Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

V4L/DVB (3384): Separate tv & radio freqs, fix cb/freq transmit order for tuners that need this. - Moved MSP_SET_MATRIX to v4l2-common.h - Fix typos and integer overflows in tea5767.c - Split old freq field into a tv_freq and a radio_freq. Prevents that a radio tuner is initialized with a tv frequency or vice versa. - When switching to radio mode initialize the tuner with the last used radio frequency (this was already done for the TV mode). As a result of these changes the tuner module now remembers the last set radio and TV frequencies, which is what you would expect to happen. - Move out of range frequencies to the closest valid frequency as per v4l2 API spec. - Fix incorrect initial radio frequency (multiplier is 16000, not 16) - Add boundary check for out of range frequencies. - Use new flag to check if the order of the CB and freq. depends on the last set frequency. That is needed for some tuners or you can get static as a result. The flag is added for those tuners where I know that the datasheet indicates that this is necessary. - For this new check use the last set div value, not the last frequency as radio frequencies are always much higher due to the 16000 multiplier.
