2007-04-27V4L/DVB (5329): Some saa7134 cleanupsHeikki Orsila
- use generic sort instead of bubblesort - removed useless saa7134_video_fini function - small coding style changes Signed-off-by: Heikki Orsila <heikki.orsila@iki.fi> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5326): Allow to set tuner_config in attach informHartmut Hackmann
This patch move the assignment of the tuner config and the callback before the check whether it is called in the attach inform. This solves a module load order issue Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5324): This patch fixes request_module_depend()Markus Rechberger

2007-04-27V4L/DVB (5323): Updated support for tuner callbacksHartmut Hackmann
This change supplies a more generic version of the tuner callback. The tuner struct now has a function pointer int (*tuner_callback) (void *dev, int command, int arg) additionally to a int config parameter. both can be set through the TUNER_SET_TYPE_ADDR client call. Note that the meaning of the parameters depend on the tuner type. Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5322): Removed board naming code in saa7134-dvbHartmut Hackmann
This is for better consistency with other drivers Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5321): Saa7134-dvb: initialize the dvb frontend in dvb_initHartmut Hackmann
The hardware is completely initialized afterwards, especially the tda10046 has its firmware - which is also necessary in analog mode of some hybrid boards. Calling the sleep function afterwards saves power and definitely puts hybrid boards into analog mode without additional code elsewere.

2007-04-27V4L/DVB (5320): Filled in limiting values in tda827x.cHartmut Hackmann

2007-04-27V4L/DVB (5319): Set tda827x to sleep mode after attachHartmut Hackmann
This change sets the tda827x to sleep mode right after attach in dvb mode. It is just to save power. For the same reason, the ADC of the tda10046 gets turned off in sleep mode.

2007-04-27V4L/DVB (5318): Fix tda8290 code for tda827x moduleHartmut Hackmann
During tuner attach, the pointers to host dev structure are not set yet, so the I2c adapter needs to be accessed differently. This patch also does some minor cleanup in the saa7134-dvb module.

2007-04-27V4L/DVB (5315): Tda1004x: check request firmware for NULL ponter againHartmut Hackmann
In older versions, this was used to decide whether to boot from eeprom or file. This is no longer necessary but the check helps to avoid an oops with misconfigured cards. Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5314): Added support for tda827x tuners with preamlifiersHartmut Hackmann
This patch contains - new tuning code for the tda827xa silicon tuner. - controls the preamplifier of some boards with this tuner. - support for the Philips Tiger S hybrid DVB-T reference design. - reworked the saa7134-dvb modulue to get rid of most of the small board specific functions.

2007-04-27V4L/DVB (5313): Added a config entry and a gpio function pointer to tuner structHartmut Hackmann
These entries mainly are to support configurations of the tda827x silicon tuner with a preamplifier. The values can be set throgh the attach inform or through the extended TUNER_SET_TYPE_ADDR client call. The function pointer will only be updated if the parameter is not NULL. Since a typecast is necessary to set the pointer, i added a typedef for this pointer (tuner_gpio_func_t) in tuner.h Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5312): Saa713x: added a GPIO handler functionHartmut Hackmann

2007-04-27V4L/DVB (5311): Tda1004x driver updatesHartmut Hackmann
There are the following changes: - separate configuration of IF and GPIOs. - set GPIOs before firmware load. This helps to avoid I2C address collisions. - if desired invert GPIOs at sleep (automatic return to analog mode of card). - added 3 tuner configuration bytes to config stuct. - added i2c gate address to config struct. - moved _state struct declaration to header file to make it accessible on board layer. - added "conf_probed" to the state struct to allow i.e. probing for correct tuner version. - changed firmware load mechanism to always: + check if already loaded + try to boot from eeprom + try downlad from host - corrected name of tda10046 firmware image (backward compatible).

2007-04-27V4L/DVB (5307): Add support for the cx23415 MPEG decoding features.Hans Verkuil

2007-04-27V4L/DVB (5306): Add support for VIDIOC_G_CHIP_IDENTHans Verkuil
VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be used to detect which chips are on the board and based on that information selected register dumps can be made, making it easy to debug complicated media chips containing tens or hundreds of registers. This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-04-27V4L/DVB (5290): Add support for VIDIOC_INT_G/S_STD_OUTPUTHans Verkuil
Added VIDIOC_INT_G_STD_OUTPUT and VIDIOC_INT_S_STD_OUTPUT to allow drivers to set the TV standard for video output separately from the video capture. This is needed for cx23415 support where the decoder is separate from the encoder and can have a different TV standard. Modified the saa7127 module to listen to VIDIOC_INT_G/S_STD_OUTPUT instead of VIDIOC_G/S_STD.
