Changes since v2:
1. Modify key nouns in the description;
2. Add the label of jitao to Co-developed-by;
3. Macro definition address lowercase problem and function naming;
4. Add missing a description of this property in the mtk_dpi_conf.
Change since v1:
1. Modify mt8186 compatiable location.
2. Modify MT8186_DPI_OUTPUT_FORMAT name.
When MT8186 outputs dpi signal, it is necessary to add dual edge output
format control in mmsys.

From: Xinlei Lee <[email protected]>
Dpi output needs to adjust the output format to dual edge for MT8186.
Because MT8186 HW has been modified at that time, SW needs to cooperate.
And the register (MMSYS) reserved for dpi will be used for output
format control (dual_edge/single_edge).

Let's not mention mt8186 in the description to keep the property generic. Also,
this description should say what having 'rgb888_dual_enable = true' indicates
about the hardware (in this case mt8186) and it currently doesn't.
Let's take a step back. What does 'dual enable' mean in this context and how
does it relate to 'dual edge' and the dpi output format? By answering those
questions we can find a description (and maybe variable name) that makes more
sense.

I'm not sure if it would make more sense to have these definitions in the mmsys
header since they're configurations of a register in mmsys' iospace... I think
we can keep them here but at least add a comment above:
/* Values for DPI configuration in MMSYS address space */

The thing is, we also output in rgb888 dual edge format on mt8183 and mt8192,
and therefore set DDR_EN in mtk_dpi_dual_edge(), right? But, as you said, we
don't need to enable this new rgb888_dual_enable variable on those platforms,
only on mt8186. So that's why I don't think the current name/description is
suitable. If the variable only needs to be set on mt8186, it should have a name
and description that shows what is different between mt8186 and the others. But
without containing the "mt8186" name, since this might happen on other SoCs
later on.
My understanding is that even though both mt8186 and mt8192 output in the rgb888
dual edge format, only mt8186 is able to configure the edge setting in MMSYS (so
on mt8192 it would be hardwired to dual edge and not possible to change). So
what I propose is
Name: edge_cfg_in_mmsys
Description: "If the edge configuration for DPI's output needs to be set in MMSYS"
But maybe since you know the hardware, you might be able to find an even better
name/description.
Thanks,
N?colas

Hi Xinlei,
thank you for the detailed explanation of the situation. Based on this, I still
think the name I suggested, "edge_cfg_in_mmsys", and its description, make
sense. If you're also happy with this name and description, then let's go with
that.
Thanks,
