| * [media] v4l: s5p-tv: add drivers for HDMI on Samsung S5P platformTomasz Stanislawski2011-07-27

| * [media] cx88: properly maintain decoder config when using MPEG encoderDevin Heitmueller2011-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cx88 driver would force core->input to always be zero when doing the the request_acquire(). While it wasn't actually changing the input register in the hardware, the driver makes decision based on the current input. In particular, it decides whether to do things like enabling the comb filter when on a composite input but disabling it on s-video. So for example, on the HVR-1300, using the s-video input with the MPEG encoder would end up with the video decoder core configured as though the input type were composite. In short, the driver state did not match the hardware state. This patch does two things: 1. It forces the input to zero only if actually switching to DVB mode. This prevents the input from changing when the blackbird driver opens the device. 2. Keep track of what the input was set to when switching to DVB, and reset it back when done. This eliminates a condition where for example the user had the analog side of the board set to capture on the s-video input, then he used DVB for a bit, then the analog input would unexpectedly be set to the tuner input.

| * [media] marvell-cam: Allow selection of supported buffer modesJonathan Corbet2011-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Marvell camera core can support all three videobuf2 buffer modes, which is slick, but it also requires that all three modes be built and present, even though only one is likely to be used. This patch allows the supported modes to be selected at configuration time, reducing the footprint of the driver. Prior to this patch, the MMP camera driver looked like this: mmp_camera 19092 0 videobuf2_core 15542 1 mmp_camera videobuf2_dma_sg 3173 1 mmp_camera videobuf2_dma_contig 2188 1 mmp_camera videobuf2_vmalloc 1718 1 mmp_camera videobuf2_memops 2100 3 videobuf2_dma_sg,videobuf2_dma_contig,videobuf2_vmalloc Afterward, instead, with scatter/gather only configured: mmp_camera 16021 0 videobuf2_core 15542 1 mmp_camera videobuf2_dma_sg 3173 1 mmp_camera videobuf2_memops 2100 1 videobuf2_dma_sg The total goes from 43,813 bytes to 36,836. The emphasis has been on simplicity and minimal #ifdef use rather than on squeezing out every possible byte of code. For configuration, the driver simply looks at which videobuf2 modes have been configured in and supports them all; it's simplistic but should be good enough. The cafe driver is set to support vmalloc and dma-contig; mmp supports only dma-sg, since that's the only mode that really makes sense to use.

Initialise the analog tuner properly and hook up the DVB tuner and demodulator. DVB-T and analog now work (though I can't tune every DVB channel, but I think there's an issue with the aerial and signal boosters here that is causing me problems).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Looking at the pwc buffer management code has made it clear to me it needed some serious fixing. Not only was there a ton of code duplication even internally to pwc (read and mmap wait for frame code was duplicated), the code also was outright buggy. With the worst offender being dqbuf, which just round robin returned all the mmap buffers, without paying any attention to them being queued by the app with qbuf or not. And qbuf itself was a noop. So I set out to fix this and already had some cleanups in place when I read Jonathan Corbet's lwn article on videobuf2, this inspired me to just rip out the buffer management code and replace it with videobuf2, greatly reducing the amount of code, and fixing all bugs in one go: Many thanks to Jonathan for the timely article on this !

| * [media] pwc: Remove a bunch of bogus sanity checks / don't return EFAULT wronglyHans de Goede2011-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | The chances if any of these becoming NULL magically are 0% And if they do become NULL oopsing is the right thing to do (so that the user logs a bug with the kernel rather then with whatever app he was using). Returning EFAULT to userspace should only be done when userspace supplies a bad address, not on driver bugs / hw issues, so in the few cases where the check is not bogus return something else.

| | | | | | | | | | | | | | | | Just like in userspace strncpy does not guarantee 0 termination. Use strlcpy instead which does guarantee 0 termination. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| * [media] gspca: Add new se401 camera driverHans de Goede2011-07-27
| | | | | | | | | | | | | | | | Based on the old v4l1 camera by Jeroen Vreeken driver which recently got removed from the kernel. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * [media] gspca: reset image_len to 0 on LAST_PACKET when discarding frameHans de Goede2011-07-27
| | | | | | | | | | | | | | | | | | | | | | Reset image and image_len to NULL/0 on LAST_PACKET when we're in discard frame mode, just like we do when not discarding the current frame. The new se401 driver uses image_len for SOF/EOF detection and thus depends on this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| * [media] gspca - ov519: Fix sensor detection problemsJean-François Moine2011-07-27
| | | | | | | | | | | | | | | | | | The sensor of some webcams could not be detected due to timing problems in sensor register reading. This patch adds bridge register readings before sensor register reading. Signed-off-by: Jean-François Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * [media] return -ENOTTY for unsupported ioctl's at legacy driversMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | | | | | | | | | | Those drivers are not relying at the V4L2 core to handle the ioctl's. So, we need to manually patch them every time a change goes to the core.
