2008-06-05V4L/DVB (7970): mix trivial endianness annotationsAl Viro
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-05-14V4L/DVB (7848): Fix dependencies for tuner-xc2028 and em28xx-dvbMauro Carvalho Chehab
em28xx-dvb doesn't need FW_LOADER. Instead, tuner-xc2028 needs to select FW_LOADER. Also, this can happen only if HOTPLUG is selected, since FW_LOADER is dependent on HOTPLUG. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-05-14V4L/DVB (7846): Re-creates VIDEO_TUNERMauro Carvalho Chehab
VIDEO_TUNER is responsible for compilation of tuners.ko module. This were the previous behaviour before the creation of MEDIA_TUNER. Before this patch, tuner.ko were created even for drivers that don't need a tuner (like webcam drivers). Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

namespace for all of them.
2008-04-29V4L/DVB(7767): Move tuners to common/tunersMauro Carvalho Chehab
There were several issues in the past, caused by the hybrid tuner design, since now, the same tuner can be used by drivers/media/dvb and drivers/media/video. Kconfig items were rearranged, to split V4L/DVB core from their drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-26V4L/DVB (7734): em28xx: copy and paste error in em28xx_init_isocJanne Grunau
Fixes a copy and paste error in check of kzalloc return value. The check block was copied from the previous allocation but the variable wasn't exchanged. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7652): em28xx: Drop the severity level of the "urb resubmit failed"Devin Heitmueller
em28xx-core.c - Drop the severity level of the "urb resubmit failed" to debug, since it occurs every time a stream disconnects, which fills the dmesg log Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-04-24V4L/DVB (7619): em28xx: adds proper demod IF for HVR-900Mauro Carvalho Chehab
Thanks to Aidan Thornton <makosoft@googlemail.com> for helping to test this firmware Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7618): em28xx: make some symbols staticMauro Carvalho Chehab

2008-04-24V4L/DVB (7617): Removes a manual mode setupMauro Carvalho Chehab
The setup is already done at open(). Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7616): em28xx-dvb: Properly selects digital mode at the right placeMauro Carvalho Chehab
The driver should be switched to digital mode, when trying to access the frontend or when streaming. This patch provides the correct code to support this feature. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7615): em28xx: Provide the proper support for switching between ↵Mauro Carvalho Chehab
analog/digital Before this patch, HVR900/HVR950 were incorreclty going back to analog. The result is that only digital were working. This patch provides the proper setup for analog/digital and tuner callback. It also properly resets analog into a sane state at open(). Thanks to Steven Toth <stoth@linuxtv.org> and Michael Krufky <mkrufky@linuxtv.org> for helping to set the proper parameters to GPO/GPIO em2883 ports. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7614): em28xx-core: fix some debug printk's that wrongly received ↵Mauro Carvalho Chehab
KERN_INFO Those printk's were adding more info to a line that were already being printed. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7613): em28xx: rename registersMauro Carvalho Chehab
Now, all registers will follow the same convension: EM28XX_R<reg_number>_<reg_name> This allows to associate a register with its value, and also with a canonical name. Also, registers that are specific to a given chip were renamed accordingly, as EM2800_foo (for 2800 only registers) or EM2880_foo (for registers that started to appear on em2880). Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7612): em28xx-cards: use register names for GPIO/GPOMauro Carvalho Chehab
Before this patch, registers 0x04 and 0x08 were referenced by its value. This is bad, since makes harder for someone to understand what this is doing. This patch renames those two registers into an appropriate name. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7611): em28xx: Move registers to a separate fileMauro Carvalho Chehab
em28xx.h contains lots of different stuff inside. The better is to break it on some files. This patch removes the register names, moving them to a separate file. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7610): em28xx: Select reg wait time based on chip IDMauro Carvalho Chehab
This is more conservative than just removing the msleep() from em28xx_write_regs_req(), since some old hardware may still need it. So, it will remove the sleep time only for those chips where this removal were tested. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7609): em28xx-core: speed-up firmware loadDevin Heitmueller
em28xx-core.c: - Remove sleep in i2c message routine which slows down i2c by a factor 10x. Load time for BASE firmware went from 13s to .973s Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7608): em28xx-dvb: Some cleanups and fixesDevin Heitmueller
em28xx-dvb.c: - Remove unneeded xc3028_ctrl structure. The driver automatically preserves the previous value tuner-xc2028.c: - Make the return type for xc2028_get_reg signed, since all of the callers are looking for "< 0" to detect errors.

