2014-11-25[media] DVB-frontends: Deletion of unnecessary checks before the function ↵Markus Elfring4-8/+4
call "release_firmware" GIT_AUTHOR_DATE=1416472432 The release_firmware() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed.

The Silicon Labs Si2146 tuner seems to work with the same driver as the Si2157, but there a few exceptions. The powerup command seems to be quite a bit different. In addition there's a property 0207 that requires a different value. Thus another entry is created in the si2157_id table to support also si2146 in this driver.

2014-11-25[media] vb2: use dma_map_sg_attrs to prevent unnecessary syncHans Verkuil2-10/+47
By default dma_map_sg syncs the mapped buffer to the device. But buf_prepare expects a buffer syncs for the cpu and the buffer will be synced to the device in the prepare memop. The reverse is true for dma_unmap_sg, buf_finish and the finish memop. To prevent unnecessary syncs we ask dma_(un)map_sg to skip the sync.

2014-11-25[media] vb2-dma-sg: move dma_(un)map_sg hereHans Verkuil14-130/+64
This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the prepare/finish memops. Now that vb2-dma-sg will sync the buffers for you in the prepare/finish memops we can drop that from the drivers that use dma-sg. For the solo6x10 driver that was a bit more involved because it needs to copy JPEG or MPEG headers to the buffer before returning it to userspace, and that cannot be done in the old place since the buffer there is still setup for DMA access, not for CPU access. However, the buf_finish op is the ideal place to do this. By the time buf_finish is called the buffer is available for CPU access, so copying to the buffer is fine.

Chip version RTL2832P has extra TS interface for connecting slave demodulator. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
