2008-04-02videobuf-vmalloc.c: Fix hack of postponing mmap on remap failureBrandon Philips
In videobuf-vmalloc.c remap_vmalloc_range is failing when applications are trying to mmap buffers immediately after reqbuf. It fails because the vmalloc area isn't setup until the first QBUF when drivers call iolock. This patch introduces mmap_setup to the qtype_ops and it is called in __videobuf_mmap_setup if the buffer type is mmap. In the case of vmalloc buffers this calls iolock, and sets the state to idle. I don't think this is needed for dma-sg buffers and it defaults to a no-op for everything but vmalloc.

2008-04-02videobuf-vmalloc.c: Remove buf_release from videobuf_vm_closeBrandon Philips
Remove the buf_release on vm_close because it will lead to a buffer being released multiple times since all buffers are already freed under the two possible cases: device close or STREAMOFF.

From: Michael Krufky <mkrufky@linuxtv.org> tuner-simple is the only module that uses tuner-types - these will be merged to a single module in the future.

From: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> In case of muliple cameras, handled by the same driver, they can support different picture formats, therefore formats and num_formats cannot belong to soc_camera_ops, which is only one per driver, move them to soc_camera_device, which is one per device instance. OTOH, probe and remove methods are always the same, move them to soc_camera_ops.

2008-03-27Add support for Kworld ATSC 120Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> This board has a s5h1409 demod, plus a xc30x8 tuner (probably, xc3018). This patch adds proper support for radio, video, s-video, composite and ATSC. However, support for radio and video depends on having s5h1409 i2c gate open, otherwise, xc30x8 chip won't be visible. For a better support, some rework is needed on cx88 driver, to allow adding xc30x8 to i2c bus without sending i2c 0 byte reading to 0xc2 address. Thanks to Vanessa Ezekowitz <vanessaezekowitz@gmail.com> for helping to figure out the proper parameters for s5h1409 and the GPIO pins used by each configuration.

2008-03-21Removes video_dev from tuner-xc2028 config structMauro Carvalho Chehab
The video_dev parameter, on tuner-xc2028 were used to pass i2c private data to tuner_callback. Since the driver already have a pointer to i2c_adap->algo_data, uses this instead. This parameter were used also as a magic number to idenfity if two drivers are trying to register the same xc3028 tuner. This occurs with boards with DVB support, where both DVB and V4L drivers will share the same tuner. Instead of using the algo_data as a private number, after this patch, the driver will use i2c_adap->dev, with seems more consistent. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-10-30V4L: struct device - replace bus_id with dev_name(), dev_set_name()Mauro Carvalho Chehab
From: Kay Sievers <kay.sievers@vrfy.org> This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.
