2009-03-30V4L/DVB (11067): au0828: workaround a bug in the au0828 i2c handlingDevin Heitmueller
There is an issue related to the i2c clock for addressing the xc5000. The au0828 chip does not support clock stretching, which the xc5000 makes use of. This results in cases where we silently get back garbage in i2c read operations. To work around this issue until we slow down the i2c clock when talking with that specific device. This was not an issue before we had analog support because we never needed to enumerate the i2c bus, and digital tuning never actually needed to perform read operations against the xc5000.

2009-03-30V4L/DVB (11027): soc-camera: configure drivers with a default format at ↵Guennadi Liakhovetski
probe time Currently soc-camera doesn't set up any image format without an explicit S_FMT. According to the API this should be supported, for example, capture-example.c from v4l2-apps by default doesn't issue an S_FMT. This patch moves negotiating of available host-camera format translations to probe() time, and restores the state from the last close() on the next open(). This is needed for some drivers, which power down or reset hardware after the last user closes the interface. This patch also has a nice side-effect of avoiding multiple allocation anf freeing of format translation tables.
