'F.7.3.6.1 General slice segment header syntax' section of HEVC specification describes that a slice header always end aligned on byte boundary, therefore we only need to provide the data offset in bytes.

The number of 'entry point offset' can be very variable. Instead of using a large static array define a v4l2 dynamic array of U32 (V4L2_CTRL_TYPE_U32). The number of entry point offsets is reported by the elems field and in struct v4l2_ctrl_hevc_slice_params.num_entry_point_offsets field.

The HEVC specification describes the following: "PicOrderCntVal is derived as follows: PicOrderCntVal = PicOrderCntMsb + slice_pic_order_cnt_lsb The value of PicOrderCntVal shall be in the range of −2^31 to 2^31 − 1, inclusive."

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.

stm32-dcmi calls its source subdev with v4l2_subdev_call() using a v4l2_subdev_state constructed on stack. This means that init_cfg is never called for that state, and a source subdev that depends on the init_cfg call may break. A new macro has been added for this particular purpose, which properly initializes the state, so let's use v4l2_subdev_call_state_try() here.

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.

This partially reverts commit fd9f8050, and changes things so that the capability string fields of the encoder conform to their requirements. The driver name field should contain the actual driver name, not some otherwise unused string macro from the driver. To make this clear, copy the name from the driver's name field. The card name for the video encoder previously held a static platform name that was fixed to match MT8173. This obviously doesn't make sense for newer chips. Since commit fd9f8050 ("media: mediatek: vcodec: Change encoder v4l2 capability value"), this field was changed to hold the driver's name, or "mtk-vcodec-dec". This doesn't make much sense either, since this still doesn't reflect what chip this is. Instead, fill in the card name with "MTxxxx video encoder" with the proper chip number. Since commit f2d8b691 ("media: v4l: ioctl: Set bus_info in v4l_querycap()"), the V4L2 core provides a default value for the bus_info field for platform and PCI devices. This value will match the default value for media devices added by commit cef69974 ("media: mc: Set bus_info in media_device_init()"). These defaults are stable and device-specific. Drop the custom capability bus_info from the mtk-vcodec encoder driver, and use the defaults. As this patch removes the last usage of MTK_VCODEC_DRV_NAME, remove the macro as well.

This partially reverts commit a8a7a278, and changes things so that the capability string fields of the decoder conform to their requirements. This recent change caused ChromeOS's decoder to no longer function. This is due to ChromeOS using the driver name field to match the video device with its accompanying media device. After the change, they no longer matched. The driver name field should contain the actual driver name, not some otherwise unused string macro from the driver. To make this clear, copy the name from the driver's name field. The card name for the video decoder previously held a static platform name that was fixed to match MT8173.

Drop the custom capability bus_info from the mtk-vcodec decoder driver, and use the defaults. This also fixes the long standing issue where the media device used for the stateless decoder didn't have its bus_info set, and would never match its accompanying video device.
