I would like you to add 'dt-bindings' in title.

Usually, the commit title shows 'WHAT' does this patch do, commit
message shows 'WHY' does this patch do, and commit body shows 'HOW' does
this patch do. This commit message just show WHAT does this patch do but
does not show WHY. Maybe this is trivial for you but not for everyone.
So describe more about why you do this.
In addition, 'add mutex mode' and 'add sof' are two things, so break
these two modification into two patches.

It looks like that both mt8173_mutex_sof and mt2701_mutex_sof are subset
of mt2712_mutex_sof, so I think you could keep only mt2712_mutex_sof and
mt8173 and mt2701 also use this one.

Hi, Yongqiang:

Usually, the commit title shows 'WHAT' does this patch do, commit
message shows 'WHY' does this patch do, and commit body shows 'HOW' does
this patch do. This commit message just show WHAT does this patch do but
does not show WHY. Maybe this is trivial for you but not for everyone.
So describe more about why you do this.
In addition, 'add mutex mode' and 'add sof' are two things, so break
these two modification into two patches.

It looks like that both mt8173_mutex_sof and mt2701_mutex_sof are subset
of mt2712_mutex_sof, so I think you could keep only mt2712_mutex_sof and
mt8173 and mt2701 also use this one.

I would like you to change 'reg' to 'id' because you change the usage of
this variable.

You don't use config_regs anymore, drop it.

You can directly return BLS_TO_DSI_RDMA1_TO_DPI1.

I (kind of) understand the change above, as you still end up writing
BLS_TO_DSI_RDMA1_TO_DPI1 in DISP_REG_CONFIG_OUT_SEL.
This changes the behaviour, as now you only write
BLS_TO_DPI_RDMA1_TO_DSI to DISP_REG_CONFIG_OUT_SEL, but the previous
revision of the code would also write to DISP_REG_CONFIG_DSI_SEL and
DISP_REG_CONFIG_DPI_SEL. Why?

Why this change? I don't see mtk_ddp_sout_sel being used later in the
series, so I'm not sure why we don't directly write the value into the
register.

You don't use config_regs anymore, drop it.

You can directly return BLS_TO_DSI_RDMA1_TO_DPI1.

I (kind of) understand the change above, as you still end up writing
BLS_TO_DSI_RDMA1_TO_DPI1 in DISP_REG_CONFIG_OUT_SEL.
This changes the behaviour, as now you only write
BLS_TO_DPI_RDMA1_TO_DSI to DISP_REG_CONFIG_OUT_SEL, but the previous
revision of the code would also write to DISP_REG_CONFIG_DSI_SEL and
DISP_REG_CONFIG_DPI_SEL. Why?

Why this change? I don't see mtk_ddp_sout_sel being used later in the
series, so I'm not sure why we don't directly write the value into the
register.

the format of "mtk_ddp_sout_sel"was not flexible, after we add more
mediatek SOC support, that will be redundant
set this function format like mtk_ddp_mout_en and mtk_ddp_sel_in

DPI_SEL_IN_BLS is 0 for DISP_REG_CONFIG_DPI_SEL set, and hardware
default setting is also 0, so this one is no need anymore

in the patch "[PATCH 04/18] drm/mediatek: move rdma sout from
mtk_ddp_mout_en into mtk_ddp_sout_sel", i moved all rdma out to here,
rdma only have single out, no multi out.
if keep this format, there will many writel_relaxed in mtk_ddp_sout_sel.
and modify this format like mtk_ddp_mout_en and mtk_ddp_sel_in looks
better.

DISP_REG_CONFIG_DSI_SEL set in the next lines.
DPI_SEL_IN_BLS is 0 for DISP_REG_CONFIG_DPI_SEL set, and hardware
default setting is also 0, so this one is no need anymore

in the patch "[PATCH 04/18] drm/mediatek: move rdma sout from
mtk_ddp_mout_en into mtk_ddp_sout_sel", i moved all rdma out to here,
rdma only have single out, no multi out.
if keep this format, there will many writel_relaxed in mtk_ddp_sout_sel.
and modify this format like mtk_ddp_mout_en and mtk_ddp_sel_in looks
better.

