6938083e4f iPod Video: Fix playback after recording (FS #7402). Implement recording gain adjustment. * Enable timeout for zero-crossing detection (SLOWCLK), avoids hanging volume/ gain due to DC offsets.

2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

06a5299aff Do some crackdown on kernel object reinitialization after they could be in use and use before initialization. For c200/e200: Be sure fat cache and ata locks are acquired in the proper order during hot swapping. Delay hotswap monitoring until after initial file mounting (address 2nd kobj concern + possible call of fat driver before init).

054447f9e6 Commit FS#8379 by Andree Buschmann. Disables much of the remaining unneeded hardware on PP50xx targets (Ipods, Sansa, H10s, etc) resulting in a large savings in power and consequent increase in battery life. Results vary from target to target and from codec to codec, but we now approach the OF runtime on several PP devices. For now, leave base CPU clock at 30MHz, although further savings is possible with some codecs if clock is reduced. Additionally, fix battery capacity on c200 and use my measurements to improve runtime estimation for Sandisk targets.

47cfed1f1b audio on the m:robe 100 
- using the existing wm8751 driver (from gigabeat port) integrated into the portal player environment
- only 44.1kHz at the moment
- for some reason the output is very quiet
- due to the lack of usable buttons the easiest (?) way to start an audio file is to copy the .playlist_control, config.cfg and nvram.bin files from another target, where auto resume is enabled.

91bacf363a Get rid of a couple of inl/outl since we have defines. Also use some other defines in place of magic values.

1d1a17c0db Improved H10 ADC driver. We now do things exactly as the OF does. This includes shifting the readings by 0x14 when PLL is enabled. Battery voltages and remote/scrollpad values adjusted accordingly. We also now wait for the ADC to indicate the conversion is complete before reading the data, so hopefully we will get more reliably steady readings.

15b7321fe1 Split wm8731 and wm8721 drivers. wm8721 can be much simpler since it has no recording. Provide reg bit definitions for those. Add some temporary hacks pcm-pp to prevent crashing when playing after recording. Make playback start after recording on pp5020. Get wm8731 to monitor recording but plans are to do that digitally.

018d555995 Sound working on iPod 2nd gen, but very unstable (applies also to 3rd gen). Freezes most of the time. Reverting the >66MHz unlock makes it a bit better, but also not stable. Using the C FIQ has the same effect.

fe23dc8f15 Improved CPU clock setup for PP502x. PP5020 and PP5022 are not register compatible here, so define the PP5022 targets properly, and introduce a CPU_PP502x macro for easier family check. Improves stability on PP5020 (less freezing, tested with Mini G1) and reduces clock change penalty (500us on PP5020; uses the relock bit on PP5022).

5d63776a24 Reenable aynchronous audio init stage. Really just single stage with aynchronous enabling of outputs. Keeps audio_init last so prior init steps can use the audiobuffer in any desired way. Audio will be fully initialized by the time the UI is entered. Playback of voice or audio will be delayed properly until audio hardware is ready.
