2008-03-16tda827x: fixed support of tuners with LNAHartmut Hackmann
From: Hartmut Hackmann <hartmut.hackmann@t-online.de> Tuner refactoring broke support of tuners with LNA configurations 1 and 2 for both, analog TV and DVB-T. Additionally, this patch initializes the saa713x gpios defined by the gpiomask at driver init to avoid undefined stated at dvb. Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de>

Subject: Convert videobuf-dma-sg to generic DMA API Date: Tue, 19 Feb 2008 13:40:54 +0100 (CET) videobuf-dma-sg does not need to depend on PCI. Switch it to using generic DMA API, convert all affected drivers, relax Kconfig restriction, improve compile-time type checking, fix some Coding Style violations while at it.

2007-12-11Add EXPORT_SYMBOL_GPL to the saa7134 video control routinesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Those newer functions are used by saa7134-empress. Adds export for them: +EXPORT_SYMBOL_GPL(saa7134_g_ctrl); +EXPORT_SYMBOL_GPL(saa7134_s_ctrl); +EXPORT_SYMBOL_GPL(saa7134_queryctrl); Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-12-11Convert saa7134-empress to video_ioctl2Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> saa7134 were converted to video_ioctl2, but saa7134_empress weren't. This broke saa7134-empress, since it were dependent of saa7134_common_ioctl. With the conversion, the module had a size decrease of 436 bytes on x86_64: text data bss dec hex filename 5196 4912 4 10112 2780 old/saa7134-empress.ko 4760 4912 4 9676 25cc new/saa7134-empress.ko Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-12-11Fix VBI supportMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> VBI were broken, since there weren't any function handlers for it. This patch fixes it, by removing the vbi_template, using, instead video_template. This also saves some extra BSS data. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-18Replace TDA9887_SET_CONFIG by TUNER_SET_CONFIGMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Currently, the only tuner-specific device that allows special configurations is tda9887. However, tea5767 also may require some special configurations (for example, to specify a different Xtal freq). This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl (TUNER_SET_CONFIG). The newer one allows specifying what tuner is appliable to a configuration set, and allows an arbitrary configuration struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-12 Additional Fixes for saa7134 suspend/resumeMauro Carvalho Chehab
From: Maxim Levitsky <maximlevitsky@gmail.com> Fixes few more problems I found in my saa7134 resume code: * Race between IRQ handler and .suspend()/.resume() functions * Removes timeout timers on active buffers - those buffers will be recaptured after resume * Adds suspend/resume for IR code - probably necessary if using polling mode * Adds #ifdef CONFIG_PM overs suspend code * Runs a quirk in set_tvnorm in suspend/resume too * Rearranges the order of calls in saa7134_resume to be exactly as in saa7134_initdev thus the card is initialized in exactly the same way * Since DMA audio capture suspend/resume isn't yet supported, avoid re-enabling it on resume for now Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-15v4l core: remove the unused .hardware V4L1 fieldMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> struct video_device used to define a .hardware field. While initialized on severl drivers, this field is never used inside V4L. However, drivers using it need to include the old V4L1 header. This seems to cause compilation troubles with some random configs. Better just to remove it from all drivers.

2007-10-10saa7134: Replace list_for_each+list_entry with list_for_each_entryTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> A couple loops weren't changed because they expected the loop iterator to be left as NULL if the list was empty. Maybe the code should just check for that first, then loop? Adjust some of the loop logic to be simpler. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2007-09-27V4L: properly fix support for capturing interlaced video in saa7134Maxim Levitsky

2007-08-23Adapt drivers to use the newer videobuf modulesMauro Carvalho Chehab
PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo. Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct. So, to access it, a subroutine call is needed. This patch renames all occurences of those function calls to be consistent with the video-buf split.

2007-07-02Fix v4l-dvb backward compatibilityMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Due to several internal API changes on kernel, kernel backward compatibility were lost. Basically, compat.h should be the last include for it to work properly. This patch basically reorders kernel headers to allow backward compat to work fine. Also: Some includes were added after some non-include macros, on old drivers. Better to keep all includes at the beginning of the files. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-03-17Fixed no_overlay option and quirks on saa7134 driverMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Some chipsets have several problems when pci to pci transfers are activated on overlay mode. the option no_overlay allows disabling such feature of the driver, in favor of keeping the system stable. The default is to use pcipci_fail flag defined on drivers/pci/quirks.c. It also allows the user to override it by forcing disable overlay or forcing enable. Forcing enable may generate PCI transfer corruption, including disk mass corruption, so should be used with care. Added a text description to this option and make messages looks the same at both bttv and saa7134 drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

It is still DMA centric, although it may be used also by devices that emulates scatter/gather behavior or a DMA device Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2005-11-09Moves 32 bit ioctl compat handler to V4L sybsystemMauro Carvalho Chehab
From: Arnd Bergmann <arnd@arndb.de> This moves the 32 bit ioctl compatibility handlers for Video4Linux into a new file and adds explicit calls to them to each v4l device driver. Unfortunately, there does not seem to be any code handling the v4l2 ioctls, so quite often the code goes through two separate conversions, first from 32 bit v4l to 64 bit v4l, and from there to 64 bit v4l2. My patch does not change that, so there is still much room for improvement. Also, some drivers have additional ioctl numbers, for which the conversion should be handled internally to that driver.
