2008-09-04cx18: Increment u8 pointers not void pointers.Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Increment u8 pointers not void pointers. Incrementing void pointers is dubious and the real intent in cx18_memcpy_fromio() and cx18_memset_io() is to increment by bytes, so use u8 pointers instead. Priority: high Signed-off-by: Andy Walls <awalls@radix.net>
2008-08-31cx18: Throttle mmio to/from the CX23418 so boards work in older systemsAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Throttle mmio to/from the CX23418 so boards work in older systems. The CX23418 couldn't reliably handle mmio at the rate at which the cx18 driver was attempting to access the chip. The PCI bridge arrangements and settings on modern motherboards still allowed the CX23418 to work OK, but it didn't work well on many older motherboards: mysterious I2C errors, firmware loading errors, etc. This patch adds a throttle to *all* mmio access to the CX23418. It defaults to a delay of 31 ns, but is adjustable by the mmio_ndelay module parm. My HVR-1600 and Raptor PAL/SECAM card now function for analog capture on a motherboard with an Intel 82810E Northbridge and 82801AA Southbridge.

From: Andy Walls <awalls@radix.net> cx18: Create cx18_ specific wrappers for all pci mmio accessesors. This is a first step in instrumenting all CX23418 PCI bus IO, to debug problems with accessing the CX23418's PCI memory mapped IO. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2008-08-29cx18: Correct CX23418 PCI configuration settings.Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Correct CX23418 PCI configuration settings. The CX23418 doesn't have I/O space registers, so there was no need to try and turn them on (the card ignores the attempt to set the bit anyway). Also removed incorrect config space register setting that was errantly borrowed from ivtv. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2008-08-23cx18: Have CX23418 release buffers at end of capture.Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Have CX23418 release buffers at end of capture. The CX23418 reuses task handles so we need to have it release the buffers associated with a task handle at the end of a capture. If we don't, buffer ids used for one type of stream in the driver (MPEG, TS, PCM), could be used for another type of stream by the CX23418, if a previously used handle is assigned to a different type of stream. The driver would drop valid buffers when this happened. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2008-08-23cx18: Fix cx18_find_handle() and add error checkingAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Fix cx18_find_handle() and add error checking. cx18_find_handle() did not find a good task handle and would use the invalid task handle under common conditions. Added a define for the invalid task handle and added error checking as well. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2008-08-22cx18: Convert cx18_queue buffers member to atomic_tAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Convert cx18_queue buffers member to atomic_t. This allows safe concurrent access to check if a queue has data without having to acquire the queue spinlock. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>

2008-08-22cx18: Simplify queue flush logic to prevent oops in cx18_flush_queues()Andy Walls
From: Andy Walls <awalls@radix.net> cx18: Simplify queue flush logic to prevent oops in cx18_flush_queues(). If accounting of a queue is in error, logic borrowed from ivtv will cause an oops when flushing the queues for a stream. This change greatly simplifies the queue flush logic, and sets the queue back to sane defaults on a flush. Priority: high Signed-off-by: Andy Walls <awalls@radix.net>

2008-08-20V4L1: make PMS not autoprobe when builtin.Mauro Carvalho Chehab
From: Rene Herman <rene.herman@keyaccess.nl> The old Mediavision Pro Movie Studio legacy ISA V4L1 driver was found to hang the boot during Ingo Molnar's testing of randconfig kernels. Have it require a "pms.enable=1" kernel parameter to enable the driver when builtin which avoids such problems. This is a deprecated and, very likely, unused driver. Nothing changes modular behaviour moreover.

From: Simon Arlott <simon@fire.lp0.eu> If saa7134_init is run before v4l2_i2c_drv_init (tuner), then saa7134_board_init2 will try to set the tuner type for devices that don't exist yet. This moves tuner to before all of the device-specific drivers so that it's loaded early enough on boot.

From: Felipe Balbi <felipe.balbi@nokia.com> This driver sure needs some rework. For now, let's try to clean it up a bit before start reimplementing anything. checkpatch.pl still not happy with this driver after this patch, but the most annoying errors are gone, comments now use C-style only, labels are well placed and some other minor fixes. Some more clean up patches will come as I work on this driver. Please review it carefully.

From: Hans de Goede <j.w.r.degoede@hhs.nl> This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags, and sets this flag for the Philips SPC200NC cam (which has its sensor installed upside down). The same flag is also needed and added for the Philips SPC300NC. Together with a patch to libv4l which adds flipping the image in software this fixes the upside down display with the SPC200NC cam.
