2009-08-20ASoC: OMAP: Use DMA operating mode of McBSPEduardo Valentin1-3/+15
Configures DMA sync mode depending on McBSP operating mode value. The value is configurable by McBSP instance. So, depending on McBSP operating mode, the DMA sync mode is passed from omap-mcbsp to omap-pcm. Besides that, it also configures McBSP threshold value depending on which McBSP mode is activated.

2009-08-20ASoC: OMAP: Use McBSP threshold to playback and captureEduardo Valentin3-7/+49
This patch changes the way DMA is done in omap-pcm.c in order to reduce power consumption. There is no need to have so much SW control in order to have DMA in idle state during audio streaming. Configuring McBSP threshold value and DMA to FRAME_SYNC are sufficient.

2009-08-20ASoC: Always syncronize audio transfers on framesEero Nurkkala1-0/+9
All these steps are required for ASoC to behave correctly. rccr and xccr are format dependent, for example TDM audio has different values than I2S or DSP_A. Also the omap_mcbsp_xmit_enable and/or omap_mcbsp_recv_enable must be called right after the DMA has started. This provides no longer L and R channels switching at random.

2009-08-20ALSA: pcm - Fix drain behavior in non-blocking modeTakashi Iwai2-27/+37
The current PCM core has the following problems regarding PCM draining in non-blocking mode: - the current f_flags isn't checked in snd_pcm_drain(), thus changing the mode dynamically via snd_pcm_nonblock() after open doesn't work. - calling drain in non-blocking mode just return -EAGAIN error, but doesn't provide any way to sync with draining. This patch fixes these issues. - check file->f_flags in snd_pcm_drain() properly - when O_NONBLOCK is set, PCM core sets the stream(s) to DRAIN state but quits ioctl immediately without waiting the whole drain; the caller can sync the drain manually via poll() Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-08-20ibm_newemac: emac_close() needs to call netif_carrier_off()Petri Gynther1-0/+2
When ibm_newemac netdev instance is shutdown with "ifconfig down", the netdev interface does not go properly down. netif_carrier_ok() keeps returning TRUE even after "ifconfig down". The problem can be seen when ibm_newemac instances are slaves of a bonding interface. The bonding interface code uses netif_carrier_ok() to determine the link status of its slaves. When ibm_newemac slave is shutdown with "ifconfig down", the bonding interface won't detect any link status change because netif_carrier_ok() keeps returning TRUE.

2009-08-19ALSA: hda - Fix probe of Toshiba laptops with ALC268 codecTakashi Iwai1-2/+13
There are many variants of Toshiba laptops with ALC268 codec, and it seems that a few of them don't work with model=toshiba preset since they have the secondary ALC268 codec just for HDMI output. This is a regression due to the previous clean-up work to merge all Toshiba quirk entries into a single check. This patch adds the identification of such laptops to apply the standard BIOS-probing method. Unfortunately, Toshiba laptops have all the same PCI SSID, so we need to check the codec SSID to identify each device.

2009-08-19clockevent: Prevent dead lock on clockevents_lockSuresh Siddha4-17/+18
Currently clockevents_notify() is called with interrupts enabled at some places and interrupts disabled at some other places. This results in a deadlock in this scenario. cpu A holds clockevents_lock in clockevents_notify() with irqs enabled cpu B waits for clockevents_lock in clockevents_notify() with irqs disabled cpu C doing set_mtrr() which will try to rendezvous of all the cpus. This will result in C and A come to the rendezvous point and waiting for B. B is stuck forever waiting for the spinlock and thus not reaching the rendezvous point. Fix the clockevents code so that clockevents_lock is taken with interrupts disabled and thus avoid the above deadlock. Also call lapic_timer_propagate_broadcast() on the destination cpu so that we avoid calling smp_call_function() in the clockevents notifier chain. This issue left us wondering if we need to change the MTRR rendezvous logic to use stop machine logic (instead of smp_call_function) or add a check in spinlock debug code to see if there are other spinlocks which gets taken under both interrupts enabled/disabled conditions.

2009-08-19sparc32: Kill trap table freeing code.David S. Miller2-48/+0
Normally, srmmu uses different trap table register values to allow determination of the cpu we're on. All of the trap tables have identical content, they just sit at different offsets from the first trap table, and the offset shifted down and masked out determines the cpu we are on. The code tries to free them up when they aren't actually used (don't have all 4 cpus, we're on sun4d, etc.) but that causes problems. For one thing it triggers false positives in the DMA debugging code. And fixing that up while preserving this relative offset thing isn't trivial. So just kill the freeing code, it costs us at most 3 pages, big deal... Signed-off-by: David S. Miller <davem@davemloft.net>
