2023-12-14drm/tegra: dpaux: Fix PM disable depth imbalance in tegra_dpaux_probeZhang Shurong
The pm_runtime_enable function increases the power disable depth, which means that we must perform a matching decrement on the error handling path to maintain balance within the given context. Additionally, we need to address the same issue for pm_runtime_get_sync. We fix this by invoking pm_runtime_disable and pm_runtime_put_sync when error returns.

2023-12-14drm/mediatek: Power on/off devices with function pointersHsiao Chien Sung
Different from OVL, OVL adaptor is a pseudo device so we didn't define it in the device tree, consequently, pm_runtime_resume_and_get() called by .atomic_enable() powers on no device. For this reason, we implement a function to power on the RDMAs in OVL adaptor, and the system will make sure the IOMMUs are powered on as well because of the device link (iommus) in the RDMA nodes in DTS. This patch separates power and clock management process, it would be easier to maintain and add extensions.

2023-12-14drm/mediatek: Add component ID to component match structureHsiao Chien Sung
Add component ID to component match structure so we can configure them with a for-loop. The main reason we do such code refactoring is that there is a new hardware component called "Padding" since MT8188, while MT8195 doesn't have this module, we can't use the original logic to manage the components. While MT8195 does not define Padding in the device tree, the corresponding components will be NULL and being skipped by the functions.

Hence its allocation needs to be tracked properly by the resource manager to ensure appropriate availability of the block. changes in v2: - move needs_cdm to topology struct Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/571827/ Link: https://lore.kernel.org/r/20231212205254.12422-10-quic_abhinavk@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

2023-12-14drm/msm/dpu: add dpu_hw_cdm abstraction for CDM blockAbhinav Kumar
CDM block comes with its own set of registers and operations which can be done. In-line with other hardware blocks, this change adds the dpu_hw_cdm abstraction for the CDM block. changes in v4: - used FIELD_PREP() for dpu_hw_cdm_setup_cdwn() operations - change to lowercase hex in dpu_hw_cdm_bind_pingpong_blk() - move disable assignment inside else in dpu_hw_cdm_bind_pingpong_blk() changes in v3: - fix commit text from sub-blk to blk for CDM - fix kbot issue for missing static for dpu_hw_cdm_enable() - fix kbot issue for incorrect documentation style - add more documentation for enums and struct in dpu_hw_cdm.h - drop "enable" parameter from bind_pingpong_blk() as we can just use PINGPONG_NONE for disable cases - drop unnecessary bit operation for zero value of cdm_cfg changes in v2: - replace bit magic with relevant defines - use drmm_kzalloc instead of kzalloc/free - some formatting fixes - inline _setup_cdm_ops() - protect bind_pingpong_blk with core_rev check - drop setup_csc_data() and setup_cdwn() ops as they are merged into enable() Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202312101815.B3ZH7Pfy-lkp@intel.com/ Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/571824/ Link: https://lore.kernel.org/r/20231212205254.12422-8-quic_abhinavk@quicinc.com [DB: Added linux/bitfield.h inclusion] Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

2023-12-13drm/amdgpu/sdma5.2: add begin/end_use ring callbacksAlex Deucher
Add begin/end_use ring callbacks to disallow GFXOFF when SDMA work is submitted and allow it again afterward. This should avoid corner cases where GFXOFF is erroneously entered when SDMA is still active. For now just allow/disallow GFXOFF in the begin and end helpers until we root cause the issue. This should not impact power as SDMA usage is pretty minimal and GFXOSS should not be active when SDMA is active anyway, this just makes it explicit. v2: move everything into sdma5.2 code.
