2025-05-21drm/bridge: adv7511: switch to the HDMI connector helpersDmitry Baryshkov
Rewrite the ADV7511 driver to use implementation provided by the DRM HDMI connector framework, including the Audio and CEC bits. Drop the in-bridge connector support and use drm_bridge_connector if the host requires the connector to be provided by the bridge. Note: currently only AVI InfoFrames are supported. Existing driver doesn't support programming any other InfoFrames directly and Audio InfoFrame seems to be programmed using individual bits and pieces rather than programming it directly.

2025-05-21drm/display: add CEC helpers codeDmitry Baryshkov
Add generic CEC helpers to be used by HDMI drivers. Both notifier and and adapter are supported for registration. Once registered, the driver can call common set of functions to update physical address, to invalidate it or to unregister CEC data. Unlike drm_connector_cec_funcs (which provides interface common to all implementations, including, but not limited to the CEC adapter, CEC notifier, CEC pin-based adapter, etc) the struct drm_connector_hdmi_cec_adapter_ops provides callbacks specific to the CEC adapter implementations.

2025-05-21drm/display: move CEC_CORE selection to DRM_DISPLAY_HELPERDmitry Baryshkov
THe Kconfig symbol DRM_DISPLAY_DP_AUX_CEC is a boolean which simply toggles whether DP_AUX_CEC support should be built into the drm_display_helper (which can be eithera module or built-in into the kernel). If DRM_DISPLAY_DP_AUX_CEC is selected, then CEC_CORE is selected to be built-in into the kernel even if DRM_DISPLAY_HELPER is selected to be built as a module.

2025-05-21drm/connector: add CEC-related fieldsDmitry Baryshkov
As a preparation to adding HDMI CEC helper code, add CEC-related fields to the struct drm_connector. The callbacks abstract CEC infrastructure in order to support CEC adapters and CEC notifiers in a universal way. CEC data is a void pointer as it allows us to make CEC data helper-specific. For example, currently it will be either cec_notifier or cec_adapter + drm_connector_hdmi_cec_funcs. Later cec-pin might store platform callbacks here. DP CEC might need to store AUX pointer, etc. Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Maxime Ripard <mripard@kernel.org> Link: https://lore.kernel.org/r/20250517-drm-hdmi-connector-cec-v6-3-35651db6f19b@oss.qualcomm.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>

2025-05-20drm/tidss: Update infrastructure to support K3 DSS cut-down versionsDevarsh Thakkar
SoCs like AM62Lx support cut-down version of K3 DSS where although same register space is supported as in other K3 DSS supported SoCs such as AM65x, AM62x, AM62Ax but some of the resources such as planes and corresponding register spaces are truncated. For e.g. AM62Lx has only single VIDL pipeline supported, so corresponding register spaces for other video pipelines need to be skipped. To add a generic support for future SoCs where one or more video pipelines can get truncated from the parent register space, move the video plane related information to vid_info struct which will also have a field to indicate hardware index of each of the available video planes, so that driver only maps and programs those video pipes and skips the unavailable ones. While at it, also change the num_planes field in the features structure to num_vid so that all places in code which use vid_info structure are highlighted in the code.

2025-05-20drm/i915/dp_mst: Work around Thunderbolt sink disconnect after ↵Imre Deak
SINK_COUNT_ESI read Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT link may get disconnected inadvertently if the SINK_COUNT_ESI and the DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX transaction. Work around the issue by reading these registers in separate transactions. The issue affects MTL+ platforms and will be fixed in the DP-in adapter firmware, however releasing that firmware fix may take some time and is not guaranteed to be available for all systems. Based on this apply the workaround on affected platforms. See HSD #13013007775. v2: Cc'ing Mika Westerberg.

Rename intel_dpll to intel_dpll_global so that intel_shared_dpll can be renamed to intel_dpll in an effort to move away from the shared naming convention. Also intel_dpll according to it's comment tracks global dpll rather than individual hence making more sense this gets changed.

2025-05-19drm/rockchip: cleanup fb when drm_gem_fb_afbc_init failedAndy Yan
In the function drm_gem_fb_init_with_funcs, the framebuffer (fb) and its corresponding object ID have already been registered. So we need to cleanup the drm framebuffer if the subsequent execution of drm_gem_fb_afbc_init fails. Directly call drm_framebuffer_put to ensure that all fb related resources are cleanup.

2025-05-19drm/xe/guc: Make creation of SLPC debugfs files conditionalAradhya Bhatia
Platforms that do not support SLPC are exempted from the GuC PC support. The GuC PC does not get initialized, and neither do its BOs get created. This causes a problem because the GuC PC debugfs file is still being created. Whenever the file is attempted to read, it causes a NULL pointer dereference on the supposed BO of the GuC PC. So, make the creation of SLPC debugfs files conditional to when SLPC features are supported.

2025-05-19drm/i915/vrr: Program EMP_AS_SDP_TL for DP AS SDPAnkit Nautiyal
The register EMP_AS_SDP_TL (MTL) was introduced for configuring the double buffering point and transmission line for all HDMI2.1 Extended Metadata Packets (VT-EMP for VRR, CVT-EMP for DSC etc). This was also intended to be configured for DP to HDMI2.1 PCON to support VRR. From BMG and LNL+ onwards, this register was extended to Display Port Adaptive Sync SDP to have a common register to configure double buffering point and transmission line for both HDMI EMPs and DP VRR related packets. Currently, we do not support VRR for either native HDMI or via PCON. However we need to configure this for DP SDP case. As per the spec, program the register to set Vsync start as the double buffering point for DP AS SDP. v2: -Make the helper more readable. (Jani) -Add more information in commit message and comment.

This is required enable the higher frequencies. - Drop fictional `address_space_size`. For some older devices, the address space size is limited to 4GB to avoid potential 64b rollover math problems in the fw. For these, an `ADRENO_QUIRK_4GB_VA` quirk is added. For everyone else we get the address space size from the SMMU `ias` (input address sizes), which is usually 48b. - Improve robustness when GMU HFI responses time out - Fix crash when throttling GPU immediately during boot - Fix for rgb565_predicator on Adreno 7c3 - Remove `MODULE_FIRMWARE()`s for GPU, the GPU can load the firmware after probe and having partial set of fw (ie. sqe+gmu but not zap) causes problems MDSS: - Added SAR2130P support to MDSS driver DPU: - Changed to use single CTL path for flushing on DPU 5.x+ - Improved SSPP allocation code to allow sharing of SSPP between planes - Enabled SmartDMA on SM8150, SC8180X, SC8280XP, SM8550 - Added SAR2130P support - Disabled DSC support on MSM8937, MSM8917, MSM8953, SDM660 - Misc fixes DP: - Switch to use new helpers for DP Audio / HDMI codec handling - Fixed LTTPR handling DSI: - Added support for SA8775P - Added SAR2130P support MDP4: - Fixed LCDC / LVDS controller on HDMI: - Switched to use new helpers for ACR data - Fixed old standing issue of HPD not working in some cases Signed-off-by: Dave Airlie <airlied@redhat.com> From: Rob Clark <robdclark@gmail.com> Link: https://lore.kernel.org/r/CAF6AEGv2Go+nseaEwRgeZbecet-h+Pf2oBKw1CobCF01xu2XVg@mail.gmail.com

Some older NVIDIA and some newer NVIDIA hardware/firmware seems to have issues with address only transactions (firmware rejects them). Add an option to the core drm dp to avoid address only transactions, This just puts the MOT flag removal on the last message of the transfer and avoids the start of transfer transaction.
