Commit 567f97bd ("media: ipu3-cio2: support multiple sensors and VCMs with same HID") introduced an on stack vcm_name and then uses this for the name field of the software_node struct used for the vcm. But the software_node struct is much longer lived then the current stack-frame, so this is no good. Instead extend the ipu_node_names struct with an extra field to store the vcm software_node name and use that. Note this also changes the length of the allocated buffer from ACPI_ID_LEN + 4 to 16. the name is filled with "<ipu_vcm_types[x]>-%u" where ipu_vcm_types[x] is not an ACPI_ID. The maximum length of the strings in the ipu_vcm_types[] array is 11 + 5 bytes for "-255\0" means 16 bytes are needed in the worst case scenario.

When ipu_bridge_parse_rotation() and ipu_bridge_parse_orientation() run sensor->adev is not set yet. So if either of the dev_warn() calls about unknown values are hit this will lead to a NULL pointer deref. Set sensor->adev earlier, with a borrowed ref to avoid making unrolling on errors harder, to fix this.

Add support for C-PHY on R-Car V4H. While the V4H supports both D-PHY and C-PHY this patch only adds support for the C-PHY mode due to lack of documentation and hardware to test on. The V4H is the first Gen4 device that is enabled in the rcar-csi2 driver. There is much overlap with the Gen3 driver, the primary difference is in how the receiver is started. The V4H have a much larger register space and some addresses overlap with Gen3. [Sakari Ailus: Use div_u64() to divide a 64-bit integer.] Signed-off-by:

The imx219_set_pad_format() function adjusts the media bus code provided through the v4l2_subdev_format parameter to a media bus code known to be supported by the sensor. The same exact operation is performed by the imx219_get_format_code() function which called by imx219_update_pad_format(), which is in the imx219_set_pad_format() call path. Remove the duplicated operation and simplify imx219_set_pad_format(). Signed-off-by:

The set_fmt and init_cfg functions both fills a v4l2_mbus_framefmt instance, passing in the mode and the media bus code. While set_fmt uses function helpers, init_cfg open-codes the assignments. Simplify the format initialization by moving it to a common helper. Signed-off-by:

The CSI2 specification specifies a standard method to access camera sensor registers called "Camera Control Interface (CCI)". This uses either 8 or 16 bit (big-endian wire order) register addresses and supports 8, 16, 24 or 32 bit (big-endian wire order) register widths. Currently a lot of Linux camera sensor drivers all have their own custom helpers for this, often copy and pasted from other drivers. Add a set of generic helpers for this so that all sensor drivers can switch to a single common implementation. These helpers take an extra optional "int *err" function parameter, this can be used to chain a bunch of register accesses together with only a single error check at the end, rather than needing to error check each individual register access. The first failing call will set the contents of err to a non 0 value and all other calls will then become no-ops.

As selecting V4L2_FWNODE, MEDIA_CONTROLLER and VIDEO_V4L2_SUBDEV_API are now selected by the top level menu, they can be dropped from the individual drivers. Also dropped selecting V4L2_ASYNC for a single driver as this is already implied by V4L2_FWNODE. Similarly, the I2C dependency is now also in the top level menu, so remove it, as well as VIDEO_DEV which isn't needed by camera sensor drivers. Signed-off-by:

Select V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API for all sensor drivers. This also adds the options to drivers that don't specifically need them, these are still seldom used drivers using old APIs. The upside is that these should now all compile --- many drivers have had missing dependencies. The "menu" is replaced by selectable "menuconfig" to select the needed V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API options. Also select MEDIA_CONTROLLER which VIDEO_V4L2_SUBDEV_API effectively depends on, and add the I2C dependency to the menu. Reported-by:

The VIDEO_IMX_MEDIA Kconfig symbol used to select helpers shared between independent drivers for different i.MX SoCs, and VIDEO_IMX_MEDIA then selects drivers specific to the i.MX5 and i.MX6. Now that i.MX7 and i.MX8 support has moved to drivers/media/ and doesn't depend on VIDEO_IMX_CSI, there's no need to have separate Kconfig options. Merge VIDEO_IMX_CSI into VIDEO_IMX_MEDIA.

Commit 1029939b ("media: v4l: async: Simplify async sub-device fwnode matching") recently changed how async sub-device matching works. This breaks the UB9x3 drivers, as they set the subdev.fwnode to an endpoint. Afaiu, the fix is simply to not set subdev.fwnode at all.
