[PATCH 1/2] drm/i915/dsi: lose the loose 666 format name in favor of packed

[Jani Nikula]

The enum mipi_dsi_pixel_format defines MIPI_DSI_FMT_RGB666 for the
"loose" 24 bpp format and MIPI_DSI_FMT_RGB666_PACKED for the 18 bpp
format. We have this the other way round, defining a loose version for
24 bpp.

Follow suit with what's in enum mipi_dsi_pixel_format to avoid future
confusion. Rename

VID_MODE_FORMAT_RGB666 -> VID_MODE_FORMAT_RGB666_PACKED
VID_MODE_FORMAT_RGB666_LOOSE -> VID_MODE_FORMAT_RGB666

[PATCH 2/2] drm/i915/dsi: start using enum mipi_dsi_pixel_format

[Jani Nikula]

A small step moving us closer to DRM MIPI DSI code. Use enum
mipi_dsi_pixel_format instead of our own. The first benefit is being
able to use common mipi_dsi_pixel_format_to_bpp().

There's a little back and forth conversion with the VBT -> enum ->
register, since we have just shoved the VBT value into the register
directly. Longer term, all the VBT parsing and deciphering should be
done in intel_bios.c, and abstracted there.

This goes against our spec a bit, and the DSI spec calls these
"packed" and "loosly packed". So I'm not entirely thrilled about the
names used in the mipi_dsi_pixel_format either. I think the best
option would be to call them something like 666_18 and 666_24 to
avoid all the confusion.

But patch looks sane anyway so

Agreed, but for now I think conforming to mipi_dsi_pixel_format is the
least bad option.

[PATCH 1/2] drm/i915/dsi: lose the loose 666 format name in favor of packed

[Jani Nikula]

The enum mipi_dsi_pixel_format defines MIPI_DSI_FMT_RGB666 for the
"loose" 24 bpp format and MIPI_DSI_FMT_RGB666_PACKED for the 18 bpp
format. We have this the other way round, defining a loose version for
24 bpp.

Follow suit with what's in enum mipi_dsi_pixel_format to avoid future
confusion. Rename

VID_MODE_FORMAT_RGB666 -> VID_MODE_FORMAT_RGB666_PACKED
VID_MODE_FORMAT_RGB666_LOOSE -> VID_MODE_FORMAT_RGB666
