2013-10-23ASoC: tegra: Remove redundant initialisation of compat_filter_fnMark Brown
Setting a field in a static struct to NULL has no effect so don't bother (and don't generate false positives for grep). Signed-off-by: Mark Brown <broonie@linaro.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Stephen Warren <swarren@nvidia.com>
2013-10-23ASoC: ep93xx: Open code dma channel requestMark Brown
Currently the ep93xx DMA code is one of the few users relying on the fact that the compat code uses the dma_data as the filter data for non-DT channel requests. Since the rest of the core expects this to be a struct snd_dmaengine_dai_data this isn't terribly helpful this will be changed to use the already existing filter data so avoid breaking ep93xx by open coding the current behaviour.

2013-10-23ASoC: davinci-mcasp: Remove redundant num-serializer DT parameterPeter Ujfalusi
The serial-dir array gives this information so there is no need to have the num-serializer property in DT description. Just ignore the property in the driver the DTS files can be updated separately without regression.

2013-10-23ASoC: davinci-mcasp: Improve DT bindings documentJyri Sarha
Makes interrupts property optional as the interrupts are not currently used by the driver and adds interrupt-names property to name listed interrupts. Currently know interrupt names are "tx" and "rx". - Improve tdm-slots propery description - Improve op-mode property description - Add pinctrl-names and pinctrl-0 properties - Remove #address-cells and #size-cells as they are not needed. - Bracket named interrupts property tuples for uniformity. - Add missing "for" to serial-dir prop in DT bindings doc.

2013-10-22ASoC: davinci-mcasp: Add location for data port registers to DTJyri Sarha
This patch adds a separate register location for data port registers to mcasp DT bindings. On am33xx SoCs the McASP registers are mapped trough L4 interconnect, but data port registers are also mapped trough L3 bus to a different memory location.

2013-10-22ASoC: dont call dapm_sync while reporting jack alwaysVinod Koul
While reporting the jack status snd_soc_jack_report() invokes snd_soc_dapm_sync() always. This should be required when we have pins associated with jack and reporting enables or disables these.

2013-10-20ASoC: si476x: Fix locking of coreMark Brown
The conversion of the si476x to regmap removed locking of the core during register updates, allowing things like power state changes for the MFD to happen during a register update. Avoid this by taking the core lock in the DAI operations (which are the only things that do register updates) as we used to do in the open coded register I/O functions.

2013-10-20ASoC: kirkwood: prefer external clock over internal clockJean-Francois Moine
When there is an external clock, always use this one. This prevents the two Dove audio devices to use the same DCO clock at different rates. Signed-off-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-10-20ASoC: rcar: remove RSND_SSI_CLK_FROM_ADGKuninori Morimoto
R-Car sound has clock pin for each SSI, and sometimes, these pins are shared with paired SSI. It may sometimes become "SSI-A clock pin is master" and "SSI-B clock pin is slave", but "SSI-A/B clock pins are shared". SSI-B needs SSI-A clock in this case. Current R-Car sound driver is using RSND_SSI_xxx flag to control this kind of shared pin behavior. But, this information, especially clock master setting, can be got from ASoC set_fmt settings. This patch removes rsnd_ssi_mode_init() and extend rsnd_ssi_mode_set() to controlling pin settings via .set_fmt. This patch doesn't removes RSND_SSI_CLK_FROM_ADG flag at this point to avoid conflict branch merging between ASoC <-> SH-ARM.

2013-10-20ASoC: rcar: add rsnd_scu_hpbif_is_enable()Kuninori Morimoto
Current SSI needs RSND_SSI_DEPENDENT flag to decide dependent/independent mode. And SCU needs RSND_SCU_USE_HPBIF flag to decide HPBIF is enable/disable. But these 2 means same things. This patch adds new rsnd_scu_hpbif_is_enable() function, and merges above methods. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-10-20ASoC: simple-card: un-implemented set_fmt is not errorKuninori Morimoto
Current simple-card returns error if DAI doesn't support .set_fmt callback. But the error is -ENOTSUPP (= not supported), and it is not error. This patch avoids such case Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-10-20ASoC: dai: Provide interface for setting DMA data at probe timeMark Brown
Allow DMA data to be set at probe time for devices that can do that, avoiding the need to do it every time we start a stream and supporting non-DT dmaengine users using the helpers. Signed-off-by: Mark Brown <broonie@linaro.org>
2013-10-19ASoC: dmaengine-pcm: Provide default configLars-Peter Clausen
This patch adds some default settings for the generic dmaengine PCM driver for the case that no config has been supplied. The following defaults are used: * Use snd_dmaengine_pcm_prepare_slave_config for preparing the DMA slave config. * 512kB for the prealloc buffer size. This value has been chosen based on 'feels about right' and is not backed up by any scientific facts. We may need to come up with something smarter in the future but it should work fine for now. With this infrastructure in place we can finally write DAI drivers which are independent of the DMA controller they are connected to. This is e.g. useful if the DAI IP core is reused across different SoCs, but the SoCs uses different DMA controllers.

2013-10-19ASoC: dmaengine-pcm: Add support for querying DMA capabilitiesLars-Peter Clausen
Currently each platform making use the the generic dmaengine PCM driver still needs to provide a custom snd_pcm_hardware struct which specifies the capabilities of the DMA controller, e.g. the maximum period size that can be supported. This patch adds code which uses the newly introduced dma_get_slave_caps() API to query this information from the dmaengine driver. The new code path will only be taken if the 'pcm_hardware' field of the snd_dmaengine_pcm_config struct is NULL. The patch also introduces a new 'fifo_size' field to the snd_dmaengine_dai_dma_data struct which is used to initialize the snd_pcm_hardware 'fifo_size' field and needs to be set by the DAI driver.

2013-10-19ASoC: rt5640: Don't go to standby on resumeMark Brown
There is no need for the CODEC to go to standby on resume since the core will power it up as needed and in any case it is an idle_bias_off CODEC so would normally sit with bias off while idle. Signed-off-by: Mark Brown <broonie@linaro.org> Tested-by: Stephen Warren <swarren@nvidia.com>
2013-10-19ASoC: rt5640: Power down LDO while suspendedMark Brown
If we have control over the LDO then disable it during suspend; the device is already being put into reset so will be non-functional over suspend anyway and this will save a small amount of power. Signed-off-by: Mark Brown <broonie@linaro.org> Tested-by: Stephen Warren <swarren@nvidia.com>
2013-10-19ASoC: cirrus: Enable compile test buildsMark Brown

2013-10-17usb: usb_phy_gen: refine conditional declaration of usb_nop_xceiv_registerGuenter Roeck
Commit 3fa4d734 (usb: phy: rename nop_usb_xceiv => usb_phy_gen_xceiv) changed the conditional around the declaration of usb_nop_xceiv_register from #if defined(CONFIG_NOP_USB_XCEIV) || (defined(CONFIG_NOP_USB_XCEIV_MODULE) && defined(MODULE)) to #if IS_ENABLED(CONFIG_NOP_USB_XCEIV) While that looks the same, it is semantically different. The first expression is true if CONFIG_NOP_USB_XCEIV is built as module and if the including code is built as module. The second expression is true if code depending on CONFIG_NOP_USB_XCEIV if built as module or into the kernel. As a result, the arm:allmodconfig build fails with arch/arm/mach-omap2/built-in.o: In function `omap3_evm_init': arch/arm/mach-omap2/board-omap3evm.c:703: undefined reference to `usb_nop_xceiv_register' Fix the problem by reverting to the old conditional.
