From: Yongqiang Niu <yongqiang.niu@mediatek.com>

Here is two modifition in this patch:
1.bls->dpi0 and rdma1->dsi are differen usecase,
Split DISP_REG_CONFIG_DSI_SEL setting into anther usecase
2.remove DISP_REG_CONFIG_DPI_SEL setting, DPI_SEL_IN_BLS is 0 and
this is same with hardware defautl setting,

[PATCH v3, 12/27] drm/mediatek: move rdma sout from mtk_ddp_mout_en into mtk_ddp_sout_sel

[yongqiang.niu]

From: Yongqiang Niu <yongqiang.niu@mediatek.com>

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

This patch add layer_nr for ovl private data
ovl_2l almost same with with ovl hardware, except the
layer number for ovl_2l is 2 and ovl is 4.
this patch is a preparation for ovl-2l and
ovl share the same driver.

[PATCH v3, 20/27] drm/mediatek: add background color input select function for ovl/ovl_2l

[yongqiang.niu]

From: Yongqiang Niu <yongqiang.niu@mediatek.com>

This patch add background color input select function for ovl/ovl_2l

ovl include 4 DRAM layer and 1 background color layer
ovl_2l include 4 DRAM layer and 1 background color layer
DRAM layer frame buffer data from render hardware, GPU for example.
backgournd color layer is embed in ovl/ovl_2l, we can only set
it color, but not support DRAM frame buffer.

for ovl0->ovl0_2l direct link usecase,
we need set ovl0_2l background color intput select from ovl0
if render send DRAM buffer layer number <=4, all these layer read
by ovl.
layer0 is at the bottom of all layers.
layer3 is at the top of all layers.
if render send DRAM buffer layer numbfer >=4 && <=6
ovl0 read layer0~3
ovl0_2l read layer4~5
layer5 is at the top ot all these layers.

the decision of how to setting ovl0/ovl0_2l read these layer data
is controlled in mtk crtc, which will be another patch

[PATCH v3, 21/27] drm/mediatek: add ovl0/ovl_2l0 usecase

[yongqiang.niu]

From: Yongqiang Niu <yongqiang.niu@mediatek.com>

This patch add ovl0/ovl_2l0 usecase
in ovl->ovl_2l0 direct link usecase:
1. the crtc support layer number will 4+2
2. ovl_2l0 background color input select ovl0 when crtc init
and disable it when crtc finish
3. config ovl_2l0 layer, if crtc config layer number is
bigger than ovl0 support layers(max is 4)

I think you add 'tab' because of "add ovl_2l description for mt8183
display" not "add binding for mt8183 display", so move the 'tab' to the
related patch.

You add 'tab' because of "add mutex mod register offset into ddp private
data" not "add mutex mod into ddp private data", so move this to the
related patch.

You move 2 register setting out of the path from BLS to DPI0, does this
path still work? Please make sure that all modification could work on
all supported SoC.

I does not see any benefit to invent these macro, caller could directly
use data->xxx.

rdma0_sout_sel_in, rdma0_sout_color0, and rdma1_sout_dsi0 are not used
in this patch, so remove from this patch.
