2013-03-04[media] mb86a20s: don't allow updating signal strength too fastMauro Carvalho Chehab1-7/+17
Getting signal strength requires some loop poking with I2C. Don't let it happen too fast. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-04[media] mb86a20s: Fix signal strength calculusMauro Carvalho Chehab1-1/+1

2013-03-04[media] mb86a20s: provide CNR stats before FE_HAS_SYNCMauro Carvalho Chehab1-8/+16
State 9 means TS started to be output, and it should be associated with FE_HAS_SYNC. The mb86a20scan get CNR statistics at state 7, when frame sync is obtained. As CNR may help to adjust the antenna, provide it earlier. A latter patch could eventually start outputing MER measures earlier, but that would require a bigger change, and probably won't be better than the current way, as the time between changing from state 8 to 9 is generally lower than the time to get the stats collected.

2013-03-04[media] mb86a20s: adjust IF based on what's set on the tunerMauro Carvalho Chehab1-4/+53
Instead of hardcoding a fixed IF frequency of 3.3 MHz, use the IF frequency provided by the tuner driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-03-04[media] em28xx: extract the device configuration dataset from eeproms with ↵Frank Schaefer2-36/+85
16 bit address width The new eeproms with 16 address width still have the the device config dataset (the content of the old 8 bit eeproms) embedded. Hauppauge also continues to include the tveeprom data structure inside this dataset in their devices. The start address of the dataset depends on the start address of the microcode and a variable additional offset. It should be mentioned that Camera devices seem to use a different dataset type, which is not yet supported. Tested with devices "Hauppauge HVR-930C". I've also checked the USB-log from the "MSI Digivox ATSC" and it works the same way.

2013-03-04[media] em28xx: do not store eeprom content permanentlyFrank Schaefer3-15/+31
We currently reserve an array of 256 bytes for the eeprom content in the device struct. For eeproms with 16 bit address width it might even be necessary to increase the buffer size further. Having such a big chunk of memory reserved even if the device has no eeprom and keeping it after it has already been processed seems to be a waste of memory. Change the code to allocate + free the eeprom memory dynamically. This also makes it possible to handle different dataset sizes depending on what is stored/found in the eeprom.

2013-03-04[media] em28xx: add helper function for reading data blocks from i2c clientsFrank Schaefer1-28/+46
Add a helper function for reading data blocks from i2c devices with 8 or 16 bit address width and 8 bit register width. This allows us to reduce the size of new code added by the following patches. Works only for devices with activated register auto incrementation. Signed-off-by: Frank Schäfer <fschaefer.oss@googlemail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-04[media] em28xx: add basic support for eeproms with 16 bit address widthFrank Schaefer3-25/+49
Newer devices (em2874, em2884, em28174, em25xx, em27[6,7,8]x) use eeproms with 16 bit instead of 8 bit address width. The used eeprom type depends on the chip type, which makes sure eeproms can't be damaged. This patch adds basic support for 16 bit eeproms only, which includes - reading the content - calculating the eeprom hash - displaying the content The eeprom content uses a different format, for which support will be added with subsequent patches. Tested with the "Hauppauge HVR-930C" and the "Speedlink VAD Laplace webcam" (with additional experimental patches).

2013-03-04[media] em28xx: fix eeprom data endianessFrank Schaefer2-16/+18
The data is stored as little endian in the eeprom. Hence the correct data types should be used and the data should be converted to the machine endianess before using it. The eeprom id (key) also isn't a 32 bit value but 4 separate bytes instead.

2013-03-04[media] em28xx: do not interpret eeprom content if eeprom key is invalidFrank Schaefer1-2/+6
If the eeprom key isn't valid, either a different (currently unknown) format is used or the eeprom is corrupted. In both cases it doesn't make sense to interpret the data.

2013-03-04[media] em28xx-i2c: also print debug messages at debug level 1Frank Schaefer1-6/+6
The current code uses only a single debug level and all debug messages are printed for i2c_debug >= 2 only. So debug level 1 is actually the same as level 0, which is odd. Users expect debugging messages to become enabled for anything else than debug level 0.

The em28xx driver has changed much, especially since kernel 3.8. So it's time to bump the driver version. Changes since kernel 3.8: - converted the driver to videobuf2 - converted the driver to the v4l2-ctrl framework - added USB bulk transfer support - use USB bulk transfers by default for webcams (allows streaming from multiple devices at the same time) - added image quality bridge controls: contrast, brightness, saturation, blue balance, red balance, sharpness - removed dependency from module ir-kbd-i2c - cleaned up the frame data processing code - removed some unused/obsolete code - made remote controls of devices with external (i2c) receiver/decoder work again - fixed audio over USB for device "Terratec Cinergy 250" - several v4l2 compliance fixes and improvements (including fixes for ioctls enabling/disabling) - lots of further bug fixes and code improvements Signed-off-by: Frank Schäfer <fschaefer.oss@googlemail.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-02-16Revert "[media] dvb_frontend: return -ENOTTY for unimplement IOCTL"Mauro Carvalho Chehab1-3/+3
As reported by Klaus Schmidinger: "In VDR I use an ioctl() call with FE_READ_UNCORRECTED_BLOCKS on a device (using stb0899). After this call I check 'errno' for EOPNOTSUPP to determine whether this device supports this call. This used to work just fine, until a few months ago I noticed that my devices using stb0899 didn't display their signal quality in VDR's OSD any more. After further investigation I found that ioctl(FE_READ_UNCORRECTED_BLOCKS) no longer returns EOPNOTSUPP, but rather ENOTTY. And since I stop getting the signal quality in case any unknown errno value appears, this broke my signal quality query function." While the changes reflect what is there at: http://comments.gmane.org/gmane.linux.kernel/1235728 it does cause regression on userspace. So, revert it to stop the damage. This reverts commit 177ffe506cf8 ("[media] dvb_frontend: return -ENOTTY for unimplement IOCTL").

2013-02-15Merge branch 'omap/multiplatform-fixes', tag 'v3.8-rc5' into next/multiplatformArnd Bergmann12-69/+58
The omap multiplatform support uncovered a bug in the cwdavinci_cpdma code and was missing two drivers that are enabled now but are not quite ready for multiplatform, as found by allyesconfig builds. There is also a conflict generated by automated merge in arch/arm/mach-omap2/drm.c between a bug fix that went into v3.8-rc5 and a different version of the same fix that went into the omap/multiplatform branch. This merge removes the extraneous #include that was causing build errors. * omap/multiplatform-fixes: net: cwdavinci_cpdma: export symbols for cpsw remoteproc: omap: depend on OMAP_MBOX_FWK [media] davinci: do not include mach/hardware.h Signed-off-by: Arnd Bergmann <arnd@arndb.de>
