MWB gain register are used to set gain for each mwb channel mannually. However, it will involve some artifacts at low light environment as gain cannot be applied to each channel synchronously. Update the driver to use group write for digital gain to make the sure RGB digital gain be applied together at frame boundary. Signed-off-by:

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Wrap the target region in struct_group(). This additionally fixes a theoretical misalignment of the copy (since the size of "buf" changes between 64-bit and 32-bit, but this is likely never built for 64-bit). FWIW, I think this code is totally broken on 64-bit (which appears to not be a "real" build configuration): it would either always fail (with an uninitialized data->buf_size) or would cause corruption in userspace due to the copy_to_user() in the call path against an uninitialized data->buf value: omap3isp_stat_request_statistics_time32(...) struct omap3isp_stat_data data64; ... omap3isp_stat_request_statistics(stat, &data64); int omap3isp_stat_request_statistics(struct ispstat *stat, struct omap3isp_stat_data *data) ... buf = isp_stat_buf_get(stat, data); static struct ispstat_buffer *isp_stat_buf_get(struct ispstat *stat, struct omap3isp_stat_data *data) ... if (buf->buf_size > data->buf_size) { ... return ERR_PTR(-EINVAL); } ... rval = copy_to_user(data->buf, buf->virt_addr, buf->buf_size); Regardless, additionally initialize data64 to be zero-filled to avoid undefined behavior.

The media bus configuration is specified through a set of flags, some of which being mutually exclusive. This doesn't scale to express more complex configurations. Improve the API by replacing the single flags field in v4l2_mbus_config by a union of v4l2_mbus_config_* structures. The flags themselves are still used in those structures, so they are kept here. Drivers are however updated to use structure fields instead of flags when already possible. Signed-off-by:

The vimc driver is used for testing purpose, and some test use cases involve sharing buffers with a consumer device. Consumers often require DMA contiguous memory, which vimc doesn't currently support. This leads in the best case to usage of bounce buffers, which is very slow, and in the worst case in a complete failure. Add support for the dma-contig allocator in vimc to support those use cases properly. The allocator is selected through a new "allocator" module parameter, which defaults to vmalloc.

So, change the logic which checks if dummy_ptr was allocated. At this point, atomisp now gives WARN_ON() in hmm_free() [2] on atomisp reload by rmmod/insmod. Again, the check is wrong there. So, change both checks for mmgr_EXCEPTION, which is the error value when HMM allocation fails, and initialize dummy_ptr with such value.

The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on after having turned it off causes the CPLM3218 ambient-light-sensor on the front camera sensor's I2C bus to crash, hanging the bus. Add a DMI quirk table for systems on which to leave eldo2 on. Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor as long as the camera sensor is being used, this is what Windows seems to do as a workaround (based on analyzing the DSDT). But that is not easy to do cleanly under Linux. Link: https://lore.kernel.org/linux-media/20220116215204.307649-10-hdegoede@redhat.comSigned-off-by:

On devices with 2 cameras and no _DSM / EFI-vars providing CsiPort clock info, defaulting to CsiPort 0 obviously is wrong for 1 of the 2 cameras. The Intel Cherry Trail (ISP2401) reference design combines: pmc_plt_clk_2 with CsiPort 0 pmc_plt_clk_4 with CsiPort 1 The Intel Bay Trail (ISP2400) reference design combines: pmc_plt_clk_1 with CsiPort 0 pmc_plt_clk_0 with CsiPort 1 Use this knowledge to set the default CsiPort value based on the detected CLK for the sensor.

Testing on multiple tablet models has shown that Android always uses 1.6V for ELDO1, adjust our code to match. This also matches with how ELDO1 is used in the DSDTs on these devices, where for Cherry Trail (ISP2401) based devices ELDO1 is used for an ACPI power-resource which is named "P16P". Note on Bay Trail (ISP2400) based devices the power-resource is called "P15P", which suggests that 1.5V might be a better value there.

On devices with 2 sensors the 2 sensors may get probed simultaneously and the v1p8 and v2p8 regulators are ususally shared between the 2 sensors. This means that the probe() function of sensor 1 may end up calling gmin_v1p8_ctrl(..., false) turning the regulator off while sensor 2's probe() function still needs it to be on, causing the probe() of sensor 2 to sometimes fail. Fix this by adding an enable-count for both regulators and only disabling them again when that goes to 0. Note all this really should be converted to use the standard kernel regulator framework, I have doing this on my long term TODO list, this fix is only meant as a temporary workaround for the issue.
