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.

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.

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).

Merge series from Xingyu Wu <xingyu.wu@starfivetech.com>:
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.
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.

iov_iter is a universal interface to copy the data chunk from/to
user-space and kernel in a unified manner. This API can fit for ALSA
PCM copy ops, too; we had to split to copy_user and copy_kernel in the
past, and those can be unified to a single ops with iov_iter.
This patch adds a new PCM copy ops that passes iov_iter for copying
both kernel and user-space in the same way. This patch touches only
the ALSA PCM core part, and the actual users will be replaced in the
following patches.
The expansion of iov_iter is done in the PCM core right before calling
each copy callback. It's a bit suboptimal, but I took this now as
it's the most straightforward replacement. The more conversion to
iov_iter in the caller side is a TODO for future.
As of now, the old copy_user and copy_kernel ops are still kept.
Once after all users are converted, we'll drop the old copy_user and
copy_kernel ops, too.

So far we use the embedded struct device for each PCM substreams in
struct snd_pcm. This may result in UAF when the delayed kobj release

(delayed) device release, while the snd_pcm object may be already
gone.

A caveat is that we store the PCM substream pointer to drvdata since
the device resume and others require the access to it.

This patchset first fixes a number of errors made in the hda-mlink

the hda-dai changes where the HDaudio DMA is now used for SSP, DMIC

used and controlled by the audio firmware. The volume of code is
minimized with the abstraction added in previous kernel cycles.
Due to cross-dependencies between ASoC and SoundWire trees, the full
support for jack detection will be deferred to the next kernel
cycle. There's not much point to ask for a sync of the two trees to
support one patch for each tree - we are at -rc5 already.

To enable the speaker output in external boost mode, 2 registers must
be set, one after another. The longer the time between the writes of
the two registers, the more likely, and more loudly a pop may occur.
To minimize this, an mbox command can be used to allow the firmware
to perform this action, minimizing any delay between write, thus
minimizing any pop or click as a result. The old method will remain
when running without firmware.

Move issuing of a CS35L56_MBOX_CMD_SHUTDOWN command and then waiting for
the DSP to reach CS35L56_HALO_STATE_SHUTDOWN in the register appropriate

The ASoC and HDA drivers have structures that contain some of the same
information - instead of maintaining two locations for this data the
drivers should share a common data structure as this will enable common
utility functions to be created.
The first step is to move the location of these members in the ASoC
driver.

A commonly seen pattern is to run snd_ctl_find_id() for a mixer
control element with a given string. Let's provide a standard helper
for achieving that for simplifying the code.

A few ALSA control API helpers like snd_ctl_rename(), snd_ctl_remove()
and snd_ctl_find_*() suppose the callers taking card->controls_rwsem.
But it's error-prone and fragile. This patch set tries to change
those API functions to take the card->controls>rwsem internally by
themselves, so that the drivers don't need to take care of lockings.
After applying this patch set, only a couple of places still touch
card->controls_rwsem (which are OK-ish as they need for traversing the
control linked list).

ALSA: Make control API taking controls_rwsem consistently
A few ALSA control API helpers like snd_ctl_rename(), snd_ctl_remove()
and snd_ctl_find_*() suppose the callers taking card->controls_rwsem.
But it's error-prone and fragile. This patch set tries to change
those API functions to take the card->controls>rwsem internally by
themselves, so that the drivers don't need to take care of lockings.

For reducing the unnecessary use of controls_rwsem in the drivers,
this patch adds a new variant for snd_ctl_find_*() helpers:
snd_ctl_find_id_locked() and snd_ctl_find_numid_locked() look for a
kctl element inside the card->controls_rwsem -- that is, doing the
very same as what snd_ctl_find_id() and snd_ctl_find_numid() did until
now. snd_ctl_find_id() and snd_ctl_find_numid() remain same,
i.e. still unlocked version, but they will be switched to locked
version once after all callers are replaced.
The patch also replaces the calls of snd_ctl_find_id() and
snd_ctl_find_numid() in a few places; all of those are places where we
know that the functions are called properly with controls_rwsem held.
All others are without rwsem (although they should have been).
After this patch, we'll turn on the locking in snd_ctl_find_id() and
snd_ctl_find_numid() to be more race-free.
