2008-02-08Allow more than one em28xx boardMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> em28xx driver is capable of handling more than one usb device. However, isoc transfers require a large amount of data to be transfered. Before this patch, just one em28xx board were enough to allocate more than 50% URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=480/800 us (60%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, only one board could use an USB host at the same time. After the patch, it is possible to use more than one em28xx at the same time, on the same usb host, if the image size is slower or equal to 345600, since those images will require about 30% of the URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=232/800 us (29%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, in thesis, after the patch, it would be possible to use up to 3 boards by each usb host, if the devices are generating small images.

2008-01-28 em28xx/: make 2 functions staticMauro Carvalho Chehab
From: Adrian Bunk <bunk@kernel.org> This patch makes the following needlessly global functions static: - em28xx-core.c:em28xx_write_reg_bits() - em28xx-video.c:em28xx_vdev_init() Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-01-24em28xx: remove has_tunerMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> has_tuner flag doesn't make much sense, since tuner_type=TUNER_ABSENT means the same thing. Having two ways to say that a tuner is not present is not nice, since it may lead to bad setups. In fact, with the previous code, if a device were using has_tuner=0, but the user forces a tuner, with modprobe option tuner=type, the modprobe option won't work. Also, tveeprom returns TUNER_ABSENT, when tuner is unknown or absent. So, with the previous logic, in this case, the driver should set has_tuner=0, or has_tuner=1 otherwise. Instead of adding several additional tests and setups, better just to remove .has_tuner. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-01-13Move all board specific configuration to em28xx-cards.cMauro Carvalho Chehab

2008-01-05Add code for autoloading em28xx-alsa, if neededMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Older em28xx devices does implement standard Audio Class. However, on newer devices, this were replaced by a Vendor Class. This patch autodetects that an em28xx lacks Audio Class and auto-loads em28xx-alsa, for the devices that implements only a Vendor Class. For devices with Audio Class, snd-usb-audio module will provide an ALSA interface. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-01-05HVR950 requires additional settings for audio to properly workMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Thanks to Markus Rechberger <mrechberger@gmail.com> for retriving those commands. Also, MTS firmware is required for audio to work on HVR950. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-01-05Improve audio setup handlingMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> It is possible to select audio inputs via em28xx or via ac97 functions. This patch allows configuring a board to use either one way. It also do some cleanups at audio setup configurations. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-11-22Convert MTS to bitfieldMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Xc2028.3028 has two type of firmwares: audio-standard specific ones and baseband MTS firmwares. MTS firmwares provide stereo decoding for 6 MHz BTSC/EIAJ and for monoaural audio decoding on 8 MHz firmwares. It seems that the option to use MTS or a standard-specific audio decoding depends on the way xc2028/3028 is connected. Instead of wasting 32 (or 64 bits) to signalize if the driver needs to use MTS firmware, this patch converts it to a bitfield that can be shared with other proprieties of xc2028/3028.

2007-11-20Use MTS firmware for the HVR-900Mauro Carvalho Chehab
From: Aidan Thornton <makosoft@googlemail.com> The HVR-900 requires the MTS version of the xc3028 firmware in order to get any sound. The below patch selects this firmware variant on HVR-900 cards, as well as splitting the HVR-950 into its own entry (since I don't know if it uses the MTS variant and it will have to be split off eventually anyway).

2007-11-11Cleanup at tv norm selectionMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> With the conversion to the vidio_ioctl2, tvnorms array is not required anymore. Also, removed some code from V4L1 time (VIDEO_MODE_foo), specied at the non-used video_decoder.h. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-11-11Remove some dead code and make drive fully V4L2 compatibleMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> There were some vestiges of an old V4L1 I2C driver that were called by em28xx. This patch removes this dead code, and replaces videodev.h to videodev2.h Now, this driver doesn't require V4L1 anymore. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-11-10Fix em28xx to allow multiple openMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Allows shared access support for em28xx. Just one userspace application is allowed to get stream. The other(s) application(s) can change V4L2 controls, set video standards, etc. This patch were splited from Markus Rechberger's tree and backported to 2.6.17 by Pádraig Brady. The original patch were ported to the latest em28xx version and had CodingStyle corrected to solve the issues pointed by scripts/checkpatch.pl.

2007-11-04em28xx: autodetect Cinergy 200 USB and VGear PocketTVMauro Carvalho Chehab
From: Sascha Sommer <saschasommer@freenet.de> Adds autodetection support for the Cinergy200 USB and the VGear PocketTV. Whenever a usb device with generic empia em2800 usb ids is detected the device gets scanned for connected i2c devices. If the device list matches an em2800 device in the device list the model id gets changed accordingly.

2007-11-03 em28xx: add support for vgear pockettvMauro Carvalho Chehab
From: Sascha Sommer <saschasommer@freenet.de> attached patch adds support for the vgear pockettv. It seems to require a write to another register for audio to work. I checked my old cinergydrv and we did the same register write there. I therefore enabled it for all em2800 based devices.

2007-11-03em28xx: fix locking to allow accesses from 2 different threads at the same timeMauro Carvalho Chehab
From: Sascha Sommer <saschasommer@freenet.de> The attached patch modifies the em28xx driver so that there can be ioctls from multiple different threads. This is necessary for capture apps like MPlayer that use different threads for capturing and channel tuning. Now the locking is only done for the ioctls that change properties of the device or access the i2c bus. It also removes some locks that look unnecessary: In em28xx_init_dev: the videodevice is not registered yet so nothing can access the hardware meanwhile, the device struct is not assigned to the interface yet so no race with disconnect is possible In em28xx_release_resources: it gets only called when dev->lock is already held Signed-off-by: Sascha Sommer <saschasommer@freenet.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
