Simplify the way outgoing work handler gets scheduled to send empty buffers back to the firmware for use. Also reduced the memory required for scheduling this outgoing work, by using a single, per stream work object.

This change defers sending all CX18_CPU_DE_SET_MDL commands, for a stream with an ongoing capture, by adding a work queue to handle sending such commands when needed. This prevents any sleeps, caused by notifying the firmware of new usable buffers, when a V4L2 application read() is being satisfied or when an incoming buffer is processed by the cx18-NN-in work queue thread.

Rename the work queue to "in_work_queue" to indicate it is handling incoming mailbox commands. This is preparation for adding a work queue for handling deferrable outgoing mailbox commands. Signed-off-by: NAndy Walls <awalls@radix.net> Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

The init callback was used in several places to load firmware. Make a separate load_fw callback for that. This makes the code a lot more understandable. Signed-off-by: NHans Verkuil <hverkuil@xs4all.nl> Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

Convert GPIO line functions, such a audio routing and device resets, to v4l2_subdevices. This essentially completes the conversion of cx18 to the v4l2_device/v4l2_subdevice framework. No regression testing has taken place as of yet. Also an ivtv legacy bug with GPIO mux routing and going to/from radio mode was commented, but not fixed.

Added a new chip identifer to v4l2-chip-ident for the integrated A/V broadcast decoder core internal to the CX23418. Completed separation and encapsulation of the A/V decoder core interface as a v4l2_subdevice. The cx18 driver now compiles and links again.

Sliced VBI, in the manner that ivtv implements it as a separate data stream, now works for 525 line 60 Hz systems like NTSC-M. It may work for 625 line 50 Hz systems, but I have more engineering work to do, to verify it is operating properly. Sliced data insertion into the MPEG PS should be working, but is untested.

The cx23418 appears to send Raw VBI buffers with a PTS on a per frame basis, not per field, so process Raw VBI on a whole frame basis and reduce some complexity. Fix VBI buffer size computation to handle a whole frame of Raw VBI for a 625 line system, which is the worst case and will work for 525 lines systems as well.

This is a port of the fixes Hans Verkuil made for ivtv/cx25840: The service_set field was used to determine whether raw or sliced VBI was desired. This is incorrect since it is perfectly valid to select sliced VBI with a service_set of 0. Instead the driver should check on VIDIOC_S_FMT whether the type field matches the raw or sliced VBI type. Updated the cx18 driver accordingly, including an additional check in cx18_start_v4l2_encode_stream() that didn't exist in ivtv.

A major rewrite of interrupt handling for incoming mailbox processing, to split the timing critical steps from the the deferrable steps as the sending XPU on the CX23418 will time out and overwrite our incoming mailboxes rather quickly. Setup a pool of work "order forms" for the irq handler to send jobs to the new work handler routine which uses the kernel default work queue to do the deferrable work. Started optimizing some of the cx18-io calls as they are now the low hanging fruit for recoving microseconds back from the timeline. Future optimizations will get rid of mmio read retries, mmio stats logging, and combine smaller functions in the irq path into the larger ones to save ~2 us each.
