* ASoC: ux500: Don't set unused struct snd_pcm_hardware fieldsLars-Peter Clausen2014-01-09
| | | | | | | | | | | The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.

* ASoC: ux500: Dramatically reduce the size of the DAI driver data structLee Jones2014-01-07
| | | | | | | | | | | We no longer have a means to differentiate between MSP devices at probe time, mainly because we don't really have to. So rather than have an over- sized static data structure in place, where the only difference between devices is the ID and name (which are unused), we'll just create one succinct, statically assigned and shared one instead.

* ASoC: ux500_pcm: Differentiate between pdata and DT initialisationLee Jones2014-01-07
| | | | | | | | | | | | If booting with full DT support (i.e. DMA too, the last piece of the puzzle), then we don't need to use the compatible_request_channel call back or require some of the historical bumph which probably isn't required by a platform data start-up now either. This will also be ripped out in upcoming commits. Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

* ASoC: ux500: Store DMA data in the DAI differently in the pdata and DT caseLee Jones2014-01-07
| | | | | | | | | | | | In this patch we do two things. Firstly, instead of open coding the store of DMA data in to the DAI for later use, we use the API provided. Secondly we create and store similar DMA data for the DT case, only this time we use 'struct snd_dmaengine_dai_dma_data' which is provided by the core for this very reason.

* ASoC: ux500_pcm: Extend Device Tree support to deal with DMA dataLee Jones2014-01-07
| | | | | | | | | | | | | Soon we will strip out pdata support from the Ux500 set of ASoC drivers. When this happens it will have to supply a DMA slave_config to the dmaengine. At the moment a great deal of this comes from pdata via AUXDATA. We need to become independent of this soon. This patch starts the process by allocating memory for the associated data structures and fetches the MSP id used for const struct indexing.

* ASoC: ux500_pcm: Expect different saved DMA data when obtaining from DAI storeLee Jones2014-01-07
| | | | | | | | | | | | | | | In preparation for full Device Tree enablement we must differentiate between the two varying ways DMA data can be held in the DAI store. If we're booting with Device Tree the provided 'snd_dmaengine_dai_dma_data' data structure shall be used, whereas in order to avoid breaking legacy platform data we also need to be able to translate DMA data stored using the UX500 specific 'ux500_msp_dma_params' method. Once we move over to solely use Device Tree, we can enforce the use of 'snd_dmaengine_dai_dma_data' and this code can be removed altogether.

* ASoC: ux500_pcm: Stop pretending that we support varying address widthsLee Jones2014-01-07
| | | | | | | | | | | The Slave Config's addr_width attribute is populated by data_width of dma_cfg, which in turn is derived from dma_params' data_size attribute and that comes from the slot_width which is always 16 bits (2 Bytes). We're cutting out the middle man here and just setting the DMA Slave Config directly. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: Ux500: Match platform by device node when booting Device TreeLee Jones2014-01-07
| | | | | | | | | | | We're getting closer to fully enabling the Ux500 ASoC driver for Device Tree. When we switch over from using AUXDATA we'll need to match platform by only Device Tree nodes. In this patch we NULL out the platform_name, and supply nodes for each platform device.

| | | | | | | | | | These drivers will not work without platform specific data, which is passed in via Device Tree or Platform Data. To avoid the chance of NULL pointer dereferencing and alike, let's ensure we have at least one of the methods in play before continuing.

At that point, snd_hda_power_down() notifies the power down to the controller, and this may confuse the refcount if the codec was already powered up before the resume. In the end result, the controller goes to runtime suspend even before the codec is kicked off to the power save, and the communication stalls happens. The fix is to add the power-up notification together with hda_keep_power_on(), and clears the flag appropriately. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

First attempt at fixing it would have led to a race, so this undoes the device_createa work and does it all manually making sure the dev->type is setup before we register the device.

In the first occurence it was used to try to be nice while releasing the mmap_sem and retrying the fault to work around a locking inversion. The second occurence was never used. There has been some discussion whether we should change the locking order to mmap_sem -> bo_reserve. This patch doesn't address that issue, and leaves that locking order undefined. The solution that we release the mmap_sem if tryreserve fails and wait for the buffer to become unreserved is something we want in any case, and follows how the core vm system waits for pages to be come unlocked while releasing the mmap_sem. The code also outlines what needs to be changed if we want to establish the locking order as mmap_sem -> bo::reserve. One slight issue that remains with this code is that the fault handler might be prone to starvation if another thread countinously reserves the buffer. IMO that usage pattern is highly unlikely.

That's stupid. However, some drivers might have relied on this to clear io memory from old stuff. So instead of a NOP, which would be the most efficient, just clear the destination.
