I think you should directly define these value as symbols because now
only support one SoC.
#define MODEL "mtk-camsys-3.0"
#define INPUT_NR 4
#define MUTEX_NR 6
#define OUTPUT_NR 4
Because we don't know which SoC would be upstream later, maybe the next
SoC would be
static const struct mtk_seninf_conf seninf_83xx_conf = {
.model = "mtk-camsys-3.0",
.nb_inputs = 4,
.nb_muxes = 6,
.nb_outputs = 4,
.support_xxx = true;
};
then model, nb_inputs, nb_muxes, and nb_outputs has no difference, so
it's not necessary to define them as variable. So define them as
constant now, and when next SoC upstream, then we know which one would
be variable.
