+       u32 mask;
        u32 val;

mask is not the last element, and mmsys_mt8183_routing_table = {
 {
   DDP_COMPONENT_OVL0, DDP_COMPONENT_OVL_2L0,
   MT8183_DISP_OVL0_MOUT_EN, MT8183_OVL0_MOUT_EN_OVL0_2L
 }
...
so the mask and val will be wrong. CK, do you know what mask we should
set for mt8183? Or can we just set a dummy 0 mask.
Ahhh...mt8183 has own mmsys-table and
i had only changed the default one,so
value is now missing because value is now the mask. I have used same order as
CK to avoid confusion and make it easier
to review.
Afaik you could use same value as value to reset same bits...did this in default routing table too.
Should I create another patch based on this or can you help update the
mt8183 table in this patch?

Thanks
regards Frank
