As expected, patch 12 and patch 13 should remain functionally 
independent. They should be logically self-contained even without patch 
14. Otherwise, patch 14 would need to incorporate those panel operations 
via panel_bridge as well.

Both patch 12 and patch 13 have been independently validated on the 
RK3588S EVB1.

Best regards,
Damon
