The logic at em28xx_isoc_dvb_max_packetsize() sucks, at least for newer the needed packet size. Yet, it is better than nothing. Rewrite the code in order to change the default to 752 for em2884 and newer chips and provide a better way to handle per-chipset specifics. For em2874, the current default should be enough, as the only em2874 board is currently a 1-seg ISDB-T board, so, it needs only a limited amount of bandwidth.

Currently, the driver assumes that all QAM carriers are spaced with 8MHz. This is wrong, and may decrease QoS on Countries like Brazil, that have DVB-C carriers with 6MHz-spaced. Fortunately, both ITU-T J-83 and EN 300 429 specifies a way to associate the symbol rate with the bandwidth needed for it. For ITU-T J-83 2007 annex A, the maximum symbol rate for 6 MHz is: 6 MHz / 1.15 = 5217391 Bauds For ITU-T J-83 2007 annex C, the maximum symbol rate for 6 MHz is: 6 MHz / 1.13 = 5309735 Bauds. As this tuner is currently used only for DRX-K, and it is currently hard-coded to annex A, I've opted to use the roll-off factor of 0.15, instead of 0.13. If we ever support annex C, the better would be to add a DVB S2API call to allow changing between Annex A and C, and add the 0.13 roll-off factor to it. This code is currently being used on other frontends, so I think we should later add a core function with this code, to warrant that it will be properly implemented everywhere. Signed-off-by:

added new bit offset defines, more supported BE colour formats and also support BGR565 swapped pixel formats removed pixfmt helper functions and option flags setting the configuration register directly in set_pixfmt added reg_mask function reg_mask is basically the same as clearing & setting registers, but it is more convenient and faster (saves one rw cycle).

Add media bus configuration types and two subdev operations to get supported mediabus configurations and to set a specific configuration. Subdevs can support several configurations, e.g., they can send video data on 1 or several lanes, can be configured to use a specific CSI-2 channel, in such cases subdevice drivers return bitmasks with all respective bits set. When a set-configuration operation is called, it has to specify a non-ambiguous configuration. Signed-off-by:

The camera there identifies itself as being manufactured by Cheng Uei Precision Industry Co., Ltd (Foxlink), and product is titled as "HP Webcam [2 MP Fixed]". I was trying to get 2 USB video capture devices to work simultaneously, and noticed that the above mentioned webcam always requires packet size = 3072 bytes per micro frame (~= 23.4 MB/s isoc bandwidth), which is far more than enough to get standard NTSC 640x480x2x30 = ~17.6 MB/s isoc bandwidth.

The signal state field in G_TUNER is typically scaled from 0-100%. Since we don't know the signal level, we really would prefer the field to contain 100% than 1/256, which in many utilities (such as v4l2-ctl) rounds to 0% even when a signal is actually present. This patch makes the behavior consistent with other drivers. Signed-off-by:

Make use of the signal state registers to properly populate the signal lock registers in the cx231xx driver. This allows applications to know whether there is a signal present even in devices which lack a tuner (since such apps typically won't call G_TUNER if no tuner is present).

On platforms that have CONFIG_HZ set to 100, the power ramp time effectively ends up being 10ms. However, on those that have a higher CONFIG_HZ, the time ends up *actually* being 5ms, which doesn't allow enough time for the hardware to be fully powered up before attempting to address it via i2c. Change the constant to 10ms, which is long enough for the hardware to power up, and won't really be anymore time than it was previously on platforms with CONFIG_HZ being 100. Credit goes to Mauro Carvalho Chehab and Gerd Hoffmann who previously investigated this issue. Tested with the Hauppauge USBLive 2, with which the problem was readily reproducible after setting CONFIG_HZ to 1000. Signed-off-by:

The following patch addresses the regression introduced in the cx231xx driver which stopped the Hauppauge USBLive2 from working. Confirmed working by both myself and the user who reported the issue on the KernelLabs blog (Robert DeLuca). At some point during refactoring of the cx231xx driver, the USBLive 2 device became broken. This patch results in the device working again. Thanks to Robert DeLuca for sponsoring this work.

The search for matching extension units fails to take account of the current chain. In the case where you have two distinct video chains, both containing an XU with the same GUID but different unit ids, you will be unable to perform a mapping on the second chain because entity on the first chain will always be found first Fix this by only searching the current chain when performing a control mapping. This is analogous to the search used by uvc_find_control(), and is the correct behaviour. Signed-off-by:

The error propagation changeset c23bf4402 broke the DVB-T code. The legacy way for propagate errors was: do { status = foo_func() if (status < 0) break; } while (0); return status; However, on a few places, it was doing: do { switch(foo) { case bar: status = foo_func() if (status < 0) break; break; } switch(foo2) { case bar: status = foo_func() if (status < 0) break; break; } ... } while (0); return (status) The inner error break were not working, as it were breaking only the switch, instead of the do. The solution used were to do a s/break/goto error/ at the inner breaks, but preserving the last break. Onfortunately, on a few switches, the replacement were applied also to the final break for the case statements. Fix the broken logic, by reverting them to break, where pertinent, in order to fix DVB-T support. Signed-off-by:
