'struct v4l2_mbus_config' is a legacy struct that should not be used
in new drivers. So replace it with the fields:

enum v4l2_mbus_type mbus_type;
unsigned int parallel_bus_flags;

The field 'parallel_bus_flags' is used only for buses of types
V4L2_MBUS_BT656, V4L2_MBUS_PARALLEL which are not yet supported
so they are set to 0.

Hi Dafna,

Thanks for the patch, just a small comment below.

Why not just:

s_asd->parallel_bus_flags = vep->bus.mipi_csi2.flags

So when it gets supported, we don't need to change this, and you also don't
change the logic here, since this patch was supposed to just replace
struct v4l2_mbus_config by other variables.

Make sense?

You check both bus types, I understand that V4L2_MBUS_BT656 is also a parallel interface,
but I think it would be less confusing to name it just bus_flags, what do you think?

Helen
