The refactoring of the cx25840 driver to support the cx23888 caused breakage with the existing support for cx23885/cx23887 analog support. Rework the routines such that the new code is only used for the 888. Validated with the following boards: HVR-1800 retail (0070:7801) HVR-1800 OEM (0070:7809) HVR_1850 retail (0070:8541) Thanks to Steven Toth and Hauppauge for loaning me various boards to regression test with.

Commit 7a6f6c29 (cx231xx: use URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer for URB twice. This works for the URBs allocated with usb_alloc_urb(), as those are allocated from cohernent DMA pools, but the flag was also added for the VBI and audio URBs, which have a manually allocated area. This leaves the random trash in the structure after allocation as the DMA address, corrupting memory and preventing VBI and audio from working. Letting the USB core map the buffers solves the problem. Cc: stable@kernel.org Signed-off-by:

The driver is supposed to create active media link from sensor N (or its corresponding s5p-mipi-csis entity) to FIMC.N by default. Instead s5p-mipi-csis.N entity gets always connected by a default active link to FIMC.N, regardless of there are parallel bus sensor entities already connected to FIMC.N. Correct this. Signed-off-by:

When video pipeline initialization fails, the ST_CAPT_BUSY flag needs to be cleared before pm_runtime_put_sync is called. Otherwise the runtime suspend routine tries to suspend device, rather than just turning it off. Also fix potential null pointer dereference in fimc_pipeline_shutdown(). Signed-off-by:

Fix the documentation of the Y4 and Y6 formats. Fix a poll() issue, add support for enum_frmsizes, set the proper parent device and fix a few compliance issues. Tested with an actual Connectix B&W parallel port webcam, both on a little-endian and a big-endian platform. This driver has never been so good, doing 320x240 at 1 frame per second :-) I know, nobody cares, but still it is cool that linux can still support this old webcam. Signed-off-by:
