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

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

Hi Yongqiang Niu,
Thank you for your patch.

I think this change requires a better explanation of what you are

need to create a new mt2701-mmsys file?
> Feature: drm/mediatek
Remove this.

What about doing this

+};
> +struct mtk_mmsys_private_data {

And instead of point to the funcs add the registers data here.

And here

AFAICS these registers are only used here, so you can get them per SoC
and configure properly

And you can do here:
+ const struct mtk_mmsys_driver_data *data;
+
+ data = of_device_get_match_data(dev);
And then use data->regs.ovl0_mout_en where you need it.

What about doing this
+struct mtk_mmsys_reg_data {
+ u32 ovl0_mout_en;
+};
> +struct mtk_mmsys_private_data {
> + void __iomem *config_regs;

And instead of point to the funcs add the registers data here.
const struct mtk_mmsys_reg_data regs;

And here

+ },
AFAICS these registers are only used here, so you can get them per SoC
and configure properly

And you can do here:
+ const struct mtk_mmsys_driver_data *data;
+
+ data = of_device_get_match_data(dev);
And then use data->regs.ovl0_mout_en where you need it.

Hi Yongqiang Niu,
Thank you for your patch.

I think this change requires a better explanation of what you are
doing. Although I'm really uncomfortable with this change, why you
need to create a new mt2701-mmsys file?
> Feature: drm/mediatek
Remove this.

AFAICS these registers are only used here, so you can get them per SoC
and configure properly

And you can do here:
+ const struct mtk_mmsys_driver_data *data;
+
+ data = of_device_get_match_data(dev);
And then use data->regs.ovl0_mout_en where you need it.

What about doing this

+ u32 ovl0_mout_en;
+};
> +struct mtk_mmsys_private_data {

And instead of point to the funcs add the registers data here.

And here

AFAICS these registers are only used here, so you can get them per SoC
and configure properly

And you can do here:
+ const struct mtk_mmsys_driver_data *data;
+
+ data = of_device_get_match_data(dev);
And then use data->regs.ovl0_mout_en where you need it.

I think this is done in [1], [2], [3], this patch just add the support
of mt8183-ovl and mt8183-ovl-2l.

I think this is done in [4], this patch just add the support of mt8183-rdma.

The fourth item is the mmsys private data in third item, so you need
not to repeat it.

I think this array is for 'sof', so you should drop MT8183_MUTEX_EOF_DSI0.

Ditto.

I think this is done in [1], [2], [3], this patch just add the support
of mt8183-ovl and mt8183-ovl-2l.
[1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/gpu/drm/mediatek?h=v5.8-rc6&id=132c6e250ed745443973cada8db17cdbaebdf551

[3] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/gpu/drm/mediatek?h=v5.8-rc6&id=57148baac8b78461e394953cfd5317bde8f795ab
> 2.rdma1 share drive with rdma0, but fifo size is different
I think this is done in [4], this patch just add the support of mt8183-rdma.
[4] https://patchwork.kernel.org/patch/11679549/
> 3.add mt8183 mutex private data, and mmsys private data
> 4.add mt8183 main and external path module for crtc create
The fourth item is the mmsys private data in third item, so you need
not to repeat it.

I think you could implement these three function to be the same as the
three of mt8183 with mt2701 version of mmsys_mout_en[],
mmsys_sel_in[], mmsys_sout_sel[]. If you worry that you could not test
on mt2701, we could temporarily accept this and wait for someone has
mt2701 (or mt8173) to rewrite these three function to be the same as
mt8183.

I think you could implement these three function to be the same as the
three of mt8183 with mt2701 version of mmsys_mout_en[],
mmsys_sel_in[], mmsys_sout_sel[]. If you worry that you could not test

mt2701 (or mt8173) to rewrite these three function to be the same as
mt8183.

I think you could implement these three function to be the same as the
three of mt8183 with mt2701 version of mmsys_mout_en[],
mmsys_sel_in[], mmsys_sout_sel[]. If you worry that you could not test
on mt2701, we could temporarily accept this and wait for someone has
mt2701 (or mt8173) to rewrite these three function to be the same as
mt8183.

