The v4l2_flash_init() keeps a reference to the ops struct but not to the config struct (nor anything it contains). Document this. Signed-off-by:

The V4L2 flash interface allows controlling multiple LEDs through a single sub-devices if, and only if, these LEDs are of different types. This approach scales badly for flash controllers that drive multiple flash LEDs or for LED specific associations. Essentially, the original assumption of a LED driver chip that drives a single flash LED and an indicator LED is no longer valid. Address the matter by registering one sub-device per LED.

We are allocating memory for the v4l2 flash configuration structure and leak it in the normal path. Just use the stack for this as we do not use it outside of this function. Also use IS_ERR() instead of IS_ERR_OR_NULL() to check return value from v4l2_flash_init() for it never returns NULL. Fixes: 2870b52b ("greybus: lights: add lights implementation") Reported-by:

A debug printk statement was copied incorrectly into the new csi1 parser code and causes a warning there: drivers/media/platform/omap3isp/isp.c: In function 'isp_probe': include/linux/dynamic_debug.h:134:3: error: 'i' may be used uninitialized in this function [-Werror=maybe-uninitialized] Since there is only one lane, the index is never set. This changes the debug print to always print a zero instead, keeping the original format of the message.

Sphinx 1.6 generates some LaTeX code before each table, starting its own environment before calling tabulary, apparently to improve table layout. The problem is that such environment is incompatible with adjustbox. While, in thesis, it should be possible to override it or to redefine tabulary, I was unable to produce such patch. Also, that would likely break on some future Sphinx version. So, instead, let's just change the font size on bigger tables, in order for them to fit into the page size. That is not as good as adjustbox, and require some manual work, but it should be less sensitive to Sphinx changes. While here, adjust a few other tables whose text is exceeding the cell boundaries.

Update the Qualcomm Camera Subsystem driver document with a media controller pipeline graph diagram. Signed-off-by:
-
Todor Tomov authored
Use standard V4L2 control to get pixel clock rate from a sensor linked in the media controller pipeline. Then calculate clock rates on CSIPHY, CSID and VFE to use the lowest possible. If the currnet pixel clock rate of the sensor cannot be read then use the highest possible. This case covers also the CSID test generator usage. If VFE is already powered on by another pipeline, check that the current VFE clock rate is high enough for the new pipeline. If not return busy error code as VFE clock rate cannot be changed while VFE is running. Signed-off-by:

These files control the VFE module. The VFE has different input interfaces. The PIX input interface feeds the input data to an image processing pipeline. Three RDI input interfaces bypass the image processing pipeline. The VFE also contains the AXI bus interface which writes the output data to memory. RDI interfaces are supported in this version. PIX interface is not supported. Signed-off-by:

The calculation of the left volume looks suspect, the value of 0x1f - ((val << 8) & 0x1f) is always 0x1f. The debug prior to the assignment of value[1] prints the left volume setting using the calculation 0x1f - (val >> 8) & 0x1f which looks correct to me. Fix the left volume by using the correct expression as used in the debug.
