This driver is assuming that all adg->clk[i] is not NULL.
Because of this prerequisites, for_each_rsnd_clk() is possible to work
for all clk without checking NULL. In other words, all adg->clk[i]
should not NULL.
Some SoC might doesn't have clk_a/b/c/i. devm_clk_get() returns error in
such case. This driver calls rsnd_adg_null_clk_get() and use null_clk
instead of NULL in such cases.
But devm_clk_get() might returns NULL even though such clocks exist, but
it doesn't mean error (user deliberately chose to disable the feature).
NULL clk itself is not error from clk point of view, but is error from
this driver point of view because it is not assuming such case.
But current code is using IS_ERR() which doesn't care NULL.
This driver uses IS_ERR_OR_NULL() instead of IS_ERR() for clk check.
And it uses ERR_CAST() to clarify null_clk error.
One concern here is that it unconditionally uses null_clk if clk_a/b/c/i
was error. It is correct if it doesn't exist, but is not correct if it
returns error even though it exist.
It needs to check "clock-names" from DT before calling devm_clk_get() to
handling such case. But let's assume it is overkill so far.

dma_request_chan() returns error pointer in case of failures, but
the rz_ssi_dma_request() checked for NULL pointer instead.
This patch fixes the issue by checking for ERR_PTR() instead of

Use "cfg-lineout:2" in the components string on boards with a lineout
instead of "cfg-lineout:1", this better mirrors the speaker part of
the components string where we use "cfg-spk:1" for devices with a single
speaker and "cfg-spk:2" for stereo speakers.
The lineout is stereo by default, so using ":2" makes more sense, this
way we keep ":1" reserved in case we ever encounter a device with
a mono lineout.
We can make this change without breaking userspace because no kernel
has shipped with "cfg-lineout:1" in the component-string yet; and there
also are no userspace bits (UCM profiles) checking for this yet.

2.17.1
This patchset provides an optimization that result in significant power
savings on Intel HDAudio platforms using SOF (Sound Open Firmware).
We previously prevented the Intel DSP from enabling the DMI_L1
capability to work-around issues with pause on capture streams. It
turns out that this also prevented the platform from entering high C
states in full-duplex usages such as videoconferencing - a rather
basic use case since the start of the pandemic.
The support for pause_push/release was already a bit controversial for
Intel platforms, in theory platforms should only enable PAUSE if they
can resume on the same sample, which is not the case on any Intel
platform.
With this patchset, when the user enables DMI L1 via a kernel
parameter, the PAUSE support is disabled for capture streams. A kernel
parameter is far from ideal but it's a placeholder until we have an
API to negotiate capabilities between applications and driver, and
it's far less confusing than a Kconfig option.
Changes since v1:
Removal of SPIB support since it may conflict with Takashi's memalloc
changes. These SPIB changes will be provided after rebase.
Addition of one cleanup for cppcheck warning
Move all changes to intel/ directory, no changes in shared code
Flipped the logic: the selection of DMI L1 disables PAUSE
Pierre-Louis Bossart (4):
ASoC: SOF: Intel: Kconfig: clarify DMI L1 option description
ASoC: SOF: Intel: hda-stream: remove always true condition
ASoC: SOF: Intel: simplify logic for DMI_L1 handling
ASoC: SOF: Intel: make DMI L1 selection more robust

In current ACPI-based devices, the DSDT does not include any of the
properties required by the codec driver. This is not an ACPI
limitation proper since the _DSD method could be used, as done for
Camera and SoundWire in newer platforms. For legacy devices, there is
unfortunately no other option than using a work-around: we add
properties to the codec device from the machine driver.
To avoid any issues with the codec driver being unbound, we need to
keep a reference to the codec device until the card is removed.

Exposing the DMI L1 configuration as a kernel Kconfig option was in
hindsight a really bad idea. It led to several errors reported by
distributions which selected it by mistake.
The Kconfig is now replaced with a kernel parameter. Since DMI L1
entry is incompatible with pause on a capture stream, the latter is
disabled when the kernel parameter is set.
Experimental results show an increased residency in higher C states
and a significant decrease of system power consumption for "work from
home" usages such as VoIP calls.

When I booted up on a board that had a slightly different codec
stuffed on it, I got this message at bootup:
rt5682 9-001a: Device with ID register 6749 is not rt5682
That's normal/expected, but what wasn't normal was the splat that I
got after:
WARNING: CPU: 7 PID: 176 at drivers/regulator/core.c:2151 _regulator_put+0x150/0x158
pc : _regulator_put+0x150/0x158

This is because the error paths don't turn off the regulator. Let's
fix that.

cppcheck reports below warning.
q6adm.c:475]: (style) Variable 'matrix_map' is reassigned a value before the
old one has been used.
This is due to unnecessary initialization of variable matrix_map, which is
now removed as part of this patch.
