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.
usb: phy: msm: Fix state machine worker logic for OTG mode.
Issue is that if the board is booted without micro usb cable and usb
device attached, kernel fails to populate the usb host and device.
The reason for this is that the state machine worker logic only checks
for USB_DR_MODE_PERIPHERAL and USB_DR_MODE_HOST modes to run worker
thread. However if the phy is configured in OTG mode it would fail
to run the state machine, resulting in failure to detect for very
first time.
This patch fixes by adding OTG checks in to the logic.
Issue is noticed on Qualcomm Dragon board DB410C.

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

pvm_len (referring to the TIM length field) and pad are both incorrectly
calculated. Thus, msg_body.beacon_length is incorrectly calculated for
mesh mode. Fix this.

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.
