From 6c7ae2bfc9f052b89c4a874842a6f44cc2e1f0a9 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 30 Nov 2016 16:27:14 +0800 Subject: [PATCH] sunxi: Fix watchdog reset function for R40 The watchdog found on the R40 SoC is the older variant found on the A20. Add the proper "#if defines" to make it work.
