2022-05-13media: atmel: atmel-isc-base: use mutex to lock awb workq from streamingEugen Hristev2-4/+28
The AWB workqueue runs in a kernel thread and needs to be synchronized w.r.t. the streaming status. It is possible that streaming is stopped while the AWB workq is running. In this case it is likely that the check for vb2_start_streaming_called is done at one point in time, but the AWB computations are done later, including a call to isc_update_profile, which requires streaming to be started. Thus , isc_update_profile will fail if during this operation sequence the streaming was stopped. To solve this issue, a mutex is added, that will serialize the awb work and streaming stopping, with the mention that either streaming is stopped completely including termination of the last frame is done, and after that the AWB work can check stream status and stop; either first AWB work is completed and after that the streaming can stop correctly. The awb spin lock cannot be used since this spinlock is taken in the same context and using it in the stop streaming will result in a recursion BUG.

2022-05-13media: atmel: atmel-isc-base: use streaming status when queueing buffersEugen Hristev1-1/+1
During experiments with libcamera, it looks like vb2_is_streaming returns true before our start streaming is called. Order of operations is streamon -> queue -> start_streaming ISC would have started the DMA immediately when a buffer is being added to the vbqueue if the queue is streaming. It is more safe to start the DMA after the start streaming of the driver is called. Thus, even if vb2queue is streaming, add the buffer to the dma queue of the driver instead of actually starting the DMA process, if the start streaming has not been called yet. Tho achieve this, we have to use vb2_start_streaming_called instead of vb2_is_streaming.

2022-05-13media: vsp1: Fix offset calculation for plane croppingMichael Rodin1-3/+3
The vertical subsampling factor is currently not considered in the offset calculation for plane cropping done in rpf_configure_partition. This causes a distortion (shift of the color plane) when formats with the vsub factor larger than 1 are used (e.g. NV12, see vsp1_video_formats in vsp1_pipe.c). This commit considers vsub factor for all planes except plane 0 (luminance). Drop generalization of the offset calculation to reduce the binary size.

The mipi_csis_device.powered flag only serves for the purpose of not accessing registers in mipi_csis_log_status() when the interface is not powered up. Instead of manually tracking the power state, rely on pm_runtime_get_if_in_use() to remove the 'powered' flag. Also remove the locking in the function as runtime_pm() is refcounted and there's no risk of the interface being powered down behind our backs.

Simplify the mipi_csis_s_stream() function. This actually fixes a bug, as if calling the subdev's s_stream(1) fails, mipi_csis_stop_stream() was not called.

2022-04-24media: imx: imx-mipi-csis: Simplify runtime PM implementationLaurent Pinchart1-21/+17
The runtime PM resume handler is guaranteed to be called on a suspended device, and the suspend handler on a resumed device. The implementation can thus be simplified. While at it, rename the mipi_csis_device state field to powered, as the now state contains a single flag only.
