2008-02-26 em28xx: Correct use of ! and &Mauro Carvalho Chehab
From: Julia Lawall <julia@diku.dk> In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

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.

2008-01-24em28xx: 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>

2008-01-06Request snd-usb-audio for devices with Audio Class supportMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Before this patch, only Vendor Class audio support were loaded. This means that older em28xx devices won't have digital audio support loaded. This patch changes the logic to auto load eighter snd-usb-audio, for devices with USB Audio Class or em28xx-alsa, for devices with USB Vendor Class.

2008-01-06Avoid causing regressions for non-HVR950 boardsMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Only HVR950 has analog_gpio configured. It makes no sense to set gpio to 0 for other boards. Better to add a test, while this var is not set for all xc3028 devices. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

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>

2008-01-05Adds em28xx-audio moduleMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> em28xx-audio module exports em28xx Vendor Class audio as an -alsa driver. This module were written based on usbaudio driver by Markus Rechberger.

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>
2007-12-17V4L/DVB (em28xx): Add support for Pinnacle Dazzle DVC 100Mauro Carvalho Chehab
From: Aurelien Jarno <aurelien@aurel32.net> The patch below adds the "Pinnacle Dazzle DVC 100" to the list of cards supported by the em28xx driver. As the configuration is the same as the DVC 90 one, it simply adds a new USB ID to the list of devices supported by the DVC 90 configuration.

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>
2007-11-11Convert em28xx to video_ioctl2Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Uses the newer ioctl handler at videodev. This patch also cleans up some bad logic at the driver and do CodingStyle and other cleanups at the resulting driver. Also, since VIDIOCMBUF were not working, the V4L1 compat code were removed. The compat code will eventually be re-inserted, if we find a clean way for implementing compatibility with the old API. 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.

From: Sascha Sommer <saschasommer@freenet.de> Adds autodetection support for the Cinergy200 USB and the VGear PocketTV.

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>