I think you could implement these three function to be the same as the
three of mt8183 with mt2701 version of mmsys_mout_en[],
mmsys_sel_in[], mmsys_sout_sel[]. If you worry that you could not test
on mt2701, we could temporarily accept this and wait for someone has
mt2701 (or mt8173) to rewrite these three function to be the same as
mt8183.

hi Chun-Kuang.
thanks very much for your understand.
actually, the display path connection of mt2701, mt2712, mt8173, mt6779,
mt6797 are all different with each other.
there will be mtxx-mmsys.c for every SoC.
and the corresponded SoC upstream member will coding these and test it
on the SoC if it is need.

hi Chun-Kuang.
thanks very much for your understand.
actually, the display path connection of mt2701, mt2712, mt8173, mt6779,
mt6797 are all different with each other.
there will be mtxx-mmsys.c for every SoC.
and the corresponded SoC upstream member will coding these and test it
on the SoC if it is need.

hi Chun-Kuang.
thanks very much for your understand.
actually, the display path connection of mt2701, mt2712, mt8173, mt6779,
mt6797 are all different with each other.
there will be mtxx-mmsys.c for every SoC.
and the corresponded SoC upstream member will coding these and test it
on the SoC if it is need.

reason:
1.there will more and more Mediatek Soc upstream, and the display path
connection function mtk_mmsys_ddp_mout_en, mtk_mmsys_ddp_sel_in and
mtk_mmsys_ddp_sout_sel will complicated more and more,
2. many of the connection are only used in some SoC, and useless for
other SoC and not readable,
3. if we add a new SoC connection, we need check is this affect other
Soc,

can not reused, that why need add mmsys private data like before
version.
but that still not a good idea.
the next path like this will be more readable, and more easy to maintain

reason:
1.there will more and more Mediatek Soc upstream, and the display path
connection function mtk_mmsys_ddp_mout_en, mtk_mmsys_ddp_sel_in and
mtk_mmsys_ddp_sout_sel will complicated more and more,
2. many of the connection are only used in some SoC, and useless for
other SoC and not readable,
3. if we add a new SoC connection, we need check is this affect other
Soc,

can not reused, that why need add mmsys private data like before
version.
but that still not a good idea.
the next path like this will be more readable, and more easy to maintain

reason:
1.there will more and more Mediatek Soc upstream, and the display path
connection function mtk_mmsys_ddp_mout_en, mtk_mmsys_ddp_sel_in and
mtk_mmsys_ddp_sout_sel will complicated more and more,
2. many of the connection are only used in some SoC, and useless for
other SoC and not readable,
3. if we add a new SoC connection, we need check is this affect other
Soc,

reason:
1.there will more and more Mediatek Soc upstream, and the display path
connection function mtk_mmsys_ddp_mout_en, mtk_mmsys_ddp_sel_in and
mtk_mmsys_ddp_sout_sel will complicated more and more,
2. many of the connection are only used in some SoC, and useless for
other SoC and not readable,
3. if we add a new SoC connection, we need check is this affect other
Soc,

Even though EOF and SOF are located in the same hardware register, why
should we set EOF?
We just need mutex hardware to send SOF to MODs, we don't need mutex
to send EOF.

The primary thing of this patch is to get fifo size from device tree.
So you may modify title to show the primary thing.

I would like the description to be "Get the fifo size from device tree
because each rdma in the same SoC may have different fifo size."

You did in the previous series, would that mean that your previous
series were wrong or nonworking or break on some SoCs?
I agree that you need per SoC data, what I am complaining is the idea
of having pointers to functions instead of just having the registers
or the media paths per SoC. You can have private data for registers,
something like this:
static const struct mtk_mmsys_driver_data mt8183_mmsys_driver_data = {
.clk_driver = "clk-mt8183-mm",
.regs = {
.ovl0_mout_en = MT8183_DISP_OVL0_MOUT_EN,
.rdma0_sout_sel_in = MT8183_DISP_RDMA0_SOUT_SEL_IN,
.rdma0_sout_color0 = MT8183_RDMA0_SOUT_COLOR0,
.rdma1_sout_sel_in = MT8183_DISP_RDMA1_SOUT_SEL_IN,
.rdma1_sout_dsi0 = MT8183_RDMA1_SOUT_DSI0,
.dpi0_sel_in = MT8183_DISP_DPI0_SEL_IN,
.dpi0_sel_in_rdma1 = MT8183_DPI0_SEL_IN_RDMA1,
.dsi0_sel_in = MT8183_DISP_DSI0_SEL_IN,
.dsi0_sel_in_rdma1 = MT8183_DSI0_SEL_IN_RDMA1,
},
};
And you can also have the media configuration paths in the driver
data, similar to what you did for mt8183 but not for the others. But,
I'd recommend to do this in a second step, and go step-by-step. Your
v6 and v7 are quite different, but IMHO I'm more in favor of what you
did for v6 (as a first step to support mt8183) than this patchset. For
v7 I was expecting just to move the bits that needed to mtk-mmsys, not
such rework. Said all that, I'm not the maintainer and is up to the
maintainer to decide the direction that driver should take.

Ack, that's more readable and probably should be the direction to go,
always assuming we have the *data* (mmsys_path_sel, etc.) per SoC and
the functions mtk_mmsys_ddp_mout_en(), mtk_mmsys_ddp_sel_in(),
mtk_mmsys_ddp_sout_sel() common for all SoCs.

