The bridges using HDMI connector framework have a call to drm_atomic_helper_connector_hdmi_check() in their atomic_check() callback. In order to reduce boilerplate and make simplify bridge's code, use drm_atomic_helper_connector_hdmi_check() to implement drm_connector.atomic_check() for HDMI bridges.

2024-12-20drm: panel-simple: support TOPLAND TIAN G07017 LCD panelAhmad Fatoum
The TIAN-G07017-01 is a 7" TFT-LCD module by TOPLAND ELECTRONICS (H.K). The panel features 1024x600 24-bit RGB pixels driven over LVDS as well as a PWM backlight and I2C-connected ft5506-compatible capacitive touch. The panel description is taken from the Datasheet V0 (2024.5.23), but it lists no timings and these were provided by the vendor separately.

2024-12-20drm/bridge:anx7625: Update HDCP content statusXin Ji
When user enabled HDCP feature, userspace will set HDCP content to DRM_MODE_CONTENT_PROTECTION_DESIRED. Next, anx7625 will update HDCP content to DRM_MODE_CONTENT_PROTECTION_ENABLED if down stream support HDCP feature. As anx7625 bridge IC will be power down after call .atomic_disable(), then all HDCP status will be lost on chip. So we should reestablish HDCP again in .atomic_enable(), and update hdcp content to DESIRE if current HDCP content is ENABLE in .atomic_disable(). v4: - Change HDCP content value to DESIRED if HDCP status is ENABLE in bridge interface .atomic_enable(). v3: - Move hdcp content value checking from bridge interface .atomic_check() to .atomic_enable() v2: - Add more details in commit message Signed-off-by: Xin Ji <xji@analogixsemi.com> Tested-by: Pin-yen Lin <treapking@chromium.org> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://lore.kernel.org/r/20241219070330.224996-1-xji@analogixsemi.com Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20241219070330.224996-1-xji@analogixsemi.com
2024-12-19drm/amdgpu: track bo memory stats at runtimeYunxiang Li
Before, every time fdinfo is queried we try to lock all the BOs in the VM and calculate memory usage from scratch. This works okay if the fdinfo is rarely read and the VMs don't have a ton of BOs. If either of these conditions is not true, we get a massive performance hit. In this new revision, we track the BOs as they change states. This way when the fdinfo is queried we only need to take the status lock and copy out the usage stats with minimal impact to the runtime performance. With this new approach however, we would no longer be able to track active buffers.

When memory stats is generated fresh everytime by going though all the BOs, their active information is quite easy to get. But if the stats are tracked with BO's state this becomes harder since the job scheduling part doesn't really deal with individual buffers.

2024-12-19drm/bridge: ti-sn65dsi83: Add ti,lvds-vod-swing optional propertiesAndrej Picej
Add a optional properties to change LVDS output voltage. This should not be static as this depends mainly on the connected display voltage requirement. We have three properties: - "ti,lvds-termination-ohms", which sets near end termination, - "ti,lvds-vod-swing-data-microvolt" and - "ti,lvds-vod-swing-clock-microvolt" which both set LVDS differential output voltage for data and clock lanes. They are defined as an array with min and max values. The appropriate bitfield will be set if selected constraints can be met. If "ti,lvds-termination-ohms" is not defined the default of 200 Ohm near end termination will be used. Selecting only one: "ti,lvds-vod-swing-data-microvolt" or "ti,lvds-vod-swing-clock-microvolt" can be done, but the output voltage constraint for only data/clock lanes will be met. Setting both is recommended.

2024-12-19drm: xlnx: zynqmp_dpsub: Add DP audio supportTomi Valkeinen
Add basic DisplayPort audio support. Support non-live audio playback from two PCMs (DMA channels), and the volume control in the audio mixer. As older dtb files may not have the audio DMA channels defined, the driver will just mark the audio support as disabled if the audio DMA is missing, and will continue with only display support. Note: Reset doesn't seem to work (ZYNQMP_DISP_AUD_SOFT_RESET). If we do a reset, audio playback won't start again even if, afaics, we do set up all the necessary registers. So, at the moment, resetting the audio block in dp_dai_hw_free() is commented out.
