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.

-- compatible : should be "allwinner,<soc-family>-wdt", the currently supported

- SoC families being sun4i and sun6i
