[RFC PATCH 0/5] mb96a20s:use DVB core I2C binding and add media controller support

[Mauro Carvalho Chehab <mchehab@osg.samsung.com>]

Those patches are currently experimental and they depend on
this patch:
	https://patchwork.linuxtv.org/patch/27329/

There are 2 cleanup patches here for mb86a20s, and one patch that
converts it to use the new I2C binding helper routines added at the
DVB core.

The next patch extends the DVB core I2C binding routines to add media
controller support for the DVB demod.

The final patch makes cx231xx to register to the media controller,
if the device has a mb86a20s.

Please notice that the current media controller support is actually
too poor and not complete, as it doesn't create and pads to the demod
entity. More work is needed, in order to add the demod pads to it.

That would require some changes at the dvb core, for it to be media
controller aware, and to create the nodes for the DVR and for the other
elements of the DVB graph.

For now, all it shows is:

Media controller API version 0.1.1
