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.

The update of rate_num/den and msbits were factored out to

ASoC: Fixes that got left after v6.4

These were some changes in my v6.4 branch that never got sent as fixes,
none of them super urgent thankfully.

A few newly added functions aren't built unless CONFIG_OF is set,
which result in the build failure due to defined-but-not-used errors.

Put "#ifdef CONFIG_OF" around those functions to suppress the build

ASoC: Updates for v6.6

The rest of the updates for v6.6, some of the highlights include:

 - A big API cleanup from Morimoto-san, rationalising the places we put
   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.

USB-audio driver can still submit URBs while the device is being
disconnected, and it may result in spurious error messages like:
  usb 1-2: cannot submit urb (err = -19)
  usb 1-2: Unable to submit urb #0: -19 at snd_usb_queue_pending_output_urbs
  usb 1-2: cannot submit urb 0, error -19: no device
Although those are harmless, they are just ugly.

This patch tries to avoid spewing such error messages when the device
is already at the disconnected state.  It also skips the superfluous
xfer notification, too.

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).

To make it clearer which legacy substream corresponds to which UMP
group, fill the subname field of each substream object with the group

derived UMP, but it's another feature extension.

The legacy rawmidi devices are the shadows of the main UMP devices,
hence it's better to initialize them after all UMP Endpoints are
parsed.  Then, at the moment the legacy rawmidi is created, we already
know the static flag or the proper EP name string, and we can fill
those information at UMP core side instead of fiddling the attributes
at a later point.

ASoC: Fixes for v6.5

A relatively large but generally not super urgent set of fixes for ASoC,
including some quirks and a MAINTAINERS update.  There's also an update
to cs35l56 to change the firmware ABI, there are no current shipping
systems which use the current interface and the sooner we get the new
interface in the less likely it is that something will start.

It'd be nice if these landed for v6.5 but not the end of the world if
they wait till v6.6.

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

The second patch adds the ops to get data from platform bus in the

The third patch adds support for the StarFive JH7110 SoC in

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.

Renesas Sound has ADG for clock control. Basically it needs
accurately divisible external input clock. But sometimes
sometimes it doesn't have to be accurate for some reason.

We can use ADG clk_i for such case. It came from CPG as
very high rate clock, but is not accurately divisible for
48kHz/44.1kHz rate, but enough for approximate rate.

This patch set support such use case.

We don't need to have "format" property on DT any more if

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.
