[PATCH v5 12/18] drm/rockchip: vop2: Support for different layer select configuration between VPs

Andy Yan
2024-12-09T12:33:52Z

In the upcoming VOP for rk3576, every VP has it's own LAYER_SEL
register, and the configuration value of each VP for the same
window maybe different, so extend the layer_sel_id to array,
let it can descption the layer select configuration value for
different VP.
