2013-08-29ASoC: Samsung: Do not queue cyclic buffers multiple timesTomasz Figa
The legacy S3C-DMA API required every period of a cyclic buffer to be queued separately. After conversion of Samsung ASoC to Samsung DMA wrappers somebody made an assumption that the same is needed for DMA engine API, which is not true. In effect, Samsung ASoC DMA code was queuing the whole cyclic buffer multiple times with a shift of one period per iteration, leading to: a) severe memory waste - up to 13x times more DMA transfer descriptors are allocated than needed, b) possible memory corruption, because further cyclic buffers were out of the original buffers, due to the offset. This patch fixes this problem by making the legacy S3C-DMA API use the same semantics as DMA engine (the whole cyclic buffer is enqueued at once) and modifying users of Samsung DMA wrappers in cyclic mode to behave appropriately.

2013-08-29snd/hda: add runtime suspend/resume on optimus support (v4)Dave Airlie
Add support for HDMI audio device on VGA cards that powerdown to D3cold using non-standard ACPI/PCI infrastructure (optimus). This does a couple of things to make it work: a) add a set of power ops for the hdmi domain, and enables them via vga_switcheroo when we are a switcheroo controlled card. This just replaces the runtime resume operation so that when the card is in D3cold the userspace pci config space access via sysfs, the vga switcheroon runtime resume gets called first and it calls the GPU resume callback before calling the sound card runtime resume. b) standard ACPI/PCI stacks won't put a device into D3cold without an ACPI handle, but since the hdmi audio devices on gpus don't have an ACPI handle, we need to manually force the device into D3cold after suspend from the switcheroo path only. c) don't try and do runtime s/r when the GPU is off. d) call runtime suspend/resume during switcheroo suspend/resume this is to make sure the runtime stack knows to try and resume the hdmi audio device for pci config space access. v2: fix incorrect runtime call suspend->resume. v3: rework irq handler to avoid false irq when we are resuming but haven't runtime resumed yet, don't bother trying D3cold, it won't work, just set it manually ourselves, move runtime s/r calls outside the main s/r hook. enable dnyamic pm properly by dropping reference. v4: put back irq handler check just wrap it with cap check Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
2013-08-28ALSA: opti9xx: Fix conflicting driver object nameTakashi Iwai
The recent commit to delay the release of kobject triggered NULL dereferences of opti9xx drivers. The cause is that all snd-opti92x-ad1848, snd-opti92x-cs4231 and snd-opti93x drivers register the PnP card driver with the very same name, and also snd-opti92x-ad1848 and -cs4231 drivers register the ISA driver with the same name, too. When these drivers are built in, quick "register-release-and-re-register" actions occur, and this results in Oops because of the same name is assigned to the kobject. The fix is simply to assign individual names. As a bonus, by using KBUILD_MODNAME, the patch reduces more lines than it adds. The fix is based on the suggestion by Russell King.

2013-08-27ASoC: Pass card instead of dapm context to snd_soc_dapm_new_widgets()Lars-Peter Clausen
snd_soc_dapm_new_widgets() works on the ASoC card as a whole not on a specific DAPM context. The DAPM context that is passed as the parameter is only used to look up the pointer to the card. This patch updates the signature of snd_soc_dapm_new_widgets() to take the card directly. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-08-27ASoC: Move call to snd_soc_dapm_new_widgets() after ↵Lars-Peter Clausen
snd_soc_dapm_auto_nc_codec_pins() Call snd_soc_dapm_new_widgets() before the auto non-connected pins have been marked as not connected will power the system under the assumption that those pins are connected. Once the pins have been marked as disconnected the system there will be an additional power run. This can cause unnecessary power transitions. Calling snd_soc_dapm_new_widgets() only after the pins have been marked as non-connected avoids this.

2013-08-27ASoC: Call snd_soc_dapm_new_widgets() only once during card initializationLars-Peter Clausen
Each time snd_soc_dapm_new_widgets() is called it will instantiate all the widgets and routes that have been added so far and then power them. Doing this multiple times before the card is fully initialized and all widgets have been added can cause unnecessary and even invalid power state transitions which can result in extra register writes and and also might cause clicks and pops.

2013-08-27ASoC: wm8904: Remove unnecessary call to snd_soc_dapm_new_widgets()Lars-Peter Clausen
The core will call snd_soc_dapm_new_widgets() once all components of the card have been initialized, so there is no need to do this manually in the driver. Calling it earlier also might result in a partially instantiated system being powered up which cause undesired side effects.

This patch adds flags and routines to get device list & selection info on a pin. To support Display Port 1.2 multi-stream transport (MST) over single DP port, a pin can support multiple devices. Please refer to HD-A spec Document Change Notificaton HDA040-A. A display audio codec can set flag "dp_mst" in its patch, indicating its pins can support MST. But at runtime, a pin may not be multi-streaming capable and report the device list is empty, depending on Gfx driver configuration.

2013-08-23i2c: move OF helpers into the coreWolfram Sang
I2C of helpers used to live in of_i2c.c but experience (from SPI) shows that it is much cleaner to have this in the core. This also removes a circular dependency between the helpers and the core, and so we can finally register child nodes in the core instead of doing this manually in each driver. So, fix the drivers and documentation, too. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
