2012-01-15[media] dvb-core: fix a regression with MythTVMauro Carvalho Chehab1-0/+9
As reported by Lawrence[1], MythTV 0.24.1 does the wrong thing with a DVBv5 call: it fills the delivery system with SYS_UNDEFINED, expecting that the DVB core would work with that. This used to work by accident, as the DVB core were missing the check for the supported delivery systems. Yet, fixing it is easy, so let's add a logic to handle this case, to provide backward compatibility.

2012-01-11mb86a20s: Add a few more register settings at the init seqMauro Carvalho Chehab1-4/+12
Some time ago, Manoel sent us a patch adding more stuff to the init sequence. However, his patch were also doing non-related stuff, by changing the init logic without any good reason. So, it was asked for him to submit a patch with just the data that has changed, in order to allow us to better analyze it. As he didn't what it was requested, I finally found some time to dig into his init sequence and add it here. Basically, new stuff is added there. There are a few changes: 1) The removal of the extra (duplicated) logic that puts the chip into the serial mode; 2) Some Viterbi VBER measurement init data was changed from 0x00 to 0xff for layer A, to match what was done for layers B and C. None of those caused any regressions and both make sense on my eyes. The other parameters additions actually increased the tuning quality for some channels. Yet, some channels that were previously discovered with scan disappered, while others appeared instead. This were tested in Brasilia, with an external antena. At the overall, it is now a little better. So, better to add these, and then try to figure out a configuration that would get even better scanning results.

2012-01-10[media] af9005, af9015: use symbolic names for USB id table indicesJonathan Nieder2-87/+252
The af9005_properties and af9015_properties tables make use of USB ids from the USB id tables with hardcoded indices, as in "&af9015_usb_table[30]". Adding new entries before the end breaks such references, so everyone has had to carefully tiptoe to only add entries at the end of the list. In the spirit of "dw2102: use symbolic names for dw2102_table indices", use C99-style initializers with symbolic names for each index to avoid this. In the new regime, properties tables referring to the USB ids have names like "&af9015_usb_table[CINERGY_T_STICK_RC]" that do not change meaning when items in the USB id table are reordered.

2012-01-10[media] cx231xx: use URB_NO_TRANSFER_DMA_MAP on URBs allocated with ↵Thomas Petazzoni3-5/+5
usb_alloc_urb() URBs allocated with usb_alloc_urb() are allocated from DMA-coherent areas, and therefore it is not necessary to call dma_map_single() on such buffers. Worst, on ARM, calling dma_map_single() on a DMA-coherent buffer will trigger a BUG_ON() in arch/arm/mm/dma-mapping.c. Therefore, we mark all URBs allocated with usb_alloc_urb() with the URB_NO_TRANSFER_DMA_MAP transfer_flags, so that the USB core does not do dma_map_single()/dma_unmap_single() on those buffers. This is similar to 882787ff8fdeb0be790547ee9b22b281095e95da for the gspca driver, and has already been discussed on the linux-media list in the past: http://www.mail-archive.com/[email protected]/msg37086.html.

2012-01-10[media] cx231xx: Fix unregister logicMauro Carvalho Chehab5-22/+24
There are several weirdness at the unregister logic. First of all, IR has a poll thread. This thread needs to be removed, as it uses some resources associated to the main driver. So, the driver needs to explicitly unregister the I2C client for ir-kbd-i2c. If, for some reason, the driver needs to wait for a close() to happen, not all memories will be freed, because the free logic were in the wrong place. Also, v4l2_device_unregister() seems to be called too early, as devices are still using it. Finally, even with the device disconnected, there is one USB function call that will still try to talk with it. Signed-off-by: Mauro Carvalho Chehab <[email protected]>