This needs to be 2 patches:
1. Make the change to "cur == DDP_COMPONENT_BLS && next ==
DDP_COMPONENT_DPI0", along with an explanation of why this is
reasonable.
2. Change the format to look like mtk_ddp_mout_en and mtk_ddp_sel_in

Ok, but where is mtk_ddp_sout_sel(DDP_COMPONENT_RDMA1,
DDP_COMPONENT_DSI0) called from?
Before this change, we just needed to call:
mtk_ddp_sout_sel(DDP_COMPONENT_BLS, DDP_COMPONENT_DSI0)
and the following 3 registers would be modified:
BLS_TO_DPI_RDMA1_TO_DSI, DSI_SEL_IN_RDMA, DPI_SEL_IN_BLS.
Now, to get similar behaviour, we need to call:
mtk_ddp_sout_sel(DDP_COMPONENT_BLS, DDP_COMPONENT_DSI0)
mtk_ddp_sout_sel(DDP_COMPONENT_RDMA1, DDP_COMPONENT_DSI0)
Maybe that's ok, but you really need to explain the reason for this
change in the commit message.

That's somewhat reasonable, but this needs to be at the very least
described in the commit message.

Ok, but where is mtk_ddp_sout_sel(DDP_COMPONENT_RDMA1,
DDP_COMPONENT_DSI0) called from?
Before this change, we just needed to call:
mtk_ddp_sout_sel(DDP_COMPONENT_BLS, DDP_COMPONENT_DSI0)
and the following 3 registers would be modified:
BLS_TO_DPI_RDMA1_TO_DSI, DSI_SEL_IN_RDMA, DPI_SEL_IN_BLS.
Now, to get similar behaviour, we need to call:
mtk_ddp_sout_sel(DDP_COMPONENT_BLS, DDP_COMPONENT_DSI0)
mtk_ddp_sout_sel(DDP_COMPONENT_RDMA1, DDP_COMPONENT_DSI0)
Maybe that's ok, but you really need to explain the reason for this

I don't really get what this does, but is it intentional that you
don't use gmc_thrshd_l here?
Also, if you only ever use 8 or 10 bits gmc, maybe it's easier to
hard-code the 2 values?
if (ovl->data->gmc_bits == 10)
gmc_value = OVL_RDMA_MEM_GMC_10BIT;
else
gmc_value = OVL_RDMA_MEM_GMC_8BIT; //0x40402020

I don't really get what this does, but is it intentional that you
don't use gmc_thrshd_l here?
Also, if you only ever use 8 or 10 bits gmc, maybe it's easier to
hard-code the 2 values?

GMC register was set RDMA ultra and pre-ultra threshold.
MT8183 GMC register define is different with other SOC, gmc_thrshd_l not
used here.

Ok cool. My issue is that this really appears to be like a mistake, so
maybe it's better to only compute gmc_thrshd_l in the else branch?
gmc_thrshd_h = GMC_THRESHOLD_HIGH >>
(GMC_THRESHOLD_BITS - ovl->data->gmc_bits);
if (ovl->data->gmc_bits == 10) {
gmc_value = gmc_thrshd_h | gmc_thrshd_h << 16;
} else {
gmc_thrshd_l = GMC_THRESHOLD_LOW >>
(GMC_THRESHOLD_BITS - ovl->data->gmc_bits);
gmc_value = gmc_thrshd_l | gmc_thrshd_l << 8 |
gmc_thrshd_h << 16 | gmc_thrshd_h << 24;

I could not see anywhere you use these function. If the function is
useless, drop this patch.

Could you describe more about how ovl-2l works? I guess that ovl-2l is a
ovl hardware which has 3 layer, the bottom two layer is from DRAM and
the top layer is from another hardware (maybe the ovl). If my guess is
correct, why not just implement this function in mtk_ovl_layer_on()? In
mtk_ovl_layer_on(), you could do as
if (idx == ovl->data->layer_nr) {
mtk_ddp_write_mask((1 << 2), comp,
DISP_REG_OVL_DATAPATH_CON, OVL_BGCLR_SEL_IN);
return;
}
So does mtk_ovl_layer_off().

It looks like that mt81830-rdma0 and mt8183-rdma1 are different in
hardware, so I think fifo_size should be decided by something from
device tree rather than from its name. Maybe add a property 'FIFO_SIZE'
in rdma device node or create an additional compatible string for
mt8183-rdma1.
