The Allwinner R40 SoC is marketed as the successor to the A20 SoC.
The R40 is a smaller chip than the A20, but features the same set
of programmable pins, with a couple extra pins and some new pin
functions. The chip features 4 Cortex-A7 cores and a Mali-400 MP2
GPU. It retains most if not all features from the A20, while adding
some new features, such as MIPI DSI output, or updating various
hardware blocks, such as DE 2.0.

The TCONs on A31/A31s can select either backend as its input. As there
is no configurable mux in the backend or DRC to redirect their output,
or for the DRC to select an input, the connections are presumably from
the each DRC to each TCON, with the TCON having two input ports, like
the following diagram:

	Backend 0  -------  DRC 0  ------- [0]  TCON 0
				   --   -- [1]
                                     \ /
				      X
