"mediatek,mt8183-display" is undefined. I think this should be
"mediatek,mt8183-mmsys" and you have met the same problem in [1]. You
may depend on that series to develop your patches.

I prefer adding disp-ovl-2l to be an independent patch.

"mediatek,mt8183-display" is undefined. I think this should be
"mediatek,mt8183-mmsys" and you have met the same problem in [1]. You

Why not just define as:
#define DISP_REG_MUTEX_MOD(mutex_mod_reg, n) (mutex_mod_reg + 0x20 *
(n))
The mutex_mod_reg inside a structure or not is decided by the caller.

Why not just define as:
#define DISP_REG_MUTEX_MOD(mutex_mod_reg, n) (mutex_mod_reg + 0x20 *
(n))
The mutex_mod_reg inside a structure or not is decided by the caller.

mutex0 SOF register offset not always 0x30.
for mt8183, that offset will be 0x2C,
add this regsiter offset into private data

I think you do two things in this patch. One is mutex0 SOF register
offset, and another is making sof value variable. So please split this
into two patches.

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,

It looks like this patch is part of patch 'add mmsys private data for
ddp path config', so I would like you squash this patch into that patch.

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 mmsys private data for ddp path config
all these register offset and value will be different in future SOC
add these define into mmsys private data

This patch add mmsys private data for ddp path config
all these register offset and value will be different in future SOC
add these define into mmsys private data

This patch add mmsys private data for ddp path config
all these register offset and value will be different in future SOC
add these define into mmsys private data

Why do you create a function to select reg_data, I think you could just
add reg_data in struct mtk_mmsys_driver_data so you don't need a
function to select it.

Why do you create a function to select reg_data, I think you could just
add reg_data in struct mtk_mmsys_driver_data so you don't need a
function to select it.

I think this component is the OVL_2L with index 0, I would like the
naming to be DDP_COMPONENT_OVL_2L0.

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

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

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 function to background color input select for ovl/ovl_2l direct link
for ovl/ovl_2l direct link usecase, we need set background color
input select for these hardware.
this is preparation patch for ovl/ovl_2l usecase

The reason is so strange. You could grep 'readl' in mediatek drm driver,
and you would find that many place need this function.

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

This patch add RDMA fifo size error handle
rdma fifo size will not always bigger than the calculated threshold
if that case happened, we need set fifo size as the threshold

I think this is a work around not a correct solution. Why MT8173 has no
this problem but MT8183 has? Is the formula of threshold different in
MT8173 and MT8183?

fifo size of RDMA0 and RDMA1 in MT8173 are same, which is SZ_8K.
this formula calculate result will not overflow if the screen size is
not big enough.
but fifo size of RDMA1 in MT8183 only SZ_2K, if RDMA1 display with
solution 1080p60hz, this formula calculate result 3483 will overflow
SZ_2K.

RDMA1 with SZ_2K can support up to 1080p60hz, even the formula shows
overflow, is it correct?
The formula shows all resolution something more than 1280x1080@60hz will
overflow SZ_2K, and in this patch all set to maximum value.
The patch should implement different FIFO size depends on RDMA0
(SZ_5K)and RDMA1 (SZ_2K), and use the value from the formula.

RDMA1 with SZ_2K can support up to 1080p60hz, even the formula shows
overflow, is it correct?
The formula shows all resolution something more than 1280x1080@60hz will
overflow SZ_2K, and in this patch all set to maximum value.
The patch should implement different FIFO size depends on RDMA0
(SZ_5K)and RDMA1 (SZ_2K), and use the value from the formula.

RDMA1 with SZ_2K can support up to 1080p60hz, even the formula shows
overflow, is it correct?
The formula shows all resolution something more than 1280x1080@60hz will
overflow SZ_2K, and in this patch all set to maximum value.
The patch should implement different FIFO size depends on RDMA0
(SZ_5K)and RDMA1 (SZ_2K), and use the value from the formula.

This patch add ovl0/ovl0_2l usecase
in ovl->ovl0_2l direct link usecase:
1. the crtc support layer number will 4+2
2. ovl0_2l background color input select ovl0 when crtc init
and disable it when crtc finish
3. config ovl0_2l layer, if crtc config layer number is
bigger than ovl0 support layers(max is 4)

From: Yongqiang Niu <yongqiang.niu@mediatek.com>
This patch add ovl0/ovl0_2l usecase
in ovl->ovl0_2l direct link usecase:
1. the crtc support layer number will 4+2
2. ovl0_2l background color input select ovl0 when crtc init
and disable it when crtc finish
3. config ovl0_2l layer, if crtc config layer number is
bigger than ovl0 support layers(max is 4)

I think you need not to invent the function mtk_ddp_comp_get_type() to
get the type. Only the component implementing bgclr_in_on() has the
ability to the extend the ovl layer, so you could judge bgclr_in_on()
exist or not to extend the ovl layer.

I think you need not to invent the function mtk_ddp_comp_get_type() to
get the type. Only the component implementing bgclr_in_on() has the
ability to the extend the ovl layer, so you could judge bgclr_in_on()
exist or not to extend the ovl layer.

From: Yongqiang Niu <yongqiang.niu@mediatek.com>
This patch add support for mediatek SOC MT8183
1.ovl_2l share driver with ovl
2.rdma1 share drive with rdma0, but fifo size is different
3.add mt8183 mutex private data, and mmsys private data
4.add mt8183 main and external path module for crtc create

From: Yongqiang Niu <yongqiang.niu@mediatek.com>
This patch add support for mediatek SOC MT8183
1.ovl_2l share driver with ovl
2.rdma1 share drive with rdma0, but fifo size is different
3.add mt8183 mutex private data, and mmsys private data
4.add mt8183 main and external path module for crtc create

From: Yongqiang Niu <yongqiang.niu@mediatek.com>
This patch add support for mediatek SOC MT8183
1.ovl_2l share driver with ovl
2.rdma1 share drive with rdma0, but fifo size is different
3.add mt8183 mutex private data, and mmsys private data
4.add mt8183 main and external path module for crtc create

display hardware clock will not unprepare when
crtc is disable, until crtc is destroyed.
with this patch, hard clock will disable and unprepare
at the same time.

display hardware clock will not unprepare when
crtc is disable, until crtc is destroyed.
with this patch, hard clock will disable and unprepare
at the same time.

I think the upstreamed patch 'drm/mediatek: Implement gem prime
vmap/vunmap function' [1] has the same function of this patch. You could
cherry-pick that patch to your local and need not to upstream this
