Subject: [PATCH v2 0/6] Update Davinci watchdog driver

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
