This patch adds mic support to the lpass driver, most of the driver is
reused as it is, only the register level access is changed depending on
te direction of the stream.
ASoC: qcom: add generic bit masks for RDMA and WRDMA
This patch adds generic masks for accessing bits in rdma/wrdma
registers. Doing this would simplify the driver and adding capture
support would be much simpler. Also there is no point in having same
bit masks for bits in both rdma and wrdma registers.
This patch also deletes the RDMA specific bit masks and makes the code
use the generic bit masks.
ASoC: qcom: rename rdma_ch_bit_map to dma_ch_bit_map
rdma_ch_bit_map can be reused for wrdma channel allocations as wrdma
channel numbering start after rdma channel numbers.
With capture support referring rdma_ch_bit_map for wrdma channel allocation
is confusing, so renaming rdma_ch_bit_map to dma_ch_bit_map makes sense.
This patch updates the internal dma allocation callbacks to take the
stream direction so that it can allocate channels suitable for that
stream direction. Before the capture support this was not necessary.
ASoC: qcom: rename rdmactl_audif_start to dmactrl_audif_start
This patch renames rdmactl_audif_start to dmactrl_audif_start as this
is common for both rdma and wrdma. Without this patch the name would be
bit misleading to the readers.
There is no point in having local allocation functions when the driver
can use snd_dma_alloc/free() apis. This patch replaces the local versions
of the dma allocation apis with the snd_dma_alloc/free() apis.
This patch adds msm8x16-wcd codec support which has been tested for
Audio In using Headset Mic/Secondary Mic/Primary Mic and Audio out via
Speaker/Headset.

Patch "wcn36xx: Pad TIM PVM if needed" has caused a regression in mesh

calculated. Thus, msg_body.beacon_length is incorrectly calculated for

wcn36xx: handle rx skb allocation failure to avoid system crash
Lawrence reported that git clone could make system crash on a
Qualcomm ARM soc based device (DragonBoard, 1G memory without
swap) running 64bit Debian.
It's turned out the crash is related with rx skb allocation
failure. git could consume more than 600MB anonymous memory.
And system is in extremely memory shortage case.
But driver didn't handle the rx allocation failure case. This patch
doesn't submit skb to upper layer if rx skb allocation fails.
Instead, it reuse the old skb for rx DMA again. It's more like
drop the packets if system is in memory shortage case.
With this change, git clone is OOMed instead of system crash.

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 1dccb598df549d892b6450c261da54cdd7af44b4 ("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:

copies of similar structures in ASoC headers. This is on purpose to
avoid direct dependencies to ASoC structures in video side driver.

This driver registers for extcon events as part of its probe, but
never unregisters them in case of error in the probe path.
There were multiple issues noticed due to this missing error handling.
One of them is random crashes if the regulators are not ready yet by the
time probe is invoked.
Ivan's previous attempt [1] to fix this issue, did not really address
all the failure cases like regualtor failures.
Currently the rates of the xo and sleep clocks are hard-coded in the
GCC driver, but this is a board layout description that actually should
be in the DT. Moving them into DT also allows us to insert the RPM
controlled clocks between the DT and GCC clocks.
move the allocation of iommu-sec page table into msm_iommu_dev
in order to use properly initialised struct device.
The dma_alloc_attrs would fail to allocate memory with the fake
struct device which was the case before this change.
