[Intel-gfx] [RFC PATCH 1/2] drm/i915/dsi: rename the current DSI legacy

[Jani Nikula]

Starting from ICL we have a new DSI block which requires completely
different programming from the current implementation. Having them in
the same file would be confusing. Rename the current DSI out of the way
as legacy DSI, to make way for the ICL+ implementation. We'll want to
call the new DSI block "intel_dsi".

Are there any reasonable alternatives to "legacy"?

Where we have the encoder implementations for different platforms in the
same file, the names would be platform derived. In the DSI case, we
could call this "BYT DSI" after the first platform with DSI support in
i915, and name the files and functions accordingly. byt_dsi.c,
byt_dsi_pll.c, byt_dsi_init(), and so on.
