From mboxrd@z Thu Jan 1 00:00:00 1970 From: wens@csie.org (Chen-Yu Tsai) Date: Wed, 27 May 2015 00:54:16 +0800 Subject: [PATCH] ARM: dts: sun9i: Add device node for watchdog Message-ID: <1432659256-13278-1-git-send-email-wens@csie.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
