ASoC: Remove unused hw_write_t type

2022-06-24T15:21:41+00:00

Commit 81da8a0b7975 ("ASoC: remove codec hw_write/control_data") removed
use of hw_write_t in struct snd_soc_codec, but it left type definition.
Fully clean it up.

ASoC: soc.h: Add SOC_SINGLE_S_EXT_TLV macro

2022-04-25T12:58:22+00:00

Add a SOC_SINGLE_S_EXT_TLV macro as a convenience wrapper
around SOC_DOUBLE_R_S_EXT_TLV for mono volume controls.

ASoC: soc.h: Introduce SOC_DOUBLE_R_S_EXT_TLV() macro

2022-04-25T12:58:21+00:00

A straightforward extension of the SOC_DOUBLE_R_S_TLV() macro that
allows the get and put functions to be customised.

ASoC: soc-utils: Add helper to calculate BCLK from TDM info

2022-04-05T17:27:55+00:00

Add a helper function snd_soc_tdm_params_to_bclk() to calculate
the bclk from params info and the tdm sots configuration.

When using a TDM frame of N slots of width W bits:

   bclk = sample_rate * N * W

As a convenience to simplify calling code, if the slot count or
slot width are 0 a value will be obtained from the params. This
allows calling code to use this one function to handle cases of
TDM where only one parameter is fixed, or I2S where the slot width
is fixed (for example to set a 32-bit slot for 24-bit samples).

Also as a convenience the slot count can optionally be rounded up
to a multiple. This is mainly useful for I2S systems, since I2S has
two phases of LRCLK the number of slots is always a multiple of 2.

ASoC: soc.h: Add SOC_SINGLE_S_TLV() macro

2022-04-05T17:27:54+00:00

Add a convenience macro for defining a single (mono) TLV control
with a signed value. This can already be done by using
SOC_DOUBLE_R_S_TLV() with the same address for left and right
registers, but a dedicated macro is more readable.

ASoC: core: Add snd_soc_of_parse_pin_switches() from simple-card-utils

2021-12-23T18:34:23+00:00

The ASoC core already has several helpers to parse card properties
from the device tree. Move the parsing code for "pin-switches" from
simple-card-utils to a shared snd_soc_of_parse_pin_switches() function
so other drivers can also use it to set up pin switches configured in
the device tree.

ASoC: soc-pcm: Fix and cleanup DPCM locking

2021-12-14T17:15:45+00:00

The existing locking for DPCM has several issues
a) a confusing mix of card->mutex and card->pcm_mutex.
b) a dpcm_lock spinlock added inconsistently and on paths that could
be recursively taken. The use of irqsave/irqrestore was also overkill.

The suggested model is:

1) The pcm_mutex is the top-most protection of BE links in the FE. The
pcm_mutex is applied always on either the top PCM callbacks or the
external call from DAPM, not taken in the internal functions.

2) the FE stream lock is taken in higher levels before invoking
dpcm_be_dai_trigger()

3) when adding and deleting a BE, both the pcm_mutex and FE stream
lock are taken.

ASoC: soc-pcm: add a flag to reverse the stop sequence

2021-07-16T12:54:58+00:00

On stream stop, currently CPU DAI stop sequence invoked first
followed by DMA. For Few platforms, it is required to stop the
DMA first before stopping CPU DAI.

Introduced new flag in dai_link structure for reordering stop sequence.
Based on flag check, ASoC core will re-order the stop sequence.
