Do not call dev_warn with a NULL device, this silence the following 2 warnings: [ 14.392194] (NULL device *): Failed to find gmin variable gmin_V2P8GPIO [ 14.392257] (NULL device *): Failed to find gmin variable gmin_V1P8GPIO We could switch to using pr_warn for dev == NULL instead, but as comments in the source indicate, the check for these 2 special gmin variables with a NULL device is a workaround for 2 specific evaluation boards, so completely silencing the missing warning for these actually is a good thing.

efivar_entry_get has certain alignment requirements and the atomisp platform code was not honoring these, causing an oops by triggering the WARN_ON in arch/x86/platform/efi/efi_64.c: virt_to_phys_or_null_size(). This commit fixes this by using the members of the efivar struct embedded in the efivar_entry struct we kzalloc as arguments to efivar_entry_get(), which is how all the other callers of efivar_entry_get() do this.

Between the ISP2400 and ISP2401 code base this function moved file. The merge of the drivers left us with two version in ifdefs. Resolve this down to a single copy. Signed-off-by:

ISP2401 introduced a rather sensible change to cut through the structure spaghetti. Adopt that for the ISP2400 as well. It makes no difference to the actual code other than readability. Signed-off-by:

The ISP2401 version of this function returns a pointer to the buffer, whilst the ISP2400 version returns a boolean if a slot is found. We can trivially unify the code to use the ISP2401 version. Signed-off-by:

The isp->inputs[] array has isp->input_cnt elements which have been initialized so this > should be >=. This bug is harmless. The check against ATOM_ISP_MAX_INPUTS prevents us from reading beyond the end of the array. The uninitialized elements are zeroed out so we will end up returning -EINVAL a few lines later because the .camera pointer is NULL. Signed-off-by:

If the mdp_* nodes are under an mdp sub-node, their corresponding platform device does not automatically get its iommu assigned properly. Fix this by moving the mdp component nodes up a level such that they are siblings of mdp and all other SoC subsystems. This also simplifies the device tree. Although it fixes iommu assignment issue, it also break compatibility with old device tree. So, the patch in driver is needed to iterate over sibling mdp device nodes, not child ones, to keep driver work properly. Signed-off-by:

Implement the V4L2_CID_MPEG_VIDEO_FORCE_KEY_FRAME control to force IDR frames. This is useful to implement VFU (Video Fast Update) on RTP transmissions. We already force an IDR frame at the beginning of each GOP to work around a firmware bug on i.MX27, use the same mechanism to service IDR requests from userspace. Signed-off-by:

The driver may sleep under a spin lock, and the function call path is: snd_cx18_pcm_hw_free (acquire the lock by spin_lock_irqsave) vfree --> may sleep To fix it, the "substream->runtime->dma_area" is passed to a temporary value, and mark it NULL when holding the lock.

The current driver has a handful of hard-coded assumptions based on its primary use for capture of video signals. Cleanup those assumptions, and also query the subdev for format information and use that if available. Tested with 10-bit raw bayer input (SGRBG10) using the aptina,mt9v032 sensor, and also tested that composite video input still works from ti,tvp514x decoder. Both tests done on the da850-evm board with the add-on UI board. NOTE: Will need further testing for other sensors with different bus formats. Signed-off-by:

Capture driver silently overrides pixel format with a hack (according to the comments) to pass v4l2 compliance tests. This isn't needed for normal functionality, and works for composite video and raw camera capture without. In addition, the hack assumes that it only supports raw capture with a single format (SBGGR8) which isn't true. VPIF can also capture 10- and 12-bit raw formats as well. Forthcoming patches will enable VPIF input with raw-camera support and has been tested with 10-bit format from the aptina,mt9v032 sensor. Any compliance failures should be fixed with a real fix.

The ir-spi driver has 2 issues which prevents it from working with lirc: 1. The ir-spi driver uses 16 bits of SPI data to create one cycle of the waveform. As such our SPI clock needs to be 16x faster than the carrier frequency. The driver is inconsistent in how it currently handles this. It initializes it to the carrier frequency: But the commit message has some example code which initialises it to 16x the carrier frequency: val = 608000; ret = ioctl(fd, LIRC_SET_SEND_CARRIER, &val); To maintain compatibility with lirc, always do the frequency adjustment in the driver. 2. lirc presents pulses in microseconds, but the ir-spi driver treats them as cycles of the carrier. Similar to other lirc drivers, do the conversion with DIV_ROUND_CLOSEST(). Fixes: fe052da4 ("[media] rc: add support for IR LEDs driven through SPI") Cc: stable@vger.kernel.org Signed-off-by:

interrupts is listed as an optional property in the DT binding, but in reality the driver didn't work without it. The existing driver relied on having the interrupt line connected to the SoC to trigger handling various events. Add the option to poll the interrupt status register via a timer if no interrupt source is defined. Signed-off-by:
