97c52eb969 ASoC: qcom: move clock names into LPASS variant struct
The clock names for the two supported codecs are either
"mi2s-*" name variants generated by code. This naming scheme
does not work for platforms like MSM8660 which has I2S channels
named CODEC_I2S_SPKR (rather than just "MI2S tertiary" and other
repetitive names) and consequently have clocks named
"codec-i2s-spkr-osr-clk" and similar.

Skip the runtime generation of clock names and replace it with
name lookup tables encoded into the variant data.

183b8021fc scripts/spelling.txt: add "intialization" pattern and fix typo instances
Fix typos and add the following to the scripts/spelling.txt:

  intialization||initialization

The "inintialization" in drivers/acpi/spcr.c is a different pattern but
I fixed it as well in this commit.

b6e643adfd ASoC: qcom: Drop __func__ usage from log prints

46dccc3573 ASoC: qcom: lpass-cpu: Remove unnecessary clock checks
Clean up the clock calling code by removing numerous IS_ERR() checks by

ee2bd216e1 ASoC: lpass-platform: fix uninitialized variable
In commit 022d00ee0b ("ASoC: lpass-platform: Fix broken pcm data
usage") the stream specific information initialization was broken, with
the dma channel information not being initialized if there was no
alloc_dma_channel() helper function.

Before that, the DMA channel number was implicitly initialized to zero
because the backing store was allocated with devm_kzalloc().  When the
init code was rewritten, that implicit initialization was lost, and gcc
rightfully complains about an uninitialized variable being used.

3b89e4b77e ASoC: lpass-platform: initialize dma channel number
A bugfix accidentally removed the implicit initialization of the
dma channel number, causing undefined behavior when
v->alloc_dma_channel is NULL:

sound/soc/qcom/lpass-platform.c: In function ‘lpass_platform_pcmops_open’:
sound/soc/qcom/lpass-platform.c:83:29: error: ‘dma_ch’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

This adds back an explicit initialization to zero, restoring the
previous behavior for that case.

022d00ee0b ASoC: lpass-platform: Fix broken pcm data usage
This patch fixes lpass-platform driver which was broken in v4.9-rc1.
lpass_pcm_data data structure holds information specific to stream.
Holding a single private pointer to it in global lpass_data
will not work, because it would be overwritten by for each pcm instance.

This code was breaking playback when we have both playback and capture
pcm streams, as playback settings are over written by capture settings.

Fix this by moving channel allocation logic out of pcm_new to pcm_open
so that we can store the stream specific information in private_data of
snd_pcm_runtime.

The commit that caused us to specify LE device endianness here,
29bb45f25f (regmap-mmio: Use native endianness for read/write,
2015-10-29), has been reverted in mainline so now when we specify
LE it actively breaks big endian kernels because the byte
swapping in regmap-mmio is incorrect. Let's revert this change
because it will 1) fix the big endian kernels and 2) be redundant
to specify LE because that will become the default soon.

f5f76ea75d ASoC: qcom: use correct device pointer in dma allocation
dev pointer in struct snd_soc_pcm_runtime does not have dma_ops set. In
v4.4 kernel dma_ops would end up pointing to dummy_dma_ops in such cases.
So attempting to use such device in allocating coherent memory on aarch64
would fail.

According to commit 1dccb598df ("arm64:
simplify dma_get_ops") The current behavior of dma_get_ops is to fall
back to the global dma_ops when a device has not set its own dma_ops,
but only for DT based systems.

So, this patch fixes the driver to use correct device pointer while
allocating coherent memory, and also deletes un-necessary dma_mask setup
on soc_runtime->dev.

Without this patch lpass driver would fail with below log:
...

18560a4e3b ASoC: qcom: Specify LE device endianness
This is a little endian device, but so far we've been relying on
the regmap mmio bus handling this for us without explicitly
stating that fact. After commit 4a98da2164cf (regmap-mmio: Use
native endianness for read/write, 2015-10-29), the regmap mmio
bus will read/write with the __raw_*() IO accessors, instead of
using the readl/writel() APIs that do proper byte swapping for
little endian devices.

So if we're running on a big endian processor and haven't
specified the endianness explicitly in the regmap config or in
DT, we're going to switch from doing little endian byte swapping
to big endian accesses without byte swapping, leading to some
confusing results. Specify the endianness explicitly so that the
regmap core properly byte swaps the accesses for us.
