The switch to the new control framework caused a regression where the audio was no longer unmuted after the carrier scan finished. The original code attempted to set the volume control to its current value in order to have the set-volume control code to be called that handles the volume and muting. However, the framework will not call that code unless the new volume value is different from the old. Instead we now call msp_s_ctrl directly. It is a bit of a hack: we really need a v4l2_ctrl_refresh_ctrl function for this (or something along those lines). Thanks to Andy Walls for bisecting this and to Shane Shrybman for reporting it!

When audio is present, some alternate settings were skipped. This prevented some webcams to work, especially when bulk transfer was used. This patch permits to use the last or only alternate setting. Reported-by:

Add spacing field to v4l2_hw_freq_seek. Add V4L2_TUNER_CAP_RDS_BLOCK_IO, which indicates that the tuner/ transmitter if capable of transmitting/receiving RDS blocks. Add V4L2_TUNER_CAP_RDS_CONTROLS capability, which indicates that the RDS data is handled as values of predefined controls like radio text, program ID and so on. Signed-off-by:

Fixed problem with DiSEqC communication. The message was wrongly modulated, so the DiSEqC switch was not work. This patch fixes DiSEqC messages, simple tone burst and tone on/off. I verified it with osciloscope against the DiSEqC documentation. Interface: PCI DVB-S TV tuner TeVii S420 Kernel: 2.6.32-24-generic (UBUNTU 10.4) Signed-off-by:

This patch adds support for g_parm / s_parm operations to the SoC Camera framework. It is usefull for checking/setting camera frame rate. Example usage can be found in the previous patch from this series, "SoC Camera: add driver for OV6650 sensor". Created and tested against linux-2.6.36-rc3 on Amstrad Delta. Signed-off-by:

This patch provides a V4L2 SoC Camera driver for OV6650 camera sensor, found on OMAP1 SoC based Amstrad Delta videophone. Since I have no experience with camera sensors, and the sensor documentation I was able to find was not very comprehensive, I left most settings at their default (reset) values, except for: - those required for proper mediabus parameters and picture geometry and format setup, - those used by controls. Resulting picture quality may be far from perfect, but better than nothing. In order to be able to get / set the sensor frame rate from userspace, I decided to provide two not yet SoC camera supported operations, g_parm and s_parm. These can be used after applying patch 4/6 from this series, "SoC Camera: add support for g_parm / s_parm operations". Created and tested against linux-2.6.36-rc5 on Amstrad Delta. Signed-off-by:

This is a V4L2 driver for TI OMAP1 SoC camera interface. Both videobuf-dma versions are supported, contig and sg, selectable with a module option. The former uses less processing power, but often fails to allocate contignuous buffer memory. The latter is free of this problem, but generates tens of DMA interrupts per frame. If contig memory allocation ever fails, the driver falls back to sg automatically on next open, but still can be switched back to contig manually. Both paths work stable for me, even under heavy load, on my OMAP1510 based Amstrad Delta videophone, that is the oldest, least powerfull OMAP1 implementation. The interface generally works in pass-through mode. Since input data byte endianess can be swapped, it provides up to two v4l2 pixel formats per each of several soc_mbus formats that have their swapped endian counterparts. Boards using this driver can provide it with the following platform data: - if and what freqency clock is expected by an on-board camera sensor, - what is the maximum pixel clock that should be accepted from the sensor, - what is the polarity of the sensor provided pixel clock, - if the interface GPIO line is connected to a sensor reset/powerdown input and what is the input polarity. Created and tested against linux-2.6.36-rc5 on Amstrad Delta. Signed-off-by:
