| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | stb0899: fix the limits for signal strength values stb0899_read_signal_strength() adds an offset to the result of the table lookup. That offset must correspond to the lowest value in the lookup table, to make sure the result doesn't get below 0, which would mean a "very high" value since the parameter is unsigned. 'strength' and 'snr' need to be initialized to 0 to make sure they have a defined result in case there is no "internal->lock".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is mostly copy/paste of the 520e code with setting GPIO7 removed (no LED light). I've worked on just released vanilla linux-3.3.0 kernel, so there may be 1/2 lines offset to the internal working source, but most of the code should apply cleanly. I was able to get the DVB-C working (tuned and watched TV). Haven't tested DVB-T (no signal atm). Special thanks to everybody who worked on the code and to Antti Palosaari and Devin Heitmueller who provided essential support on irc.

| * [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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | 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] 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. Kernel Crash Dump: ------------------ designware_udc designware_udc: Device Synopsys UDC probed csr 90810000: plug 90812000 g_webcam gadget: uvc_function_bind Unable to handle kernel NULL pointer

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
