The test here is intended intended to prevent shift wrapping bugs when we do "1U << idx2". We should consider the number of bits in a u32 instead of the number of bytes. [fix another chunk similarly by tiwai] Fixes: 7bb2491b ('ALSA: Add kconfig to specify the max card numbers') Signed-off-by:

ASUS Zenbook UX31A has yet another problem -- softer output level than others. According to the measurement, the peak output difference between 31A and 31E is 5dB. As ALC269VB has a COEF for the class-D pre-amp, let's apply it for +5dB. Signed-off-by:

The prefix for the codec driver can be used during dual identical codec usecases. However, dapm adds prefix twice for codec DAI widget in snd_soc_dapm_add_route API. This change is to avoid double prefix addition for codec DAI widget and is needed while using identical dual codecs. Signed-off-by:

Currently compressed audio streams are statically routed from the /dev to the DAI link. Some DSPs can route compressed data to multiple BE DAIs like they do for PCM data. Add support to allow dynamically routed compressed streams using the existing DPCM infrastructure. This patch adds special FE versions of the compressed ops that work out the runtime routing.

When we plug a 3-ring headset on some Dell machines, the headset mic can't be detected, after apply this patch, the headset mic can work well on all those machines. On the machine with the Subsytem ID 0x10280610, if we use ALC269_FIXUP_DELL1_MIC_NO_PRESENCE, the headset mic can be detected and work well, but the sound can't be outputed via headphone anymore, use ALC269_FIXUP_DELL3_MIC_NO_PRESENCE can fix this problem.

range_min is the lowest address in the virtual register range. This is the first register with address 0, not the first register of page 1.

The Samsung dmaengine ASoC driver is used with two different dmaengine drivers. The pl80x, which properly supports residue reporting and the pl330, which reports that it does not support residue reporting. So there is no need to manually set the NO_RESIDUE flag. This has the advantage that a proper (race condition free) PCM pointer() implementation is used when the pl80x driver is used. Also once the pl330 driver supports residue reporting the ASoC PCM driver will automatically start using it. Signed-off-by:

The pl330 driver properly reports that it does not have residue reporting support, which means the PCM dmanegine driver is able to figure this out on its own. So there is no need to set the flag manually. Removing the flag has the advantage that once the pl330 driver gains support for residue reporting it will automatically be used by the generic dmaengine PCM driver. Signed-off-by:

The dmaengine framework now exposes the granularity with which it is able to report the transfer residue for a certain DMA channel. Check the granularity in the generic dmaengine PCM driver and a) Set the SNDRV_PCM_INFO_BATCH if the granularity is per period or worse. b) Fallback to the (race condition prone) period counting if the driver does not support any residue reporting.

Currently we have two different snd_soc_platform_driver structs in the generic dmaengine PCM driver. One for dmaengine drivers that support residue reporting and one for those which do not. When registering the PCM component we check whether the NO_RESIDUE flag is set or not and use the corresponding snd_soc_platform_driver. This patch modifies the driver to only have one snd_soc_platform_driver struct where the pointer() callback checks the NO_RESIDUE flag at runtime. This allows us to set the NO_RESIDUE flag after the PCM component has been registered. This becomes necessary when querying whether the dmaengine driver supports residue reporting from the dmaengine driver itself since the DMA channel might only be requested after the PCM component has been registered.

This patch adds a new field to the dma_slave_caps struct which indicates the granularity with which the driver is able to update the residue field of the dma_tx_state struct. Making this information available to dmaengine users allows them to make better decisions on how to operate. E.g. for audio certain features like wakeup less operation or timer based scheduling only make sense and work correctly if the reported residue is fine-grained enough. Right now four different levels of granularity are supported: * DESCRIPTOR: The DMA channel is only able to tell whether a descriptor has been completed or not, which means residue reporting is not supported by this channel. The residue field of the dma_tx_state field will always be 0. * SEGMENT: The DMA channel updates the residue field after each successfully completed segment of the transfer (For cyclic transfers this is after each period). This is typically implemented by having the hardware generate an interrupt after each transferred segment and then the drivers updates the outstanding residue by the size of the segment. Another possibility is if the hardware supports SG and the segment descriptor has a field which gets set after the segment has been completed. The driver then counts the number of segments without the flag set to compute the residue. * BURST: The DMA channel updates the residue field after each transferred burst. This is typically only supported if the hardware has a progress register of some sort (E.g. a register with the current read/write address or a register with the amount of bursts/beats/bytes that have been transferred or still need to be transferred).

A bit of special care is necessary when creating the intersection of two rate masks. This comes from the special meaning of the SNDRV_PCM_RATE_CONTINUOUS and SNDRV_PCM_RATE_KNOT bits, which needs special handling when intersecting two rate masks. SNDRV_PCM_RATE_CONTINUOUS means the hardware supports all rates in a specific interval. SNDRV_PCM_RATE_KNOT means the hardware supports a set of discrete rates specified by a list constraint. For all other cases the supported rates are specified directly in the rate mask. Signed-off-by:

If none of the components (CODEC or CPU DAI) sets a maximum sample rate we'll end up with the rate_max field of the runtime hardware set to 0. (Note that it is still possible for the components to constrain the supported sample rates using other methods, e.g. setting a list constraint) If rate_max is 0 this means that the sound card doesn't support any rates at all, which is not the desired result. So initialize rate_max to UINT_MAX. For symmetry reasons also set rate_min to 0. Signed-off-by:
