Re: [RFC PATCH 2/2] ARM: i.MX: dts: add fsl, imx25-wdt compatible to all relevant watchdog nodes

Hi Vladimir,

Watchdog device controller found on all modern SoCs from i.MX series

watchdog controllers on i.MX21, i.MX27 and i.MX31, the latter
controlles don't have WICR (and pretimeout notification support) and
WMCR registers. To get benefit from the more advanced watchdog device
and to avoid operations over non-existing registers on legacy SoCs add
fsl,imx25-wdt compatible to descriptions of all i.MX25 compatible
watchdog controllers.

Maybe also update Documentation/devicetree/bindings/watchdog/fsl-imx-wdt.txt? 
In a separate patch.
