   4 Subject: [PATCH] wdt: sunxi: Introduce a new compatible for the A10 and A31
   5
   6 For historical reasons, the Allwinner A10 compatibles are not following the
   7 patterns used for this other Allwinner SoCs.
   8
   9 Introduce a new compatible following the usual pattern, and deprecate the olders.
