[media] mt9t001: Aptina (Micron) MT9T001 3MP sensor driver · 0a54b86a

由 Laurent Pinchart 提交于 6月 14, 2010

The MT9T001 is a parallel 3MP sensor from Aptina (formerly Micron)
controlled through I2C.

The driver creates a V4L2 subdevice. It currently supports binning and
cropping, and the gain, exposure, test pattern and black level controls.

[media] omap3isp: video: Avoid crashes when pipeline set stream operation fails · 5b6c3ef0

由 Laurent Pinchart 提交于 8月 13, 2011

If streaming can't be enabled on the pipeline, the DMA buffers queue is
not emptied. If the buffers then get freed the queue will end up
referencing free memory. This is usually not an issue, as the DMA queue
will be reinitialized the next time streaming is enabled, before
enabling the hardware.

However, if the sensor connected at the pipeline input is free-running,
the CCDC will start generating interrupts as soon as it gets powered up,
before the streaming gets enabled on the hardware. This will make the
CCDC interrupt handler access freed memory, causing a crash.

Reinitialize the DMA buffers queue in isp_video_streamon() if the error
path to make sure this situation won't happen.

[media] omap3isp: Don't fail streamon when the sensor doesn't implement s_stream · c62e2a19

由 Laurent Pinchart 提交于 8月 13, 2011

The code handles subdevs with no s_stream operation correctly, but
returns -ENOIOCTLCMD by mistake if the first subdev in the chain has no
s_stream operation. Return 0 in that case.

[media] imon: don't parse scancodes until intf configured · 6f6b90c9

由 Jarod Wilson 提交于 7月 19, 2011

The imon devices have either 1 or 2 usb interfaces on them, each wired
up to its own urb callback. The interface 0 urb callback is wired up
before the imon context's rc_dev pointer is filled in, which is
necessary for imon 0xffdc device auto-detection to work properly, but we
need to make sure we don't actually run the callback routines until
we've entirely filled in the necessary bits for each given interface,
lest we wind up oopsing. Technically, any imon device could have hit
this, but the issue is exacerbated on the 0xffdc devices, which send a
constant stream of interrupts, even when they have no valid key data.

[media] STV0288 frontend provide wider carrier search and DVB-S2 drop out. resend · 59152b1c

由 tvboxspy 提交于 7月 10, 2011

The following patch provides wider carrier search.

As with existing code search starts at MSB aligned. The boundary
is widened to start at -9.  In order to save time, if no carrier is
detected at the start it advances to the next alignment until carrier
is found.

The stv0288 will detect a DVB-S2 carrier on all steps , a
time out of 11 steps is introduced to drop out of the loop.

In stv0288_set_symbol carrier and timing loops are restored to
default values (inittab) before setting the symbol rate on each tune. A
slight drift was noticed with full scan in the higher IF frequencies of
each band.

[media] noon010pc30: Conversion to the media controller API · 6426e14a

由 Sylwester Nawrocki 提交于 9月 16, 2011

Replace g/s_mbus_fmt ops with the pad level get/set_fmt operations.
Add media entity initialization and set subdev flags so the host driver
creates a subdev device node for the driver.
A mutex was added for serializing the subdev operations. When setting
format is attempted during streaming an (EBUSY) error will be returned.

After the device is powered up it will now remain in "power sleep"
mode until s_stream(1) is called. The "power sleep" mode is used
to suspend/resume frame generation at the sensor's output through
s_stream op.
