[PATCH v2 0/2] watchdog: Add Aspeed watchdog driver

[Joel Stanley]

Hello,

These patches add support for the watchdog timer found in Aspeed ast2400 and
ast2500 BMC SoCs.

The u-boot that ships on the edk and with many systems leaves the watchdog
running when jumping to the kernel, making this driver required for operation.

It has been tested on the ast2400 in an OpenPower Palmetto, and the ast2500-edk
dev board.

Changes in v2:

Addressed review from Guenter:
 - dropped the drv_dbgs
 - added defines for all of the constants
 - clarified the type of reset we want
 - leaves the watchdog running

This also updates the device tree compatible string following review from Rob.
As Arnd already took my device tree tree, I will send him a patch to fix that.

Cheers,

Joel
