+Mediatek Display Device
+============================
+
+The Mediatek Display Device provides power control to the system.
+
+Required Properties:
+
+- compatible: Should be one of:
+ - "mediatek,mt8183-display"
+
+The Display Device power name are defined in
+include\dt-bindings\power\mt*-power.h
+
+
+Example:
+
+display_components: dispsys@14000000 {
+ compatible = "mediatek,mt8183-display";
+ reg = <0 0x14000000 0 0x1000>;
+ power-domains = <&scpsys MT8183_POWER_DOMAIN_DISP>;

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,

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

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

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