Added entry into usbquirks.h to recognize Roland SonicCell sound module by mostly duplicating the entry for the Roland SH-201. USB MIDI works just fine, though the USB audio is a little unreliable (but still works well enough). Signed-off-by:

The VT1724 MIDI port is not MPU-401 compatible; remove the hacks that try to make the MPU-401 library work with it, and just use some simple device-specific code. Signed-off-by:

When timer ticks are disabled when calling sound/soc/s3c24xx/s3c24xx-i2s.c:s3c24xx_snd_lrsync and the LR signal never happens, we loop forever. This has been observed in the following call chain: snd_pcm_common_ioctl1 -> snd_pcm_action_lock_irq -> snd_pcm_action_single -> snd_pcm_do_resume -> soc_pcm_trigger -> s3c24xx_i2s_trigger The patch below changes the timeout mechanism to use udelay, which doesn't need timer ticks.

Currently the ASoC core configures the bias levels in the system using a callback on codecs and machines called 'dapm_event', passing it PCI style power levels as SNDRV_CTL_POWER_ constants. This is more obscure than it needs to be and has caused confusion to driver authors, especially given that DAPM is also performing power management. Address this by renaming the callback function to 'set_bias_level' and using constants explicitly representing the off, standby, pre-on and on states which DAPM transitions through. Also unexport the API for setting bias level: there are currently no in-tree users of this API other than the core itself and it is likely that the core would need to be extended to cater for any users.

The CPU and codec DAI operations differ only in the presence of the digital mute operation for the codec so they may as well be the same type. Signed-off-by:

Many HD-audio controllers seem inaccurate about the IRQ timing of PCM period updates. This has caused problems on audio quality; e.g. JACK doesn't work with two periods. This patch fixes the problem by checking the current DMA position at IRQ handler and delays the period-update via a workq if it's inaccurate. Signed-off-by:

- figured out 'Digital(ly) Enhanced Game Port' functionality, implemented support for it (eliminating gameport polling overhead) - removed optional joystick activation, gameport now enabled unconditionally, since we now support it via the PCI I/O space, not via conflict-prone legacy I/O (which I was thus able to DISABLE now)! - fix playback bug (a muted wave output would get unmuted upon start of playback, of course this is not what we want, thus remember mute state) - implement partial power management: when idle, lower clock rate and disable codec (reduced noise!), and disable gameport circuit when unused - instantiate OPL3 timer, too - much better implementation of snd_azf3328_mixer_write_volume_gradually() - slightly optimized interrupt handling - lots of cleanup This time, I also found a way to verify proper OPL3 operation via MIDI file playback (emulation via synth hardware).

ASoC codecs and machine drivers that use DAPM routes all cut'n'paste a loop iterating over a null terminated array of routes. Factor out this into a bulk registration function, improving the error reporting for most users, and deprecate the old API to help out of tree users pick up the changes. Signed-off-by:

This patch adds support for AIC3x GPIO lines. They can be configured for many possible functions as well as be driven manually. I also introduced i2c read functionality since the GPIO state register has to be read from hardware every time and can not be served from cache. Signed-off-by:

This patch cleans up the clocking setup for aic3x codecs. It drops the dividers table and determines the PLL control values programatically. Under certain conditions, the PLL is disabled entirely which could save some power. Signed-off-by:
