2022-01-17drm/bridge: sii902x: add support for DRM_BRIDGE_ATTACH_NO_CONNECTORNeil Armstrong
This adds support for DRM_BRIDGE_ATTACH_NO_CONNECTOR by adding the bridge get_edid() and detect() callbacks after refactoring the connector get_modes() and connector_detect() callbacks. In order to keep the bridge working, extra code in get_modes() has been moved to more logical places.

2022-01-17drm/panfrost: initial dual core group GPUs supportAlexey Sheplyakov
On a dual core group GPUs (such as T628) fragment shading can be performed over all cores (because a fragment shader job doesn't need coherency between threads), however vertex shading requires to be run on the same core group as the tiler (which always lives in core group 0). As a first step to support T628 power on only the first core group (so no jobs are scheduled on the second one). This makes T628 look like every other Midgard GPU (and throws away up to half the cores). With this patch panfrost is able to drive T628 (r1p0) GPU on some armv8 SoCs (in particular BE-M1000). Without the patch rendering is horribly broken (desktop is completely unusable) and eventually the GPU locks up (it takes from a few seconds to a couple of minutes). Using the second core group requires support in Mesa (and an UABI change): the userspace should 1) set PANFROST_JD_DOESNT_NEED_COHERENCY_ON_GPU flag to opt-in to allowing the job to run across all cores. 2) set PANFROST_RUN_ON_SECOND_CORE_GROUP flag to allow compute jobs to be run on the second core group (at the moment Mesa does not advertise compute support on anything older than Mali T760) But there's little point adding such flags until someone (myself) steps up to do the Mesa work.

2022-01-13drm/panfrost: Merge some feature listsAlyssa Rosenzweig
Now that we only list features of interest to kernel space, lots of GPUs have the same feature bits. To cut down on the repetition in the file, merge feature lists that are identical between similar GPUs. Note that this leaves some unmerged identical Bifrost feature lists, as there are more features affecting Bifrost kernel space that we do not yet handle.

2022-01-13drm/panfrost: Remove features meant for userspaceAlyssa Rosenzweig
Early versions of the legacy kernel driver included comprehensive feature lists for every GPU, even though most of the enumerated features only matter to userspace. For example, HW_FEATURE_INTERPIPE_REG_ALIASING was a feature bit indicating that a GPU had "interpipe register aliasing": arithmetic, load/store, and texture instruction all use common general-purpose registers. GPUs without this feature bit have dedicated load/store and texture "registers". Whether a GPU has this feature or not is irrelevant to the kernel; it only matters in the userspace compiler's register allocator. It's silly to enumerate it in kernel space, and the information is understandably unused. To underscore the point, this feature only makes sense in the context of the Midgard instruction set. Bifrost never had dedicated load/store or texture registers, so the feature bit was vacuously set for all Bifrost hardware, even though this conveys no useful information. To clean up the feature list, delete feature bits which could not possibly matter to the kernel, leaving only those which do affect the register-level operation of the chip.

2022-01-06drm: omapdrm: Fix implicit dma_buf fencingIvaylo Dimitrov
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.

2022-01-06drm/plane: Make format_mod_supported truly optionalJosé Expósito
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.

2022-01-05drm/bridge: parade-ps8640: Link device to ensure suspend/resume orderAngeloGioacchino Del Regno
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.
