This reverts commit cdaf9af1eaeb539e32bfd6da6310b41ad6c3ba23 which breaks I2S support on the non-DT Samsung SoC platforms, since the default "tx", "rx" DMA channel names for playback and capture streams or custom channel names in struct snd_dmaengine_pcm_config are supported in the ASoC dmaengine module only for devicetree booting case.

2016-12-31ASoC: samsung: i2s: Move saving and restoring regs to runtime pm operationsMarek Szyprowski1-14/+12
This patch moves saving and restoring I2S registers to runtime PM operations, what prepares the driver to operate with audio power domain. When support for audio power domain is enabled and the domain is being turned off, the I2S module will loose its context (registers), so runtime callbacks have to handle it. System sleep suspend/resume operation are implemented on top of runtime PM operations with generic pm_runtime_force_suspend/resume helpers.

2016-12-31ASoC: samsung: i2s: Ensure proper runtime PM state of I2S deviceMarek Szyprowski1-8/+46
This patch adds calls to pm_runtime_get/put to ensure that any access to I2S registers is done with proper (active) runtime PM state of I2S device. Till now the driver enabled runtime PM, but didn't manage the state during driver operation. The driver worked fine only because the runtime PM callbacks managed device clock, which was enabled all the time because of the additional enable call in the driver's probe function.

2016-12-31ASoC: samsung: i2s: Remove virtual device for secondary DAIMarek Szyprowski1-76/+26
For some unknown (maybe historical?) reasons support for secondary I2S DAI was implemented by adding additional virtual platform device, which was then probed again with the main I2S driver. This pattern is really hard to follow and provides no benefits, so lets remove this hack and register both DAIs during linear probe of Exynos I2S controller driver.

2016-12-15ASoC: samsung: Remove tests of member addressKrzysztof Kozlowski1-8/+2
The driver was checking for non-NULL address of struct's members: - s3c_audio_pdata->type (union), - s3c_audio_pdata->type.i2s (embedded struct). This is pointless as these will be always non-NULL. The 's3c_audio_pdata' is always initialized in static memory so it will be zeroed. Additionally the 'type' member was an union with only one member. It is safe to reorganize the structures to get rid of useless union and checks for addresses to fix the coccinelle warning: >> sound/soc/samsung/i2s.c:1270:2-4: ERROR: test of a variable/field address Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Reviewed-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2016-10-28ASoC: samsung: get access to DMA engine early to defer probe properlyMarek Szyprowski6-45/+47
ASoC Samsung sub-drivers tried to get access to their DMA engine controllers as a last step in driver probe. If a DMA engine was not available yet, samsung_asoc_dma_platform_register() function ended in -EPROBE_DEFER, but the driver already registered its component to ASoC core. This patch moves samsung_asoc_dma_platform_register() call before registering any components, to the common place, where driver was gathering all needed resources. In case of Samsung Exynos i2s driver the issue was even worse. The driver managed already to register its secondary DAI platform device before even getting the DMA engine access. That together with -EPROBE_DEFER error code from samsung_i2s_probe() immediately triggered another round of deferred probe retry and in turn endless loop of driver probing. This patch fixes broken boot on Odroid XU3 and other Exynos5422-based boards.
