[PATCH 1/3] ARM: dts: sunxi: add R_LRADC support for A83T

[PATCH 1/3] ARM: dts: sunxi: add R_LRADC support for A83T

[Ziping Chen]

From: Ziping Chen <techping.chan-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

The Allwinner A83T's R_LRADC is similiar with the
Allwinner A10's LRADC, they can use the same driver.

Add support for it.

[PATCH 2/3] ARM: dts: sunxi: add MMC support for A83T

[Ziping Chen]

From: Ziping Chen <techping.chan@gmail.com>

The Allwinner A83T's MMC can work with
compatible "allwinner,sun7i-a20-mmc".

Add support for it.

This has been proven not to be the case already.

Please use an A83T compatible only.
