[PATCH_V3 0/2] watchdog: jz4740: Add DT support

[Zubair Lutfullah Kakakhel]

Hi,

Here are two simple patches that add DT support to the jz4740 watchdog driver.

Patches are based on 3.19-rc7. Quite disjoint and stay within jz4740
so should apply easily on other trees.

If you would like to have them rebased to a different tree, please tell.

V3 Changed
Added Reviewed-by: Guenter Roeck <linux@roeck-us.net> 
Typo in commit message.
Rebased to rc7

V2 Changes
Renamed binding to jz4740 instead of jz47xx
Removed clk bindings. They can be added later when the clock tree is fixed.
Rather than add bindings now and change later.

Added MODULE_DEVICE_TABLE()

Thank-you

[PATCH_V3 1/2] dt: watchdog: Add DT binding documentation for jz4740 watchdog timer

[Zubair Lutfullah Kakakhel]

Add binding for jz4740 watchdog timer. It is a simple watchdog timer.

Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com>
Reviewed-by: Guenter Roeck <linux@roeck-us.net>

---
The jz4740 is platform only at the moment.

But DT support is being added

See http://patchwork.linux-mips.org/bundle/paulburton/ci20-v3.20/

V3: Added Reviewed-by: Guenter Roeck <linux@roeck-us.net>

V2 Changes

Removed clock binding because of pending work in clock tree. Will add
binding later. Rather than introduce a bad binding now and change later.

Renamed to jz4740 instead of jz47xx.
