Rename to struct v4l2_vp8_loop_filter, which is closer to the VP8 syntax. This change is only cosmetics, but since this API is exposed to userspace, it's worth the trouble to get it consistent. Signed-off-by:

It doesn't seem to add any clarity to have a "header" suffix in controls, struct names and flags. Since this just makes names too long without any benefit, just drop it. Signed-off-by:

On production devices the firmware could be located on different places, this path could be provided by special firmware-name DT property. Here we check for existence of such DT property and if it exist take the firmware path from there. Otherwise, if the property is missing we fallback to the predefined path from driver resource structure. Signed-off-by:

Commit aaaa93ed ("media] media: venus: venc: add video encoder files") is the last in a series of three commits to add core.c vdec.c and venc.c adding core, encoder and decoder. The encoder and decoder check for core drvdata as set and return -EPROBE_DEFER if it has not been set, however both the encoder and decoder rely on core.v4l2_dev as valid. core.v4l2_dev will not be valid until v4l2_device_register() has completed in core.c's probe(). Normally this is never seen however, Dmitry reported the following backtrace when compiling drivers and firmware directly into a kernel image. [ 5.259968] Hardware name: Qualcomm Technologies, Inc.

In practice, IA_CSS_PIPE_ID_NUM should never be used when calling atomisp_q_video_buffers_to_css(), as the driver should discover the right pipe before calling it. Yet, if some pipe parsing issue happens, it could end using it. So, add a WARN_ON() to prevent such case. Reported-by:

Define macros for the fields of the MIPI_CSIS_DPHY_BCTRL_L register, based on the i.MX8MM datasheet. The numerical value written to the register, taken from the i.MX7D code, is unchanged, and corresponds to a 20.0MHz Tx escape clock frequency according to the documentation of the register from the i.MX8MM. Whether the other fields are applicable to the i.MX7D is unknown. While at it, rename the DPHY[BS]CTRL register names to DPHY_[BS]CTRL to match the datasheet. Signed-off-by:

When setting the CSIS parameters, write the MIPI_CSIS_DPHYCTRL register fully instead of modifying selected fields, as the register doesn't contain any reserved fields that need to be preserved. This simplifies initialization slightly, and ensures that the register value doesn't depend on its previous state (before a warm reboot for instance). Signed-off-by:

The data type specified for 10-bit YUV is the same as 8-bit YUV. This is wrong, and has thus clearly not been tested. Instead of fixing data type without being able to test it, drop it. It can be added back later when someone will have access to a 10-bit YUV source to this it. Signed-off-by:

The wrap clock is retrieved with the other clocks using devm_clk_bulk_get(), and retrieved independently with a specific devm_clk_get() call.
