[PATCH v3 0/6] Update Davinci watchdog driver

[Ivan Khoronzhuk]

These patches are intended to update Davinci watchdog to use WDT core
and reuse driver for keystone arch, because Keystone uses the similar
IP like Davinci.

See Documentation:
Davinci DM646x - http://www.ti.com/lit/ug/spruer5b/spruer5b.pdf
Keystone - http://www.ti.com/lit/ug/sprugv5a/sprugv5a.pdf

Also:
 - improved to support GET_TIMELEFT option.
 - added "clocks" and "timeout-sec" properties to DT.

Based on
git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone.git
