From 57f3a23a3543d3d3ef39de15fb076107895928d1 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Mon, 6 Jan 2014 15:06:10 +0100 Subject: [PATCH 1/5] dt-bindings: document the s3c24xx software-reset register The S3C2412/S3C2413 as well as the S3C2443 and following contain a special register that restarts the system when written to. This adds a simple binding, so that it gets accessible on dt systems too. We distinguish between the two types (s3c2412, s3c2443) because the handling of the swrst register on the s3c2412 also needs to take care of a hardware glitch at reset time.
