Restarting stream fails quite often. Small delay is between urb killing and stream stop command - likely to give harware some time to process killed urbs. Signed-off-by:

It looks like there is some extra data carried to enhance sampling results. When you tune to some some weak/empty channel those bits are always zeroes. When you tune to some channel where is very strong signals those bits are all zeroes. Examining those 32-bits reveals shortly there is 16 pieces of 2-bit numbers. Number seen are 0, 1 and 3 - for some reason 2 is not used. I used that number to shift bits given amount to left, "increasing" sampling resolution by 3-bits. It may be wrong, but after some testing it still provides better signal. Signed-off-by:

Whilst Quadrature Sampling is most common sampling technique used in radio technology there is others too. Add control user could select sampling mode. We currently support only quadrature sampling. Signed-off-by:

It is first Kernel software defined radio receiver driver. That device is sold as a digital television solution. MSi3101 is reference design which consists of two chips: 1) MSi2500 USB ADC 2) MSi001 RF-tuner Driver is put to staging as API is not ready. Signed-off-by:

When gsc is in runtime suspended state, there is no need to call m2m_suspend during suspend and similarly, there is no need to call m2m_resume during resume if already in runtime suspended state. This patch adds the necessary conditions to achieve this. Signed-off-by:

With synchronous subdevice probing regulators should be requested by the soc-camera core in soc_camera_pdrv_probe(). Subdevice drivers, supporting asynchronous probing, call soc_camera_power_init() to request regulators. Erroneously, the same regulator array is used in the latter case as in the former, which leads to a failure. This patch fixes it by preventing the second regulator request from being executed.

[Sergei: removed deprecated IRQF_DISABLED flag, reordered/renamed 'enum chip_id' values, reordered rcar_vin_id_table[] entries, removed senseless parens from to_buf_list() macro, used ALIGN() macro in rcar_vin_setup(), added {} to the *if* statement and used 'bool' values instead of 0/1 where necessary, removed unused macros, done some reformatting and clarified some comments.] Signed-off-by:Vladimir Barinov <vladimir.barinov@cogentembedded.com> Signed-off-by:

Use the new blanking and frame size defines. This also fixed a bug in these drivers: they assumed that the height for interlaced formats was the field height, however height is the frame height. So the height for a field is actually bt->height / 2. Signed-off-by:

v4l2-common.c contained a bunch of dv-timings related functions. Move that to the new v4l2-dv-timings.c which is a more appropriate place for them. There aren't many drivers that do HDTV, so it is a good idea to separate common code related to that into a module of its own. Signed-off-by:
