git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC multiplatform code updates from Arnd Bergmann: "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only. Both of these platforms are now multiplatform. Finally, a couple of patches from Russell for Dove PMU, and a fix from Valentin Rothberg for Exynos ADC, which were rebased on top of the series to avoid conflicts" * tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (75 commits) ARM: realview: don't select SMP_ON_UP for UP builds ARM: s3c: simplify s3c_irqwake_{e,}intallow definition ARM: s3c64xx: fix pm-debug compilation iio: exynos-adc: fix irqf_oneshot.cocci warnings ARM: realview: build realview-dt SMP support only when used ARM: realview: select apropriate targets ARM: realview: clean up header files ARM: realview: make all header files local ARM: no longer make CPU targets visible separately ARM: integrator: use explicit core module options ARM: realview: enable multiplatform ARM: make default platform work for NOMMU ARM: debug-ll: move DEBUG_LL_UART_EFM32 to correct Kconfig location ARM: defconfig: use correct debug_ll settings ARM: versatile: convert to multi-platform ARM: versatile: merge mach code into a single file ARM: versatile: switch to DT only booting and remove legacy code ARM: versatile: add DT based PCI detection ARM: pxa: mark ezx structures as __maybe_unused ARM: pxa: mark raumfeld init functions as __maybe_unused ...

2015-12-01ASoC: samsung/smartq: use dynamic registrationArnd Bergmann1-50/+26
As a prerequisite for moving s3c64xx into multiplatform configurations, we need to change the smartq audio driver to stop using hardcoded gpio numbers from the header file, and instead pass the gpio data through platform_data. In order to do that, we also move the code to use module_platform_driver and register the platform device using platform_device_register_simple and register the gpios through the gpiod API.

2015-11-21ASoC: samsung: pass filter function as pointerArnd Bergmann9-25/+33
As we are now passing the filter data as pointers to the drivers, we can take the final step and also pass the filter function the same way. I'm keeping this change separate, as there it's less obvious that this is a net win. Upsides of this are: - The ASoC drivers are completely independent from the DMA engine implementation, which simplifies the Kconfig logic and in theory allows the same sound drivers to be built in a kernel that supports different kinds of dmaengine drivers. - Consistency with other subsystems and drivers On the other hand, we have a few downsides: - The s3c24xx-dma driver now needs to be built-in for the ac97 platform device to be instantiated on s3c2440. - samsung_dmaengine_pcm_config cannot be marked 'const' any more because the filter function pointer needs to be set at runtime. This is safe as long we don't have multiple different DMA engines in thet same system at runtime, but is nonetheless ugly.

Vendor drivers no longer access a DAI link's runtime by the link index but by matching the link name via snd_soc_get_pcm_runtime(). We assume each DAI link has a unique name.

2015-11-18ASoC: s3c24xx-i2s: pass DMA channels as platform dataArnd Bergmann2-4/+20
This is a minor cleanup to make the s3c2412-i2s and s3c24xx-i2s drivers independent of the mach/dma.h header file and to allow removing the dependency on the specific dmaengine driver in the next patch. As a side not, only the s3c24xx-i2s driver seems to still be used, while the definition of the s3c2412-i2s platform device was removed in commit 6d259a25b56d ("ARM: SAMSUNG: use static declaration when it is not used in other files") after it had never been referenced since its introduction in f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support"). Apparently it should have been used by mach-jive.c, but that never happened. My patch at this point leaves the current state unchanged, we can decide whether to fix or delete the jive driver and s3c2412-i2s another time.

2015-11-18ASoC: samsung: pass DMA channels as pointersArnd Bergmann8-73/+23
ARM64 allmodconfig produces a bunch of warnings when building the samsung ASoC code: sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data': sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] playback_data->filter_data = (void *)playback->channel; sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] capture_data->filter_data = (void *)capture->channel; We could easily shut up the warning by adding an intermediate cast, but there is a bigger underlying problem: The use of IORESOURCE_DMA to pass data from platform code to device drivers is dubious to start with, as what we really want is a pointer that can be passed into a filter function. Note that on s3c64xx, the pl08x DMA data is already a pointer, but gets cast to resource_size_t so we can pass it as a resource, and it then gets converted back to a pointer. In contrast, the data we pass for s3c24xx is an index into a device specific table, and we artificially convert that into a pointer for the filter function.

regmap is a library function that gets selected by drivers that need it. No driver modules should depend on it, since this can create dependency loops. E.g. if machine driver depends on REGMAP_I2C and selects the CODEC driver and the CODEC driver selects REGMAP_I2C, then the machine driver selects by extension one of its dependencies. The proper way to handle this is for machine drivers to depend on the same dependencies as the CODEC driver they select. In this case it is I2C.

2015-01-14ASoC: samsung: i2s: Add clock provider for the I2S internal clocksSylwester Nawrocki1-20/+93
This patch adds clock provider (currently only for DT platforms) for the CODECLKO (CDCLK) gate, RCLKSRC mux and RCLK pre-scaler divider divider clock. Those all tree clock are only available in the IIS Multi Audio Interface (I2S0), the regular IIS Bus Interface has only CDCLK gate clock. The motivation behind this patch is to expose the I2S internal clocks which are currently controlled through set_sysclk() through the clk API, so dedicated sound machine driver per each board can be avoided. The intention is also to fix the CDCLK gating issue reported by Daniel Drake: http://mailman.alsa-project.org/pipermail/alsa-devel/2014-September/081753.html This patch also reverts commit b97c60abf9a561f86ae71bd741add02673cc1 ("ASoC: samsung-i2s: Maintain CDCLK settings across i2s_{shutdown/ startup}") The problem that commit attempted to solve only affects the Odroid X2/U3, which doesn't configure the CDCLK clock in struct snd_soc_dai_ops hw_params callback and the issue should be now resolved by using clk API, i.e. having the codec enabling/ disabling the CDCLK clock as required.

The clk_prepare_enable() call on the "iis" clock is moved to happen earlier in the DAI platform device driver's probe() callback, so the I2S registers can be safely accessed through the clk API, after the clk supplier is registered in the platform device probe(). After this patch the "iis" clock is kept enabled since the (primary) I2S platform device probe() and until the platform device driver remove() call. This is similar to gating the clock in the snd_soc_dai probe() and remove() callbacks. Normally, in addition to that we should mark the device as PM runtime active, so if runtime PM is enabled it can idle the device by turning off the clock. Correcting this issue is left for a separate patch series, as we need to ensure the BUSCLK clock is always enabled when required.
