Describe structs and enums used to set blend mode properties to MPC blocks. Some pieces of information are already available as code comments, and were just formatted. Others were collected and summarised from discussions on AMD issue tracker[1][2]. [1] https://gitlab.freedesktop.org/drm/amd/-/issues/1734 [2] https://gitlab.freedesktop.org/drm/amd/-/issues/1769 v2: - fix typos (Tales) - add MPCC to MPC entry in the glossary Signed-off-by:

Add details about color correction capabilities and explain a bit about differences between DC hw generations and also how they are mapped between DRM and DC interface. Two schemas for DCN 2.0 and 3.0 (converted to svg from the original png) is included to illustrate it. They were obtained from a discussion[1] in the amd-gfx mailing list. [1] https://lore.kernel.org/amd-gfx/20220422142811.dm6vtk6v64jcwydk@mail.igalia.com/ v1: - remove redundant comments (Harry) - fix typos (Harry) v2: - reword introduction of color section - add co-dev tag for Harry - who provided most of the info - fix typos (Tales) - describe missing struct parameters (Tales and Siqueira) Co-developed-by:

AMDGPU DM maps DRM color management properties (degamma, ctm and gamma) to DC color correction entities. Part of this mapping is already documented as code comments and can be converted as kernel docs. v2: - rebase to amd-staging-drm-next - fix typos (Tales) - undo kernel-docs inside functions (Tales) Signed-off-by:

The timing programming inside DCN is far from trivial, it has multiple parameters associated with that, and the lack of documentation does not help comprehend this already complicated topic. This commit tries to improve this situation by expanding the documentation of dc_crtc_timing and the VTG program function. Reviewed-by:

In the DCN code, we can find some references to three different pipe split policies but no clear description. This commit adds some kernel-doc that explains more about these options and a little bit of their impact. Reviewed-by:

[Why & How] Depending on how the clock table is constructed from PMFW we can run into issues where we don't think we have enough bandwidth available due to FCLK too low - eg. when the FCLK table contains invalid entries or a single entry. We should always pick up the maximum clocks for each state as a final state in this case to prevent validation from failing if the table is malformed. We should also contain sensible defaults in the case where values are invalid. Redfine the clock table structures by adding a 314 prefix to make debugging these issues easier by avoiding symbol name clashes. Overall this policy more closely aligns to how we did things for 315, but because of how the voltage rail is setup we should favor keeping DCFCLK low rather than DISPCLK or DPPCLK - so use the max for those in every entry.

[Why] Recent backport from opensource broke the Nightly tool build that tests DC and DML for bugs and regressions. This was because the backport had a header inclusion that was not consistent with the AMD style of including headers was allowed to be merged back in DML code that caused tool compilation failures. [How] Modify the way in which the header file in included so that it is consistent with AMD style of including headers.
