[RFC v2 0/5] RCLK watchdog driver

[RFC v2 0/5] RCLK watchdog driver

[Wolfram Sang]

Okay, here is my recent version of the RCLK watchdog driver. It still works for
me only in UP on a r8a7790 ES1 Lager Board. So, this is why it is RFC only. The
complete branch with DTS updates can be found in this branch:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/wdt-on-4.3

I'll do another version with proper timeout handling. And then I'll investigate
what it needs to reuse this driver on r7s72100 Genmai. Maybe we can get this
driver upstream via this way.

Changes since last version:

* rebase to renesas-devel-20151008-v4.3-rc4
* populate timeout value for read
* use 0xffff to trigger reset
* properly populate parent device

Cheers,

   Wolfram
