From: Zubair Lutfullah Kakakhel
Date: Tue Feb 03 2015 - 05:26:41 EST


Add DT support to the jz4740 driver. Simple of_match_ptr. No other
modification for probe needed

V3 Typo in Reviewed-by: Guenter Roeck <linux@xxxxxxxxxxxx>

V2 changes
Add module device table. Even though we are moving to non-dt for jz4740.
Lets try and not break things while at it.

Renamed jz4740_of_match to jz4740_wdt_of_match
