I can reliably reproduce this problem by running 'tail' on the registers
file in debugfs for the hdmi regmap.

 # 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.

      Merge series "ASoC: qcom: Fix broken lpass driver" from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:

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.

Thanks,
srini

      Merge series "Add KUNIT tests for ASoC topology" from Amadeusz Sławiński<amadeuszx.slawinski@linux.intel.com>:

This series adds unit tests for ASoC topology.

First fix problems found when developing and running test cases and
then add tests implementation.

Tests themselves are quite simple and just call
snd_soc_tplg_component_load() with various parameters and check the
result. Tests themselves are described in more detail in commits
adding them.

Goal is to expand the amount of test cases in following patches.

Prerequisity for this patchset are 2 patches which have already been
sent:
https://lore.kernel.org/alsa-devel/20210114163602.911205-1-amadeuszx.slawinski@linux.intel.com/T/#t

Description on how typical test case itself works:

In order to load topology we need to have 3 things:
card, codec component & platform component.

In typical test case we register card and platform component and bind
to dummy codec. There are of course execeptions, when we want to
test behaviour of topology API when component or card is missing.
Note that this is bit different from typical scenario (in SOF and skylake
drivers) where card is registered by machine driver and component by
platform driver, as we register both when setting up test.

If you check the test case most of them have similar architecture of:
1.
	/* run test */
	ret = snd_soc_register_card(&kunit_comp->card);
	if (ret != 0 && ret != -EPROBE_DEFER)
		KUNIT_FAIL(test, "Failed to register card");

2.
	ret = snd_soc_component_initialize(&kunit_comp->comp, &test_component, test_dev);
	KUNIT_EXPECT_EQ(test, 0, ret);

3.
	ret = snd_soc_add_component(&kunit_comp->comp, NULL, 0);
	KUNIT_EXPECT_EQ(test, 0, ret);

Ad. 1.
First we register card, which in most tests returns -EPROBE_DEFER
(from snd_soc_bind_card()), as platform component is not yet created.
I test for both 0 and -EPROBE_DEFER, as it makes it easier to reshuffle
this code around if needed and there is one test case which does it in
different order.

Ad. 2.
Then we initialize platform component with structure pointing at proper
probe function, which calls snd_soc_tplg_component_load() with test
parameters and checks expected result.

Ad. 3.
And then in follow up we call snd_soc_add_component() which creates
platform component for us and calls snd_soc_try_rebind_card() which
if everything is bound properly calls previously set probe function.
