I think this needs some changes. I think our general approach to these
version differences should be such that the component in question (dispc
in this case) should ask from somewhere what the DSS version is, and
then using that version, handle the different versions internally.
What that means related to this patch is that we should keep all those
functions static, and initialize the dispc_ops structure inside dispc.c.
However, we don't have any such "DSS version" yet. I have previously
wanted to move the cpu_is checks to one place (dss_features), but I
think it's probably cleaner if we allow cpu_is checks in the other files
also. However, there should be only one place in the file where those
should be.
So I think we should have something like this, called from
omap_dispchw_probe():
static void dispc_init_features(void)
{
if (cpu_is_foo())
setup features for this omap;
else if (...)
...
}
This would setup the ops, or whatever is needed. This function would be
the only place in dispc.c that contains cpu_is checks.
