Currently omapdrm driver does not initialize dma_buf_export_info resv member, which leads to a new dma_resv being allocated and attached to the exported dma_buf. This leads to the issue that fences created on dma_buf objects imported by other drivers are ignored by omapdrm, as only fences in gem object resv are waited on. This leads to various issues like displaying incomplete frames. Fix that by initializing dma_buf resv to the resv of the gem object being exported. Signed-off-by:

The documentation for "drm_plane_funcs.format_mod_supported" reads: This *optional* hook is used for the DRM to determine if the given format/modifier combination is valid for the plane. This allows the DRM to generate the correct format bitmask (which formats apply to which modifier), and to validate modifiers at atomic_check time. *If not present*, then any modifier in the plane's modifier list is allowed with any of the plane's formats. However, where the function is not present, an invalid IN_FORMATS blob property with modifiers but no formats is exposed to user-space. This breaks the latest Weston [1]. For testing purposes, I extracted the affected code to a standalone program [2]. Make "create_in_format_blob" behave as documented.

Entering suspend while the display attached to this bridge is still on makes the resume sequence to resume the bridge first, display last: when this happens, we get a timeout while resuming the bridge, as its MCU will get stuck due to the display being unpowered. On the other hand, on mt8173-elm, closing the lid makes the display to get powered off first, bridge last, so at resume time the sequence is swapped (compared to the first example) and everything just works as expected. Add a stateless device link to the DRM device that this bridge belongs to, ensuring a correct resume sequence and solving the unability to correctly resume bridge operation in the first mentioned example.

Some display panels would come up with a non-DSI output, those can have an option to connect the DSI host by means of interface bridge converter. This DSI to non-DSI interface bridge converter would requires DSI Host to handle drm bridge functionalities in order to DSI Host to Interface bridge. This patch convert the existing to a drm bridge driver with a built-in encoder support for compatibility with existing component drivers. Signed-off-by:

The dsi has several constraints on the video modes it can support, mainly due to the frequencies that can be generated by the PLL integrated in the DSI device. Verify that the required HS clock can be generated by the PLL. The dsi clock from the dsi PLL and the ltdc pixel clock are asynchronous. The dsi needs to return in LP mode during HFP or HBP to re-synchronize at each video line. Verify that the duration of HFP and HBP allows the dsi to enter in LP mode. Signed-off-by:

eDP 1.4 adds a table of link rates supported by the sink to DPCD, as well as a LINK_RATE_SET register to select between the entries in it. If present, we will use this data to generate our internal link rate table rather than using the standard list based on MAX_LINK_RATE. Some recent laptops report MAX_LINK_RATE=0, and require this support. Signed-off-by:
