There is a hardware bug that the interrupt STMBUF_HALF may be triggered after or when disable interrupt. It may led to unexpected kernel panic. And interrupt STMBUF_HALF and STMBUF_RTND have no other effect. So disable them and the unused interrupts. meanwhile clear the interrupt status when disable interrupt. Signed-off-by:

In dynamic resolution change, streamoff and streamon on the capture queue may be called, the V4L2_DEC_CMD_STOP cmd may be called before driver parsed the jpeg header. don't clear the stop state in streamoff of handling the dynamic resolution change, otherwise the drain may not complete.

Quite often, the HW get stuck in error condition if a stream error was detected. As documented, the HW should stop immediately and self reset. There is likely a problem or a miss-understanding of the self reset mechanism, as unless we make a long pause, the next command will then report an error even if there is no error in it. Disabling error detection fixes the issue, and let the decoder continue after an error. This patch is safe for backport into older kernels.

Commit a1a2b712 ("of/platform: Drop static setup of IRQ resource from DT core") removed support for calling platform_get_resource(..., IORESOURCE_IRQ, ...) on DT-based drivers, but the probe() function of mtk-vcodec's encoder was still making use of it. This caused the encoder driver to fail probe. Since the platform_get_resource() call was only being used to check for the presence of the interrupt (its returned resource wasn't even used) and platform_get_irq() was already being used to get the IRQ, simply drop the use of platform_get_resource(IORESOURCE_IRQ) and handle the failure of platform_get_irq(), to get the driver probing again.

If allocating array_buf fails, or copying data from userspace into that buffer fails, then just free memory and return the error. Don't attempt to call video_put_user() since there is no point, and it would copy back data on error even if INFO_FL_ALWAYS_COPY wasn't set. So if writing the array back to userspace fails, then don't go to out_array_args, instead just continue with the regular code that just returns the error unless 'always_copy' is set. Update the VIDIOC_G/S/TRY_EXT_CTRLS ioctls to set the ALWAYS_COPY flag since they now need it. Before this worked due to this buggy code, but now that that is fixed these ioctls need to set this flag explicitly. Signed-off-by:

The driver does not expose controls directly and thus does not need a controls handler for its own use. Controls attached to subdevs used to be exposed that way, however this can easily lead to issue when multiple subdevs attached to the same v4l2 device expose the same controls. Subdev controls should be set through each individual subdev node instead. Signed-off-by:

Merge contents of structs sun6i_csi and sun6i_csi_dev into a main sun6i_csi_device structure holding a sun6i_csi_v4l2 struct for things related to v4l2, as well as the already-existing sun6i_csi_video and sun6i_csi_config which are left unchanged. This mostly simplifies accessing stuff by having a single main structure accessible to every part of the code instead of a private definition. Also solve some kerneldoc warnings by describing return codes while at it. No functional change is intended in this commit, variables are just moved around (cosmetics). Signed-off-by:
