[RESEND PATCH v6 08/17] drm/mediatek: move rdma sout from mtk_ddp_mout_en into mtk_ddp_sout_sel

[Yongqiang Niu]

This patch move rdma sout from mtk_ddp_mout_en into mtk_ddp_sout_sel
rdma only has single output, but no multi output,
all these rdma->dsi/dpi usecase should move to mtk_ddp_sout_sel

Re: [RESEND PATCH v6 00/17] add drm support for MT8183

Hi, Yongqiang:

This 'RESEND v6' is different with v6, so I think you should call this
v7.

I think "mediatek,rdma_fifo_size" is not a 'required' property. In
mt8173.dtsi [1], there is no mediatek,rdma_fifo_size in rdma0, rdma1,
and rdma2. So I think you should move this to 'optional' property.

Re: [RESEND PATCH v6 03/17] drm/mediatek: move dsi/dpi select input into mtk_ddp_sel_in

I think you have done two things in this patch. One is remove
DISP_REG_CONFIG_DPI_SEL setting, and the other is move
DISP_REG_CONFIG_DSI_SEL from mtk_ddp_sout_sel() to mtk_ddp_sel_in(). So
separate this into two patches.

A new property doesn't really warrant a whole new example.
