2022-07-15media: videodev2.h: add V4L2_CTRL_FLAG_DYNAMIC_ARRAYHans Verkuil
Add a new flag that indicates that this control is a dynamically sized array. Also document this flag. Currently dynamically sized arrays are limited to one dimensional arrays, but that might change in the future if there is a need for it. The initial use-case of dynamic arrays are stateless codecs. A frame can be divided in many slices, so you want to provide an array containing slice information for each slice. Typically the number of slices is small, but the standard allow for hundreds or thousands of slices. Dynamic arrays are a good solution since sizing the array for the worst case would waste substantial amounts of memory.

Add a helper macro for the situations where a non-MC driver needs to call a state-operation (operation which takes a subdev state as a parameter) in try-context in another subdev. The macro allocates a new subdev state for the called subdev and frees the state afterwards. An example use case is a media platform driver testing if a v4l2_subdev_format would be accepted by a source subdev. This should not be used in MC drivers.

2022-07-15Merge tag 'asoc-v5.20' of ↵Takashi Iwai
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v5.20 This is a big release thus far and there will probably be more changes to come, it's a combination of a larger than usual crop of new drivers and some subsysetm wide cleanups from Charles rather than anything structural. The SOF and Intel DSP code both also continue to be very actively developed. - Restructing of the set_fmt() callbacks to be specified in terms of the device rather than with semantics depending on if the device is supposed to be a CODEC or SoC, making things clearer in situations like CODEC to CODEC links. - Clean up of the way we flag which DAI naming scheme we use to reflect the progress that's been made modernising things. - Merge of more of the Intel AVS driver stack, including some board integrations. - New version 4 mechanism for communication with SOF DSPs. - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms. - Improvements for CODEC to CODEC support in the generic cards. - Support for AMD Jadeite and various machines, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780.
2022-07-15drm/scheduler: Don't kill jobs in interrupt contextDmitry Osipenko
Interrupt context can't sleep. Drivers like Panfrost and MSM are taking mutex when job is released, and thus, that code can sleep. This results into "BUG: scheduling while atomic" if locks are contented while job is freed. There is no good reason for releasing scheduler's jobs in IRQ context, hence use normal context to fix the trouble.
