Add V4L2 controls for analogue gain constants required to control analogue gain. The values are device specific and thus need to be obtained from the driver. Signed-off-by:

Drivers don't need to explicitly call devm_{}_put on driver removal, as it's automatically called by the device driver resource management code. Fixes: aab7ed1c ("media: i2c: Add driver for Aptina MT9V111") Signed-off-by:Ezequiel Garcia <ezequiel@collabora.com> Signed-off-by:

The OV8865 is a 8 Mpx CMOS image sensor producing 3264x2448 at 30 fps. Other modes (including some with sub-sampling) are available too. It outputs 10-bit bayer CFA data through a MIPI CSI-2 interface with up to 4 lanes supported. Some register initialisation sequences are still needed for this driver, as they cover registers for which no documentation is available. This work is based on the first version of the driver submitted by Kévin L'hôpital, which was adapted to mainline from the Allwinner BSP. This version is a rewrite of the first version that matches the structure of the OV5648 driver, with explicit PLL configuration, all the necessary mode-specific fields, associatied registers and reduced static sequences. It was tested with the Banana Pi Camera Board v3 and the Banana Pi M3. Co-developed-by:

The OV5648 is a 5 Mpx CMOS image sensor, connected via MIPI CSI-2 in a one or two lane configuration. Most of the features of the hardware are supported, including: - Auto and manual exposition/gain - Auto and manual white balance - Horizontal and vertical flip - Test patterns But the following are still missing: - Debanding, based on power source frequency; - Exposition setting correlated to time units.

The driver currently reports a single supported value for V4L2_CID_PIXEL_RATE and initializes the control's minimum value to 0, which is very risky, as userspace might accidentally use it as divider when calculating the time duration of a line. Fix this by using as minimum the only supported value when registering the control. Fixes: 5de35c9b ("media: i2c: Add Omnivision OV5670 5M sensor support") Signed-off-by:

According to the original code in the driver it was never assumed to work with big page sizes: unsigned short type followed by PAGE_SHIFT and PAGE_MASK which may be different on non-x86 architectures. Recently LKP found an issue on non-x86 architectures due to above mentioned limitations. Since Sakari acknowledges that it's not really useful to be able to compile this elsewhere, mark it x86 only. Fixes: a31d19f8 ("media: ipu3: allow building it with COMPILE_TEST on non-x86 archs") Reported-by:

kvmalloc() was used to allocate the temporary memory buffer that was used to contain both the IOCTL argument as well as a possible array argument that could have been large. Now that the two are separated, the IOCTL argument is known to be small in size. Use kmalloc to allocate it instead of kvmalloc. Similarly for releasing it. Suggested-by:

When an IOCTL with argument size larger than 128 that also used array arguments were handled, two memory allocations were made but alas, only the latter one of them was released. This happened because there was only a single local variable to hold such a temporary allocation. Fix this by adding separate variables to hold the pointers to the temporary allocations. Reported-by:

Add and document a media entity type for Image Signal Processor devices. Surprisingly we didn't have one, so add one now. More or less all ISP drivers should use this type instead of what they currently are using (or not using anything). Signed-off-by:
