2013-12-12ASoC: samsung: Provide helper for DMA initMark Brown
In preparation for using the dmaengine helpers in ASoC rather than the dmaengine wrappers for the Samsung API wrap the configuration of dma_data. The dmaengine code expects different data to that used by the legacy API. Signed-off-by: Mark Brown <broonie@linaro.org>

2013-10-25ASoC: samsung: fix return value check in i2s_alloc_dai()Wei Yongjun
In case of error, the function platform_device_alloc() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-08-13ASoC: Samsung: I2S: Modify the I2S driver to support I2S on Exynos5420Padmavathi Venna
Exynos5420 added support for I2S TDM mode. For this, there are some register changes in the I2S controller. This patch adds the relevant register changes to support I2S in normal mode. This patch adds a quirk for TDM mode and if TDM mode is present all the relevent changes will be applied.

2013-08-13ASoC: Samsung: I2S: Add quirks as driver data in I2SPadmavathi Venna
Samsung has different versions of I2S introduced in different platforms. Each version has some new support added for multichannel, secondary fifo, s/w reset control and internal mux for rclk src clk. Each newly added change has a quirk. So this patch adds all the required quirks as driver data and based on compatible string from dtsi fetches the quirks.

2013-04-03ASoC: Samsung: set drvdata before adding secondary devicePrathyush K
Currently, a new platform device is created for secondary device by calling platform_device_register_resndata and then the drvdata is set for this device. The following patch has been added to driver core: "driver core: fix possible missing of device probe". This results in the added device getting probed immediately but the drvdata for the secondary device is not yet set. This patch removes the platform_device_register_resndata call and instead calls platform_device_alloc, platform_set_drvdata and platform_device_add which fixes the above issue.

2012-12-07ASoC: Samsung: Do not register samsung audio dma device as pdevPadmavathi Venna
Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a platform_device. This didn't represent the hardware well, since there was no separate hardware associated with this platform_device; it was a virtual device with sole purpose to call snd_soc_register_platform(). This change removes the platform_device completely. Each Samsung DAI now registers the ASoC 'platform' itself. Machine drivers are adjusted for the new 'platform' name.

2011-11-23ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether. The patch was generated with the following coccinelle semantic patch: // <smpl> @@ identifier ops; @@ -struct snd_soc_dai_ops ops = +const struct snd_soc_dai_ops ops = { ... }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
