Added model=acer for ALC268 codec support. The configuration is: headphone = 0x14, speaker = 0x15 needs hp-jack auto-detection. The same routine as alc262-fujitsu model is used. Also, added the auto-muting routine for ALC268 model=toshiba. Signed-off-by:

When CME keyboards send a SysEx message (e.g. master volume), the USB packet uses a format different from the standard format. Parsing this packet according to the specification corrupts the SysEx message itself and can cause the following MIDI messages to be misinterpreted, too. This patch adds a workaround for this case.

In the power-saving mode, the suspend is done dynamically at power-down. So we don't have to call suspend stuff explicitly if it's already powered down. Signed-off-by:

isn't needed there. Upatched code uses: memset(info, 0, sizeof(info)); where 'info' is a pointer and therefore only first 4 bytes of 'info' gets cleared on a 32bit machine. Anyway looking at the code zeoring this memory region isn't needed at all because the snd_emu10k1_fx8010_info() function initializes all the 'info' fields on its own. So that's why this code works at all in its original form. This patch removes this redundant code. Also snd_emu10k1_fx8010_info() can't fail so lets save some bytes and change its return type to void. Signed-off-by:

Added CONFIG_SND_HDA_POWER_SAVE kconfig. It's an experimental option to achieve an aggressive power-saving. With this option, the driver will turn on/off the power of each codec and controller chip dynamically on demand. The patch introduces a new module option 'power_save'. It specifies the second of time-out for automatic power-down. As default, it's 10 seconds. Setting 0 means to suppress the power-saving feature. The codec may have analog-input loopbacks, which are usually represented by mixer elements such as 'Mic Playback Switch' or 'CD Playback Switch'. When these are on, we cannot turn off the mixer and the codec chip has to be kept on. For bookkeeping these states, a new codec-callback is introduced. For the bus-controller side, a new callback pm_notify is introduced, which can be used to turn on/off the contoller appropriately. Note that this power-saving might cause slight click-noise at power-on/off. Also, it might take some time to wake up the codec, and might even drop some tones at the very beginning. This seems to be the side-effect of turning off the controller chip. This turn-off of the controller can be disabled by undefining HDA_POWER_SAVE_RESET_CONTOLLER in hda_intel.c. Signed-off-by:

Added snd_hda_codec_amp_stereo() function that changes both of stereo channels with the same mask and value bits. It simplifies most of amp-handling codes. Signed-off-by:

So far, the driver looked the table of snd_kcontrol_new used for creating mixer elements and forces to call each of its put callbacks in PM resume code. This is too ugly and hackish. Now, the resume is simplified using the codec amp and command register caches. The driver simply restores the values that have been written in the cache table. With this simplification, most codec support codes don't require any special resume callback. Signed-off-by:

This patch adds the cache for codec command registers. snd_hda_codec_write_cache() and snd_hda_sequence_write_cache() do the write operations with caching, which values can be resumed via snd_hda_codec_resume_cache(). The patch introduces only the framework, and no codec code is using this cache yet. It'll be implemented in the following patch. Signed-off-by:
