From 601db217916de339ddebeb3b6f024f09a275562a Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 2 Sep 2021 17:57:49 -0500 Subject: [PATCH] dt-bindings: watchdog: sunxi: Add compatibles for D1 D1 keeps the same register layout and clock sources as the R329, but it adds a key field which must be set to update the watchdog's "CFG" and "MODE" registers. Therefore it is not backward-compatible. Similarly to the R329, the D1 has three watchdog instances, and only one of them has the "soft reset" registers. So that instance needs an extra compatible string.
