[PATCH v5, 19/32] drm/medaitek: add layer_nr for ovl private data
From: Yongqiang Niu
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 v5, 11/32] drm/mediatek: split DISP_REG_CONFIG_DSI_SEL setting into another use case
From: Yongqiang Niu
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 v5, 18/32] drm/mediatek: add gmc_bits for ovl private data
From: Yongqiang Niu
This patch add gmc_bits for ovl private data
GMC register was set RDMA ultra and pre-ultra threshold.
10bit GMC register define is different with other SOC, gmc_thrshd_l not

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)

[PATCH v5, 21/32] drm/mediatek: add background color input select function for ovl/ovl_2l
From: Yongqiang Niu
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 v4, 14/33] drm/mediatek: move rdma sout from mtk_ddp_mout_en into mtk_ddp_sout_sel
From: 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

[PATCH v4, 20/33] drm/medaitek: add layer_nr for ovl private data
From: Yongqiang Niu
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.

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)

[PATCH v4, 22/33] drm/mediatek: add background color input select function for ovl/ovl_2l
From: Yongqiang Niu
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

From: Yongqiang Niu
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, 18/27] drm/medaitek: add layer_nr for ovl private data
From: Yongqiang Niu
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, 12/27] drm/mediatek: move rdma sout from mtk_ddp_mout_en into mtk_ddp_sout_sel
From: 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
