2017-08-21ASoC: s3c24xx_uda134x: Remove unnecessary function callDonglin Peng1-1/+0
First of all,the address of pdev->dev is assigned to card->dev,then the function platform_set_drvdata copies the value the variable card to pdev->dev.driver_data, but when calling snd_soc_register_card,the function dev_set_drvdata(card->dev, card) will also do the same copy operation,so i think that the former copy operation can be removed.

2017-08-17ASoC: samsung: make snd_soc_ops constBhumika Goyal1-1/+1
Make these const as they are only stored in the ops field of a snd_soc_dai_link structure, which is const. Done using Coccinelle. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Reviewed-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>

Also unused ENFORCE_RATES symbol and local variable (leftovers from an erroneous rebase) are removed.

2016-08-04ASoC: samsung: Fix clock handling in S3C24XX_UDA134X cardSylwester Nawrocki1-3/+4
There is no "pclk" alias in the s3c2440 clk driver for "soc-audio" device so related clk_get() fails, which prevents any operation of the S3C24XX_UDA134X sound card. Instead we get the clock on behalf of the I2S device, i.e. we use the I2S block gate clock which has PCLK is its parent clock. Without this patch there is an error like: s3c24xx_uda134x_startup cannot get pclk ASoC: UDA134X startup failed: -2 Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-01-06ASoC: s3c24xx_uda134x: Use static DAI format setupLars-Peter Clausen1-10/+2
Set the dai_fmt field in the dai_link struct instead of manually calling snd_soc_dai_fmt(). This makes the code cleaner and shorter. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-10-20ASoC: samsung: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-04-11ASoC: samsung: move plat/ headers to local directoryArnd Bergmann1-1/+1
The plat/regs-iis.h and plat/regs-ac97.h files in the samsung platform are only needed by the ASoC drivers, so they can be moved into the same directory, as one more step towards a multiplatform build.

2012-12-07ASoC: Samsung: Do not register samsung audio dma device as pdevPadmavathi Venna1-1/+1
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.

2011-03-11ASoC: mini2440: Fix uda134x codec problem.Marek Belisko1-1/+2
ASoC audio for mini2440 platform in current kenrel doesn't work. First problem is samsung_asoc_dma device is missing in initialization. Next problem is with codec. Codec is initialized but never probed because no platform_device exist for codec driver. It leads to errors during codec binding to asoc dai. Next problem was platform data which was passed from board to asoc main driver but not passed to codec when called codec_soc_probe(). Following patch should fix issues. But not sure if in correct way. Please review.

2011-01-25ASoC: Samsung: Fix outdated cpu_dai_name for s3c24xx i2sLars-Peter Clausen1-1/+1
During the multi-component patch the s3c24xx i2s driver was renamed from "s3c24xx-i2s" to "s3c24xx-iis", while the sound board drivers were not updated to reflect this change as well. As a result there is no match between the dai_link and the i2s driver and no sound card is instantiated. This patch fixes the problem by updating the sound board drivers to use "s3c24xx-iis" for the cpu_dai_name.
