2025-12-30drm/bridge: deprecate of_drm_find_bridge()Luca Ceresoli
of_drm_find_bridge() does not increment the returned bridge refcount. of_drm_find_and_get_bridge() is to be used as a replacement.

2025-12-30drm/bridge: add of_drm_find_and_get_bridge()Luca Ceresoli
of_drm_find_bridge() does not increment the refcount for the returned bridge, but that is required now. However converting it and all its users is not realistically doable at once given the large amount of (direct and indirect) callers and the complexity of some. Solve this issue by creating a new of_drm_find_and_get_bridge() function that is identical to of_drm_find_bridge() except also it takes a reference. Then of_drm_find_bridge() will be deprecated to be eventually removed.

2025-12-30ARM: imx_v6_v7_defconfig: Configure CONFIG_SND_SOC_FSL_ASOC_CARD as moduleAlexander Stein
This option explicitly selects other options, e.g. SND_SOC_FSL_SAI. These SAI drivers use DMA which in turn is dependent on CONFIG_IMX_SDMA. SDMA needs a firmware which is not yet present if the driver is built-in. Thus build CONFIG_SND_SOC_FSL_ASOC_CARD to avoid useless driver probe deferrals due to missing DMA channels.

(Jani, Nikula) --v3: - Convert register address offset, from capital to small. (Ankit) - Move mask bits near to register offsets. (Ankit) --v4: - Use _MMIO_TRANS wherever possible. (Jani) --v5: - Added LIVE Value registers for VMAX and FLIPLINE as provided by DMC fw - For pipe B it is temporary and expected to change later once finalised. --v6: - Add live value registers for DCB VMAX/FLIPLINE. --v7: - Correct commit message file. (Jani Nikula) - Add bits in highest to lowest order. (Jani Nikula) --v8: - Register/bitfields indentation changes as per i915_reg.h mentioned format (Jani, Ankit) --v9: - Remove comment.
