2019-10-23	Documentation: Link to API section in Docs	Laurent Pinchart
	The API belongs to the docs section. Link to it from docs.rst, and remove the shortcut in the navigation bar as links to a placeholder only. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2019-01-11	Documentation: Add placeholder for Doxygen-generated API documentation	Laurent Pinchart
	Until we have better Sphinx + Doxygen integration, replace the relative external link to the API documentation with a placeholder directory, which will be populated with the Doxygen-generated doc when exporting documentation to the website. This is needed as the Sphinx documentation is exported to the root of the website, linking to ../api-html is thus not possible. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
