This patchset tries to resolve the diversity in the audio LED
control among the ALSA drivers. A new control layer registration
is introduced which allows to run additional operations on
top of the elementary ALSA sound controls.
A new control access group (three bits in the access flags)
was introduced to carry the LED group information for
the sound controls. The low-level sound drivers can just
mark those controls using this access group. This information
is not exported to the user space, but user space can
manage the LED sound control associations through sysfs
(last patch) per Mark's request. It makes things fully
configurable in the kernel and user space (UCM).
The actual state ('route') evaluation is really easy
(the minimal value check for all channels / controls / cards).
If there's more complicated logic for a given hardware,
the card driver may eventually export a new read-only
sound control for the LED group and do the logic itself.
The new LED trigger control code is completely separated
and possibly optional (there's no symbol dependency).
The full code separation allows eventually to move this
LED trigger control to the user space in future.
Actually it replaces the already present functionality
in the kernel space (HDA drivers) and allows a quick adoption
for the recent hardware (ASoC codecs including SoundWire).
snd_ctl_led 24576 0
The sound driver implementation is really easy:
1) call snd_ctl_led_request() when control LED layer should be
automatically activated
/ it calls module_request("snd-ctl-led") on demand /
2) mark all related kcontrols with
SNDRV_CTL_ELEM_ACCESS_SPK_LED or
SNDRV_CTL_ELEM_ACCESS_MIC_LED

Had a typo in lpass platform driver that resulted in crash
during suspend/resume with an HDMI dongle connected.
The regmap read/write/volatile regesters validation callbacks in lpass-cpu
were using MI2S rdma_channels count instead of hdmi_rdma_channels.
This typo error causing to read registers from the regmap beyond the length

This fix avoids the need for reducing number hdmi_rdma_channels,
which is done in

The "dai_id" given into LPAIF_INTFDMA_REG(...) is already the real

For IPQ806x (and SC7180 since commit 09a4f6f5d2

now often an out-of-bounds read because the indexes in the "dai_driver"

I can reliably reproduce this problem by running 'tail' on the registers

# tail /sys/kernel/debug/regmap/62d87000.lpass-lpass_hdmi/registers
[ 84.658733] Unable to handle kernel paging request at virtual address ffffffd0128e800c
This crash happens because we're trying to read registers from the
regmap beyond the length of the mapping created by ioremap().
The number of hdmi_rdma_channels determines the size of the regmap via
this code in sound/soc/qcom/lpass-cpu.c:
lpass_hdmi_regmap_config.max_register = LPAIF_HDMI_RDMAPER_REG(variant, variant->hdmi_rdma_channels);
According to debugfs the size of the regmap is 0x68010 but according to
the DTS file posted in [1] the size is only 0x68000 (see the first reg
property of the lpass_cpu node). Let's change the number of channels to
be 3 instead of 4 so the math works out to have a max register of
0x67010, nicely fitting inside of the region size of 0x68000.
Note: I tried to bump up the size of the register region to the next
page to include the 0x68010 register but then the tail command caused
SErrors with an async abort, implying that the register region doesn't
exist or it isn't clocked because the bus is telling us that the
register read failed. I reduce the number of channels and played audio
through the HDMI channel and it kept working so I think this is correct.

LPASS driver is partially broken on DragonBoard DB410c on 5.10 and
its totally broken on other Supported Qualcomm SoCs.
This was due to DAI ids being over written by the SoC specific header files
in the dt-bindings.
Idea of having SoC specific headers is not doable when we are dealing with
a common driver. So this patchset attempts to fix this properly by creating
a common dt-bindings header for lpass which can be updated with new entries
if required. This patchset also add an simple of_xlate function to resolve
the dai names and different SoCs might not have 1:1 mapping for the
dai_driver array with dai ids.
Changes since v1:
- removed array indexes as suggested by Stephan G.
- rebased to sound/for-next branch
- collected Srinivasa tested-by tag for sc7180 platform.

lpass hdmi support patch totally removed support for MI2S TERTIARY
and QUATERNARY.
One of the major issue was spotted with the design of having
separate SoC specific header files for the common lpass driver.
This design is prone to break as an when new SoC header is added
as the common DAI ids of other SoCs will be overwritten by the
new ones.
Having a common header qcom,lpass.h should fix the issue and any new
DAI ids should be added to the common header.
With this change lpass also needs a new of_xlate function to resolve
dai name.

Here's some minor code cleanups for the lpass-cpu driver. I noticed that
it casts away const from the driver data from DT. That's not great but
fixing it is a little more involved. I'll get to it later. There's also
some questionable clk_get() usage that should probably be
clk_get_optional(). For now this should help a little.

We don't need to print an error message when these ioremap operations
fail. The function that returns an error already prints an error message
and properly attributes it to the device. Drop them to save some code.

We don't need to cast away __iomem when testing with IS_ERR() or
converting with PTR_ERR(). Modern sparse can handle this just fine.
Drop it.

This device can sometimes have multiple regmaps. Let's add a name so
that we can differentiate in debugfs more easily.

This looks like a left over debug print that tells us that HDMI is
enabled. Let's remove it as that's definitely not an error to have HDMI
enabled.

At the moment it is necessary to set up the DAPM routes between
front-end AIF<->DAI explicitly in the device tree, e.g. using
audio-routing =
"MM_DL1", "MultiMedia1 Playback",
"MM_DL3", "MultiMedia3 Playback",
"MM_DL4", "MultiMedia4 Playback",
"MultiMedia2 Capture", "MM_UL2";
This is prone to mistakes and (sadly) there is no clear error if one
of these routes is missing. :(
Actually, this should not be necessary because the ASoC core normally
automatically links AIF<->DAI within snd_soc_dapm_link_dai_widgets().
This is done using the "stname" parameter of SND_SOC_DAPM_AIF_IN/OUT.
For SND_SOC_DAPM_AIF_IN("MM_DL1", "MultiMedia1 Playback", 0, 0, 0, 0),
it should create the route from above: MM_DL1 <-> MultiMedia1 Playback.
This does not work at the moment because the AIF widget (MM_DL1)
and the DAI widget (MultiMedia1 Playback) belong to different
DAPM contexts (q6routing / q6asm-dai).
Fix this by declaring the AIF widgets in the same driver as the DAIs
(q6asm-dai). Now the routes above are created automatically
and no longer need to be specified in the device tree.
This is also more consistent with the back-end AIFs which are already
declared in q6afe-dais instead of q6routing. q6routing should only link
the components together using mixers.

MI2S and DMA control registers are not volatile, so remove these from volatile registers list.
Registers reset state check by reading non volatile registers makes no use,
so remove error check from cpu and platform trigger callbacks.
Initialized map variable two times in lpass platform trigger API,
so remove redundant initialization.

setting clock rate on child clocks without a parent clock rate will
result in zero clk rate for child. This also means that when audio
is started dsp will attempt to access registers without enabling
clock resulting in board boot up.
Fix this by adding the missing parent clock rate.

Fix enabling BCLK and LRCLK only when LPAIF is invalid state and
bit clock in enable state.
In device suspend/resume scenario LPAIF is going to reset state.
which is causing LRCLK disable and BCLK enable.
Avoid such inconsitency by removing unnecessary cpu dai prepare API,
which is doing LRCLK enable, and by maintaining BLCK state information.