2008-04-24V4L/DVB (7604): em28xx-dvb: Fix analog modeMauro Carvalho Chehab
The analog entries are wrong. Fix it. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7603): em28xx-dvb: don't use videobuf-dvbAidan Thornton
Modifies em28xx-dvb not to use videobuf-dvb, but instead to include the code for registering dvb devices locally and use the URB management code in the em28xx driver directly. DVB data streaming should now work. Signed-off-by: Aidan Thornton <makosoft@googlemail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7602): em28xx: generalise URB setup codeAidan Thornton
Move the URB setup and management code to em28xx-core.c and generalise it slighlty so that the DVB code can use it. Signed-off-by: Aidan Thornton <makosoft@googlemail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7601): em28xx-dvb: add support for the HVR-900Aidan Thornton
Adds the correct GPIOs and demod attach code for the HVR-900 Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7600): em28xx: Sets frequency when changing to analog modeMauro Carvalho Chehab
This will make tuner-xc2028 to change to analog, if needed. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7599): em28xx-dvb: videobuf callbacks are waiting for em28xx_fhMauro Carvalho Chehab
Thanks to Devin Heitmueller <devin.heitmueller@gmail.com> for pointing this issue. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7598): em28xx: several fixes on gpio programmingDevin Heitmueller
em28xx-cards.c: - Fix reversed val/rst values in both analog_gpio and digital_gpio vectors - Fix crash that would was occurring during every analog startup while looping over gpio_ctl - Remove what appears to be a redundant setting of gpio_ctl->val - Don't use OREN538 demodulation for the HVR-950 (prevents ATSC scanning from working) em28xx-dvb.c: - Tuner should be in digital mode when issuing the reset - Add copyright - Change struct definition (corresponds to fix in em28xx-cards.c for gpio_ctl looping) Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7597): em28xx: share the same xc3028 setup for analog and digital modesMauro Carvalho Chehab
Thanks to Devin Heitmueller <devin.heitmueller@gmail.com> and Aidan Thornton" <makosoft@googlemail.com> for pointing some errors with the previous scenario. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7596): em28xx-dvb: Add support for HVR950Mauro Carvalho Chehab
This patch adds DVB support for Hauppauge HVR950. Thanks to Michael Krufky <mkrufky@linuxtv.org> for getting those values. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7595): Improve generic support for setting gpio valuesMauro Carvalho Chehab
em28xx based devices with xc3028 may require some specific gpio values. This patch adds a generic handling for such values. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7594): em28xx: Fix KconfigMauro Carvalho Chehab
Some devices have msp3400 audio decoder chip. Selects it, if em28xx. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7593): em28xx: add a module to handle dvbMauro Carvalho Chehab
This patch adds em28xx-dvb. This driver is highly based on cx88-dvb and saa7134-dvb. This code currently loads and unloads successfully. However, some changes are needed to properly support the mpeg streams and to setup em28xx to work on DVB mode. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7567): em28xx: Some cleanupsMauro Carvalho Chehab
Removes some fields from data structs. There are some fields that are just caching some calculus for buffer size. The calculus were moved to the places it were needed and the now unused fields were removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7565): em28xx: fix buffer underrun handlingAidan Thornton
This patch fixes three related issues and a fourth trivial one: - Use buffers even if no-one's currently waiting for them (fixes underrun issues); - Don't return incomplete/mangled frames at the start of streaming and in the case of buffer underruns; - Fix an issue which could cause the driver to write to a buffer that's been freed after videobuf_queue_cancel is called (exposed by the previous two fixes - for some reason, ignoring buffers that weren't being waited on worked around the issue); - Fix a bug which could cause only one field to be filled in the first buffer (or first few buffers) after streaming is started.

Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7563): em28xx: Add missing checksMauro Carvalho Chehab
There are some cases where nobody is waiting for a buffer. Due to the lack of check, if you try to abort the userspace app, machine were hanging, since IRQ were trying to use a buffer that were disallocated. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7559): em28xx: Fills the entire buffer, before getting another oneMauro Carvalho Chehab

2008-04-24V4L/DVB (7556): em28xx: fix locking on vidioc_s_fmt_capAidan Thornton
Currently, vidioc_s_fmt_cap is allowed even if streaming is running on some other fh. This is likely to cause issues. Block use of vidioc_s_fmt_cap if someone else has claimed access to the device.

2008-04-24V4L/DVB (7555): em28xx: remove timeoutMauro Carvalho Chehab
It seems that we don't need a timeout for em28xx. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7550): em28xx: Fix a possible memory leakBrandon Philips
I did notice a possible memory leak since iolock is could possibly be called before a buffer has been freed. This ensure s_fmt isn't called while the queue is busy thereby avoiding iolock on already allocated buffers. Signed-off-by: Brandon Philips <bphilips@suse.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7549): em28xx: some small cleanupsMauro Carvalho Chehab
- Remove dead code; - Fix a few CodingStyle issues; - Prints frame number, if debug is enabled. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-24V4L/DVB (7548): Various fixes for the em28xx videobuf codeAidan Thornton
- Aborting buffer_filled if no-one's waiting on the waitqueue probably isn't what we want, since just because no-one's waiting for it now doesn't mean they wouldn't dequeue it in time. (vivi gets away with this, possibly because it can fill each buffer much faster.) - The first BUG_ON(lencopy <= 0); really isn't worth causing a kernel panic over, especially since there are some reasons why it could trigger in normal use. - The top and botom frames are actually the wrong way around.
