ALSA PCM core has an optimized way to communicate with user-space for
its control and status data via mmap on the supported architectures
like x86. Depending on the situation, however, we'd rather want to
enforce user-space notifying the applptr or hwptr change explicitly
via ioctl. For example, the upcoming non-contig and non-coherent
buffer handling would need an explicit sync, and this needs to catch
the applptr and hwptr changes. Also, ASoC SOF driver will have the
SPIB support that has the similar requirement for the explicit control
of the applptr and hwptr.
This patch adds the new PCM hardware info flag,
SNDRV_PCM_INFO_EXPLICIT_SYNC. When this flag is set, PCM core
disables both the control and the status mmap, which enforces
user-space to update via SYNC_PTR ioctl. In that way, drivers can
catch the applptr and hwptr update and apply the sync operation if
needed.

This adds a second mixer control to Digidesign Mbox
to select between Analog/SPDIF capture.
Users will note that selecting the SPDIF input source
automatically switches the clock mode to sync to SPDIF,
which is a feature of the hardware.
(You can change the clock source back to internal if you want
to capture from spdif but not sync to its clock although this mode
is probably not recommended).
Unfortunately, starting the stream resets both modes
to Internally clocked and Analog input mode.

This is an enhancement for the SG-style page handling in vmalloc
buffer handler to calculate the continuous pages.
When snd_sgbuf_get_chunk_size() is called for a vmalloc buffer,
currently we return only the size that fits into a single page.
However, this API call is rather supposed for obtaining the continuous
pages and most of vmalloc or noncontig buffers do have lots of
continuous pages indeed. So, in this patch, the callback now
calculates the possibly continuous pages up to the given size limit.
Note that the end address in the function is calculated from the last
byte, hence it's one byte shorter. This is because ofs + size can be
above the actual buffer size boundary.
Until now, this feature isn't really used, but it'll become useful in
a later patch that adds the non-contiguous buffer type that shares the
same callback function as vmalloc.

Only disable I2C clock 25 ms after not being used.
The current implementation enables and disables the I2C clock for each
I2C transaction. Each enable/disable call requires two verb transactions.
This means each I2C transaction requires a total of four verb transactions
to enable and disable the clock.
However, if there are multiple consecutive I2C transactions, it is not
necessary to enable and disable the clock each time, instead it is more
efficient to enable the clock for the first transaction, and disable it
after the final transaction, which would improve performance.
This is achieved by using a timeout which disables the clock if no request
to enable the clock has occurred for 25 ms.

CS46xx driver switches the buffer depending on the number of periods,
and in some cases it switches to the own buffer without updating the

exotic architectures that require the own mmap call for the coherent

This patch addresses the potential breakage by replacing the buffer
setup with the proper macro. It also simplifies the source code,

Although the regression of the mmap was fixed in the recent commit
dc0dc8a73e ("ALSA: pcm: Fix mmap breakage without explicit buffer
setup"), RME9652 and HDSP drivers have still potential issues with
their mmap handling. Namely, they use the default mmap handler
without the standard buffer preallocation, and PCM core wouldn't use
the coherent DMA mapping. It's practically OK on x86, but on some
exotic architectures, it wouldn't work.

Currently we check only the substream->dma_buffer as the preset of the
buffer configuration for verifying the availability of mmap. But a
few drivers rather set up the buffer in the own way without the
standard buffer preallocation using substream->dma_buffer, and they
miss the proper checks. (Now it's working more or less fine as most
of them are running only on x86).
Actually, they may set up the runtime dma_buffer (referred via
snd_pcm_get_dma_buf()) at the open callback, though. That is, this
could have been used as the primary source.
This patch changes the hw_support_mmap() function to check the runtime
dma buffer at first. It's usually NULL with the standard buffer
preallocation, and in that case, we continue checking
substream->dma_buffer as fallback.

For those with UNKNOWN buffer type (i.e. the uninitialized / unused

properly and blindly trust the hardware info bit.

This patch adds the mmap workaround for WC pages to SG-buffer

returning an error after setting the pgprot, so it won't work in all
cases but merely for PCM (which is currently the only use case).

must be enabled (corresponding to the low and high phases of LRCLK.)
The selection of the valid data channels is done by setting the DAC
CHA_SEL and CHB_SEL. CHA_SEL is always the first (left) channel,

The lowest valid SCLK corresponds to 44.1 kHz at 16-bit. Sample
rates less than this would produce SCLK below the minimum when using
a normal I2S frame. A constraint must be applied to prevent this.
The constraint is not applied if the machine driver sets SCLK, to
allow setups where the host generates additional bits per LRCLK
phase to increase the SCLK frequency. In these cases the machine
driver would always have to inform this driver of the actual SCLK,
and it must select a legal SCLK.
