Multiple codecs of the same type on the same card
by Ricard Wanderlof 18 Feb '22

18 Feb '22

When adding codecs to a card, all the controls of each individual codec are visible as controls for the complete card. But how does one handle the case of multiple codecs of the same type, for instance two identical codecs being used in TDM mode to create a multi channel card? Is there some method for resolving the fact that the control names naturally conflict? Or is this expected to be resolved in the machine driver? Currently I've been using simple-card, but perhaps this type of configuration is too advanced to be resolved for that, and a specialized machine driver is needed? /Ricard -- Ricard Wolf Wanderlof ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30

[PATCH] ASoC: codecs: Add power domains support in digital macro codecs
by Srinivasa Rao Mandadapu 17 Feb '22

17 Feb '22

Add support for enabling required power domains in digital macro codecs. macro and dcodec power domains are being requested as clocks by HLOS in ADSP based architectures and ADSP internally handling as powerdomains. In ADSP bypass case need to handle them as power domains explicitly.

[PATCH] ASoC: SOF: Replace zero-length array with flexible-array member
by Stephen Kitt 17 Feb '22

17 Feb '22

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members"[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

[PATCH v2] ASoC: SOF: core: unregister clients and machine drivers in .shutdown
by Kai Vehmanen 17 Feb '22

17 Feb '22

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> On a platform shutdown, the expectation for most drivers is that userspace tasks will release all resources. When those sequences do not complete, it can be the case that PCM devices exposed by ALSA cards are used *after* the DSP shutdown completes, leading to a platform hang. When the clients and machine drivers provide an _unregister callback, let's invoke it in the shutdown sequence.

This one patch is over 300K which is a bit much in one go, especially when it's not just all big tables.

[PATCH 0/2] ASoC: audio_graph_card2: Support variable slot widths
by Richard Fitzgerald 17 Feb '22

17 Feb '22

This adds support for I2S/TDM links where the slot width varies depending on the sample width, in a way that cannot be guessed by component hw_params(). A typical example is: - 16-bit samples use 16-bit slots - 24-bit samples use 32-bit slots There is no way for a component hw_params() to deduce from the information it is passed that 24-bit samples will be in 32-bit slots. Some audio hardware cannot support a fixed slot width or a slot width equal to the sample width in all cases. This is usually due either to limitations of the audio serial port or system clocking restrictions. These two patches add support for defining a mapping between sample widths and sample slots. This allows audio_graph_card2 to be used in these situations instead of having to write a custom machine driver.
