* [media] pvrusb2: fix 7MHz & 8MHz DVB-T tuner support for HVR1900 rev D1F5Michael Krufky2012-03-191-0/+10
| | | | | | | | | | | | | | | | | The D1F5 revision of the WinTV HVR-1900 uses a tda18271c2 tuner instead of a tda18271c1 tuner as used in revision D1E9. To account for this, we must hardcode the frontend configuration to use the same IF frequency configuration for both revisions of the device. 6MHz DVB-T is unaffected by this issue, as the recommended IF Frequency configuration for 6MHz DVB-T is the same on both c1 and c2 revisions of the tda18271 tuner.

| | | | | | | | | | We still need to power up the controller to avoid unsightly self-immolation should something try to access its registers, but the sensor can stay powered down unless the camera was actually operating at suspend time.

* [media] marvell-cam: fix the green screen of deathJonathan Corbet2012-03-191-7/+6
| | | | | | | | | | | | | | | | I had learned through hard experience that dinking around with the DMA descriptors while the C1_DESC_ENA enable bit was set is a recipe for all kinds of truly malicious behavior on the hardware's part, regardless of whether the DMA engine is actually operating at the time. That notwithstanding, the driver did so dink, resulting in "green frame" captures and the death of the system in random, spectacular ways. Move the tweaking of C1_DESC_ENA to the same function that sets the descriptor so we know that we'll never try to set a descriptor while that bit is set.

* [media] marvell-cam: Increase the DMA shutdown timeoutJonathan Corbet2012-03-191-1/+9
| | | | | | | | | | Experience shows that, on the Armada platform, it can take as much as 120ms for the DMA engine to actually shut down after it has been told to. So a 40ms timeout is not adequate; use 150ms instead. Also make sure we don't leave the DMA_ACTIVE flag set once things are down.

* [media] marvell-cam: Remove broken "owner" logicJonathan Corbet2012-03-192-5/+1
| | | | | | | | | | | The marvell cam driver retained just enough of the owner-tracking logic from cafe_ccic to be broken; it could, conceivably, cause the driver to release DMA memory while the controller is still active. Simply remove the remaining pieces and ensure that the controller is stopped before we free things.

| | | | | | | | | | | | | | | | | | The i2c failures were caused by enabling both i2c gates at the same time while putting the tuners asleep. This patch removes the init() and sleep() callbacks from the tuner, to prevent frontend.c from calling i2c_gate_ctrl tuner init / sleep i2c_gate_ctrl without holding the lock. tuner init() and sleep() are instead called in frontend init() and sleep().

| | | | | | | | | | | | | | | | | Media-related drivers living outside drivers/media/ (such as the UVC gadget driver in drivers/usb/gadget/) rely on the media core being initialized before they're probed. As drivers/usb/ is linked before drivers/media/, this is currently not the case and will lead to crashes if the drivers are not compiled as modules. Register media_devnode_init() as a subsys_initcall() instead of module_init() to fix this.

* [media] V4L/v4l2-dev: Make 'videodev_init' as a subsys initcallBhupesh Sharma2012-03-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the V4L2 based UVC webcam gadget (g_webcam) expects the 'videodev' to present when the 'webcam_bind' routine is called, so 'videodev' should be available as early as possible. Now, when 'g_webcam' is built as a module (i.e. not a part of kernel) the late availability of 'videodev' is OK, but if 'g_webcam' is built statically as a part of the kernel, the kernel crashes (a sample crash dump using Designware 2.0 UDC is provided below). To solve the same, this patch makes 'videodev_init' as a subsys initcall.

* [media] v4l: Add driver for Micron MT9M032 camera sensorMartin Hostettler2012-03-193-0/+877
| | | | | | | | | | | | | | | | The MT9M032 is a parallel 1.6MP sensor from Micron controlled through I2C. The driver creates a V4L2 subdevice. It currently supports cropping, gain, exposure and v/h flipping controls in monochrome mode with an external pixel clock.
