The problem is that snd_hda_get_connections() returns out-of-range result for NID 0x1c (something like 0xf8f9 or 0xffff). This patch adds a check to alc880_parse_auto_config() to avoid using of this out-of-range NIDs. A better fix maybe to improve snd_hda_get_connections() routine to check for valid NID ranges if NIDs are expected as result.

Unfortunately, the descriptors of that altsetting have a wrong channel setting, which means that any recorded data from such a device has twice the sample rate from what would be expected. This patch adds a workaround to ignore that altsetting. Since these devices have only one actual channel, no data is lost.

This screws up the recent PCM core code that tries to correct the position based on the irq timing. Now, when a backward irq position is detected, skip the update instead of rebasing. (This is almost the old behavior before 2.6.30.)

This patch enables the PLL when it is used. Additionally, it disables the PLL when it is bypassed. Without this patch, the audio on TI DM646x EVM and DM355 EVM does not work properly. The bit clocks and the frame sync signals from the codec are not correct and hence the playback/record are faster than usual for most sample rates. The reason for this was that the PLL was not enabled when it was not bypassed. Tested on DM6467 EVM, playback tested on DM355 EVM.
