically allocated in separate structure
2. Export device internal status via debugfs
3. Address few comments from Guenter
4. Reworked de/registration

The patches should apply and compile char-misc-next
trees/branches, though the new changes from whatchdog-next are required for proper
execution.
I would prefer this will go via char-misc-next as this is the tree
we work against.

Tomas Winkler (4):
  watchdog: mei_wdt: implement MEI iAMT watchdog driver
  watchdog: mei_wdt: add status debugfs entry
  mei: bus: whitelist the watchdog client
