Subject: ARM: dts: sun9i: Add device node for watchdog
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6d6693c8a7ca305e531aa3bf6a03e8545e294719;p=linux-beck.git

ARM: dts: sun9i: Add device node for watchdog

On A80 there are 2 watchdogs, one in the main block, and one in the
R (special) block. We do not have information on the R block watchdog,
other than the register layout is the same, and the interrupt number.
Both are able to reset the whole system.

Add the main watchdog, in case the R block is used for special purposes
like running an RTOS.
