This allows drivers for devices connected via SPI to check if the
controller supports a given bits_per_word value during setup.
Currently any BPW value is accepted durings setup, and transfers
are rejected later.

Some displays need 9 bit long SPI transfers (Command/Data flag plus
8 bit data). FBTFT has emulation code in case the controller only
supports 8 bit transfers, but this is only used if the controller
setup function reports an error if bits_per_word is set to 9.

Instead of relying on media subtype, use the new macros to detect
if an entity is a subdev or an A/V DMA entity.
Please note that most drivers assume that there's just AV_DMA or
V4L2 subdevs. This is not true anymore, as we've added MC support
for DVB, and there are plans to add support for ALSA a

The struct media_entity does not have an .id field anymore since
now the entity ID is stored in the embedded struct media_gobj.
This caused the omap4iss driver fail to build. Fix by using the
media_entity_id() macro to obtain the entity ID.

Now that a link can be either between two different graph
objects, we'll need to add more functions to create links.
So, rename the existing one that create links only between
two pads as media_create_pad_link().
No functional changes.

This driver is abusing MEDIA_ENT_T_V4L2_SUBDEV:
- it uses a hack to check if the remote entity is a subdev;
- it still uses the legacy entity subtype check macro, that
will be removed soon.

The struct media_entity has a .parent field that stores a pointer
to the parent struct media_device. But recently a media_gobj was
embedded into the entities and since struct media_gojb already has
a pointer to a struct media_device in the .mdev field, the .parent

On omap3/omap4/davinci drivers, MEDIA_ENT_T_V4L2_SUBDEV macro is
abused in order to "simplify" the pad checks.
Basically, it does a logical or of this macro, in order to check
for a local index and if the entity is either a subdev or not.
As we'll get rid of MEDIA_ENT_T_V4L2_SUBDEV macro, replace

Oh! Sorry! I made the changes to correct the faults you figured out.
Is it okay now?
