From ac45fe6b0056d1f92b7c7e5f13514b591a6a9caf Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime.ripard@free-electrons.com>

Subject: [PATCH] wdt: sunxi: Introduce a new compatible for the A10 and A31
For historical reasons, the Allwinner A10 compatibles are not following the
patterns used for this other Allwinner SoCs.
Introduce a new compatible following the usual pattern, and deprecate the olders.
