Some SoCs not support pre-multiplied pixel formats and extending
configuration of OVL pre-multiplied color formats, such as MT8173.
Fix the SoC degradation problem by this sreies.
---
Change in v5:
Add fix patch for mtk_plane
Change in v4:
Add lost cases of mtk_ovl_fmt_convert_with_blend
Change in v3:
Change MACRO approach to function pointer in driver data
Change in v2:
Fix build error and typo
Change in v1:
Add fix patch for OVL unsupport color format settings by driver data

OVL_CON_CLRFMT_MAN is a configuration for extending color format
settings of DISP_REG_OVL_CON(n).
It will change some of the original color format settings.
Take the settings of (3 << 12) for example.
- If OVL_CON_CLRFMT_MAN = 0 means OVL_CON_CLRFMT_RGBA8888.
- If OVL_CON_CLRFMT_MAN = 1 means OVL_CON_CLRFMT_PARGB8888.
Since OVL_CON_CLRFMT_MAN is not supported on previous SoCs,
It breaks the OVL color format setting of MT8173.
Therefore, the fmt_convert function pointer is added to the driver data
and mtk_ovl_fmt_convert_with_blend is implemented for MT8192 and MT8195
that support OVL_CON_CLRFMT_MAN, and mtk_ovl_fmt_convert is implemented
for other SoCs that do not support it to solve the degradation problem.

Since some SoCs support premultiplied pixel formats but some do not,
the blend_modes parameter is added to mtk_plane_init(), which is
obtained from the mtk_ddp_comp_get_blend_modes function implemented
in different OVL components.
The OVL component can use driver data to set the blend mode
capabilities for different SoCs.

When blend_modes has no pre-multiplied, fmt_convert is mtk_ovl_fmt_convert().
When blend_modes pre-multiplied, fmt_convert is mtk_ovl_fmt_convert_with_blend().
I think we could keep blend_modes and drop fmt_convert.
if (data->blend_modes & BIT(DRM_MODE_BLEND_PREMULTI))
mtk_ovl_fmt_convert_with_blend(fmt, blend_modes);
else
mtk_ovl_fmt_convert(fmt);
In current patch, when SoC does not support pre-multiplied but user space set pre-multiplied buffer,
driver would keep going and treat it as coverage buffer.
I think the result is wrong but it's error handling.
If we accept this error, why not keep only mtk_ovl_fmt_convert_with_blend() and drop mtk_ovl_fmt_convert().
if (data->blend_modes & BIT(DRM_MODE_BLEND_PREMULTI))
mtk_ovl_fmt_convert_with_blend(fmt, blend_modes);
else
mtk_ovl_fmt_convert_with_blend(fmt, blend_modes);
and this would result in:
mtk_ovl_fmt_convert_with_blend(fmt, blend_modes);

RDMA has no alpha blending function.

For disp_rdma, blend_modes is 0, I this is not necessary to create blend mode property.

Yes, OVL in previous SoCs only support the color format with coverage
mode, even if user space set pre-multiplied buffer.
I'll write the comment in this part of code.

OK I'll drop the function pointer and use blend_modes to cope with
this.
