ASoC: Name iov_iter argument as iterator instead of buffer

2023-09-01T13:38:49+00:00

While transitioning ASoC code for iov_iter usages, I kept the argument
name as "buf" as the original code.  But, iov_iter is an iterator, and
using the name "buf" may be misleading: the crucial difference is that
iov_iter can be proceeded after the operation, hence it can't be
passed twice, while a simple "buffer" sounds as if reusable.

To make the usage clearer, rename the argument from "buf" to "iter".
There is no functional changes, just names.

ASoC: dmaengine: Drop unused iov_iter for process callback

2023-09-01T13:38:29+00:00

Passing the iov_iter to the process callback is rather buggy, as the
iterator has been already processed for playback.  Similarly, it makes
the copy for capture buggy after the process callback reading the
iterator out.  Moreover, all existing process callbacks don't refer to
the passed iterator at all.  So, it's better to drop the argument from
the process callback.

   functions.
 - Lots of work on the SOF framework, AMD and Intel drivers, including a
   lot of cleanup and new device support.
 - Standardisation of the presentation of jacks from drivers.
 - Provision of some generic sound card DT properties.
 - Conversion oof more drivers to the maple tree register cache.
 - New drivers for AMD Van Gogh, AWInic AW88261, Cirrus Logic cs42l43,
   various Intel platforms, Mediatek MT7986, RealTek RT1017 and StarFive
   JH7110.

ALSA: ump: Don't create unused substreams for static blocks

2023-08-24T08:03:17+00:00

When the UMP Endpoint is declared as "static", that is, no dynamic
reassignment of UMP Groups, it makes little sense to expose always all
16 groups with 16 substreams.  Many of those substreams are disabled
groups, hence they are useless, but applications don't know it and try
to open / access all those substreams unnecessarily.

This patch limits the number of UMP legacy rawmidi substreams only to
the active groups.  The behavior is changed only for the static
endpoint (i.e. devices without UMP v1.1 feature implemented or with
the static block flag is set).

Add I2S support for the StarFive JH7110 SoC

2023-08-23T18:54:51+00:00

Merge series from Xingyu Wu :

This patch series adds I2S support for the StarFive JH7110 RISC-V
SoC based on Designware I2S controller. There has three I2S channels
(RX/TX0/TX1) on the JH7110 SoC, one of which is for record(RX) and
two for playback(TX).

The first patch adds support for the StarFive JH7110 SoC in the
Designware I2S bindings.
The second patch adds the ops to get data from platform bus in the
I2S driver.
The third patch adds support for the StarFive JH7110 SoC in
the Designware I2S driver.
The fourth patch fixes the name of I2STX1 pinmux.
The last patch adds device node of I2S RX/TX0/TX1 in JH7110 dts.

This patch series is based on Linux-next(20230818) which is merge
clock, syscon and dma nodes for the StarFive JH7110 SoC.

The series has been tested and works normally on the VisionFive 2
board by plugging an audio expansion board.

ASoC: dwc: i2s: Add StarFive JH7110 SoC support

2023-08-23T12:56:40+00:00

Add StarFive JH7110(TX0/TX1/RX channels) SoC support in the
designware I2S driver and a flag to check if it is on the JH7110 SoC.

These channels need to enable clocks, resets and syscon register on the
JH7110 SoC. So add init ops in platform data for the JH7110 SoC to do this.

Their resets should be deassert before changing the parent of clocks so
these are done in the init ops of platform data.

The I2S controllers use DMA controller by platform data on the JH7110
and their settings about snd_dmaengine_dai_dma_data() should be added
in the dw_configure_dai_by_pd(). And use dmaengine PCM registration if
these do not have IRQ on the JH7110 SoC.

This series is mostly just a resend keeping pace with the kernel under
it, except for a minor fixup in the ASoC stuff.

Thanks,
Charles

ASoC: cs42l43: Add support for the cs42l43

2023-08-18T22:41:54+00:00

The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface
(Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed
for portable applications. It provides a high dynamic range, stereo
DAC for headphone output, two integrated Class D amplifiers for
loudspeakers, and two ADCs for wired headset microphone input or
stereo line input. PDM inputs are provided for digital microphones.

The ASoC component provides the majority of the functionality of the
device, all the audio functions.
