Merge tag 'media/v5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab: - New sensor driver: ov5693 - A new driver for STM32 Chrom-ART Accelerator - Added V4L2 core helper functions for VP9 codec - Hantro driver has gained support for VP9 codecs - Added support for Maxim MAX96712 Quad GMSL2 Deserializer - The staging atomisp driver has gained lots of improvements, fixes and cleanups. It now works with userptr - Lots of random driver improvements as usual * tag 'media/v5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (397 commits) media: ipu3-cio2: Add support for instantiating i2c-clients for VCMs media: ipu3-cio2: Call cio2_bridge_init() before anything else media: ipu3-cio2: Defer probing until the PMIC is fully setup media: hantro: Add support for Allwinner H6 media: dt-bindings: allwinner: document H6 Hantro G2 binding media: hantro: Convert imx8m_vpu_g2_irq to helper media: hantro: move postproc enablement for old cores media: hantro: vp9: add support for legacy register set media: hantro: vp9: use double buffering if needed media: hantro: add support for reset lines media: hantro: Fix probe func error path media: i2c: hi846: use pm_runtime_force_suspend/resume for system suspend media: i2c: hi846: check return value of regulator_bulk_disable() media: hi556: Support device probe in non-zero ACPI D state media: ov5675: Support device probe in non-zero ACPI D state media: imx208: Support device probe in non-zero ACPI D state media: ov2740: support device probe in non-zero ACPI D state media: ov5670: Support device probe in non-zero ACPI D state media: ov8856: support device probe in non-zero ACPI D state media: ov8865: Disable only enabled regulators on error path ...
