2008-10-12V4L/DVB (8906): v4l-dvb: fix assorted sparse warningsHans Verkuil
Fix sparse warnings. None are serious, but cutting down on these helps find future serious sparse warnings/errors. Redid the av7710.c patch based on a suggestion by Oliver Endriss. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-10-12V4L/DVB (8901): pvrusb2: Disable virtual IR device when not needed.Mike Isely
Disable "virtual" IR receiver on for 24xxx devices that have an internal IR blaster. In that case there's another another IR receiver present and to leave the virtual receiver available just causes confusion. This means that 24xxx users will no longer see a phantom IR chip.

2008-10-12V4L/DVB (8900): pvrusb2: Implement cropping pass throughMike Isely
This builds upon the previous pvrusb2 change to more formally implement full cropping support. This enables access from the driver's V4L interface, and enables access to full capabilities from sysfs as well. Note that this is only effective when in analog mode. It also will only work when the underlying digitizer's driver (saa7115 or cx25840 depending on the hardware) also implements the appropriate functions.

2008-10-12V4L/DVB (8895): pvrusb2: Fail gracefully if an alien USB ID is usedMike Isely
The driver includes an internal table specifying additional information on a per device-type basis. This works great until somebody tries to run-time associate another USB ID with the driver. This change should hopefully allow the driver to fail gracefully under such a circumstance. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-10-12V4L/DVB (8894): pvrusb2: Remove BKLMike Isely
The earlier change from Hans Verkuil that pushed the BKL from video_open() down into the drivers should be unneeded for the pvrusb2 driver. This driver's implementation for open already protects its internal structures through other means, thus the BKL is not required. This change reverses Hans' previous change, for the pvrusb2 driver. It probably would have been a good idea for Hans to previously have asked for my ack before committing his change.

2008-10-12V4L/DVB (8613): v4l: move BKL down to the driver level.Hans Verkuil
The BKL is now moved from the video_open function in v4l2-dev.c to the various drivers. It seems about a third of the drivers already has a lock of some sort protecting the open(), another third uses video_exclusive_open (yuck!) and the last third required adding the BKL in their open function.

The device 2040:2950 is a really old variant of the PVR USB2 hardware. I have just learned of its existence. For the purposes of the pvrusb2 driver, it is functionally identical to the well known 29xxx series (2040:2900). Amazing that this went undetected for 3+ years.

2008-07-24PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi
On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.

2008-07-20V4L/DVB (7939): pvrusb2: Remove sysfs interface hackeryMike Isely
Back in the early days of the pvrusb2 driver, the kernel class mechanism in use for the sysfs interface had no means to pass per-attribute information to the show / store functions. This forced me to implement a horrible ugly thunking mechanism (i.e. infer the missing data through the use of dedicated cookie cutter bounce functions). However now we're using a better mechanism which also passes enough additional information to the show / store functions that we no longer need the hack. So eliminate all the crap. Yay!

2008-07-20V4L/DVB (7938): pvrusb2: Increase enforced encoder wait delay to improve ↵Mike Isely
reliability The driver enforces a "quiet period" on the encoder in certain situations before attempting to operate it. This seems to help avoid video encoding errors / corruption.

2008-07-20V4L/DVB (7883): pvrusb2: make default frequency configurable via modprobe optionMichael Krufky
The pvrusb2 driver initially sets the tuner to known broadcast frequencies in the Chicago area, to ease driver testing for the maintainer. This patch keeps those default frequencies, but allows them to be altered via modprobe option. This allows the same ease and convenience for testing multiple pvrusb2 devices one after another under other conditions and areas. For instance, the default initial frequency, 175.25 MHz, might not necessarily be valid on all cable television networks, but usually will be a valid NTSC broadcast channel.

2008-05-14V4L/DVB (7851): Fix FW_LOADER depencency at v4l/dvbMauro Carvalho Chehab
Since: 1) FW_LOADER is defined as: config FW_LOADER tristate "Userspace firmware loading support" depends on HOTPLUG 2) several V4L/DVB driver just selects it; 3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER. So, All drivers that select FW_LOADER should also depend on HOTPLUG. An easier solution (for the end-user perspective) would be to "select HOTPLUG". However, live is not simple. This would cause recursive dependency issues like this one: drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD -> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA -> USB_ARCH_HAS_HCD -> MOUSE_APPLETOUCH -> USB Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
