Merge tag 'media/v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: - v4l core: subdev frame interval now supports which field - v4l kapi: moves and renames the init_cfg pad op to init_state as an internal op. - new sensor drivers: gc0308, gc2145, Avnet Alvium, ov64a40, tw9900 - new camera driver: STM32 DCMIPP - s5p-mfc has gained MFC v12 support - new ISP driver added to staging: Starfive - new stateful encoder/decoded: Wave5 codec It is found on the J721S2 SoC, JH7100 SoC, ssd202d SoC. Etc. - fwnode gained support for MIPI "DisCo for Imaging" (https://www.mipi.org/specifications/mipi-disco-imaging) - as usual, lots of cleanups, fixups and driver improvements. * tag 'media/v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (309 commits) media: i2c: thp7312: select CONFIG_FW_LOADER media: i2c: mt9m114: use fsleep() in place of udelay() media: videobuf2: core: Rename min_buffers_needed field in vb2_queue media: i2c: thp7312: Store frame interval in subdev state media: docs: uAPI: Fix documentation of 'which' field for routing ioctls media: docs: uAPI: Expand error documentation for invalid 'which' value media: docs: uAPI: Clarify error documentation for invalid 'which' value media: v4l2-subdev: Store frame interval in subdev state media: v4l2-subdev: Add which field to struct v4l2_subdev_frame_interval media: v4l2-subdev: Turn .[gs]_frame_interval into pad operations media: v4l: subdev: Move out subdev state lock macros outside CONFIG_MEDIA_CONTROLLER media: s5p-mfc: DPB Count Independent of VIDIOC_REQBUF media: s5p-mfc: Load firmware for each run in MFCv12. media: s5p-mfc: Set context for valid case before calling try_run media: s5p-mfc: Add support for DMABUF for encoder media: s5p-mfc: Add support for UHD encoding. media: s5p-mfc: Add support for rate controls in MFCv12 media: s5p-mfc: Add YV12 and I420 multiplanar format support media: s5p-mfc: Add initial support for MFCv12 media: s5p-mfc: Rename IS_MFCV10 macro ...