You did in the previous series, would that mean that your previous
series were wrong or nonworking or break on some SoCs?
I agree that you need per SoC data, what I am complaining is the idea
of having pointers to functions instead of just having the registers
or the media paths per SoC. You can have private data for registers,
something like this:
static const struct mtk_mmsys_driver_data mt8183_mmsys_driver_data = {
.clk_driver = "clk-mt8183-mm",
.regs = {
.ovl0_mout_en = MT8183_DISP_OVL0_MOUT_EN,

And you can also have the media configuration paths in the driver
data, similar to what you did for mt8183 but not for the others. But,
I'd recommend to do this in a second step, and go step-by-step. Your
v6 and v7 are quite different, but IMHO I'm more in favor of what you
did for v6 (as a first step to support mt8183) than this patchset. For
v7 I was expecting just to move the bits that needed to mtk-mmsys, not
such rework. Said all that, I'm not the maintainer and is up to the
maintainer to decide the direction that driver should take.

Ack, that's more readable and probably should be the direction to go,
always assuming we have the *data* (mmsys_path_sel, etc.) per SoC and
the functions mtk_mmsys_ddp_mout_en(), mtk_mmsys_ddp_sel_in(),
mtk_mmsys_ddp_sout_sel() common for all SoCs.

You did in the previous series, would that mean that your previous
series were wrong or nonworking or break on some SoCs?
I agree that you need per SoC data, what I am complaining is the idea
of having pointers to functions instead of just having the registers
or the media paths per SoC. You can have private data for registers,
something like this:
static const struct mtk_mmsys_driver_data mt8183_mmsys_driver_data = {
.clk_driver = "clk-mt8183-mm",
.regs = {
.ovl0_mout_en = MT8183_DISP_OVL0_MOUT_EN,
.rdma0_sout_sel_in = MT8183_DISP_RDMA0_SOUT_SEL_IN,
.rdma0_sout_color0 = MT8183_RDMA0_SOUT_COLOR0,
.rdma1_sout_sel_in = MT8183_DISP_RDMA1_SOUT_SEL_IN,
.rdma1_sout_dsi0 = MT8183_RDMA1_SOUT_DSI0,
.dpi0_sel_in = MT8183_DISP_DPI0_SEL_IN,
.dpi0_sel_in_rdma1 = MT8183_DPI0_SEL_IN_RDMA1,
.dsi0_sel_in = MT8183_DISP_DSI0_SEL_IN,
.dsi0_sel_in_rdma1 = MT8183_DSI0_SEL_IN_RDMA1,
},
};
And you can also have the media configuration paths in the driver
data, similar to what you did for mt8183 but not for the others. But,
I'd recommend to do this in a second step, and go step-by-step. Your
v6 and v7 are quite different, but IMHO I'm more in favor of what you
did for v6 (as a first step to support mt8183) than this patchset. For
v7 I was expecting just to move the bits that needed to mtk-mmsys, not

I agree that you need per SoC data, what I am complaining is the idea

or the media paths per SoC. You can have private data for registers,
something like this:
static const struct mtk_mmsys_driver_data mt8183_mmsys_driver_data = {
.clk_driver = "clk-mt8183-mm",
.regs = {
.ovl0_mout_en = MT8183_DISP_OVL0_MOUT_EN,
.rdma0_sout_sel_in = MT8183_DISP_RDMA0_SOUT_SEL_IN,
.rdma0_sout_color0 = MT8183_RDMA0_SOUT_COLOR0,
.rdma1_sout_sel_in = MT8183_DISP_RDMA1_SOUT_SEL_IN,
.rdma1_sout_dsi0 = MT8183_RDMA1_SOUT_DSI0,
.dpi0_sel_in = MT8183_DISP_DPI0_SEL_IN,
.dpi0_sel_in_rdma1 = MT8183_DPI0_SEL_IN_RDMA1,
.dsi0_sel_in = MT8183_DISP_DSI0_SEL_IN,
.dsi0_sel_in_rdma1 = MT8183_DSI0_SEL_IN_RDMA1,
},
};
And you can also have the media configuration paths in the driver
data, similar to what you did for mt8183 but not for the others. But,
I'd recommend to do this in a second step, and go step-by-step. Your

v7 I was expecting just to move the bits that needed to mtk-mmsys, not
such rework. Said all that, I'm not the maintainer and is up to the
maintainer to decide the direction that driver should take.

Ack, that's more readable and probably should be the direction to go,
always assuming we have the *data* (mmsys_path_sel, etc.) per SoC and
the functions mtk_mmsys_ddp_mout_en(), mtk_mmsys_ddp_sel_in(),
mtk_mmsys_ddp_sout_sel() common for all SoCs.
Thanks,
Enric
