cd470fae88 ASoC: Intel: Skylake: Fix test of a field address
Skylake driver uses snd_dma_buffer for data and buffer, these are variables
and not pointer so do not test field addresses.

e797af53b8 ASoC: Intel: Skylake: Fix CLDMA buffer wrap case
When downloading the firmware/module, if the ring buffer boundary
is reached, we need to wrap to the zeroth position. On next copy
we need to copy till end of buffer and the remaining buffer needs
to be copied from zeroth position.

In this case copy was not handled correctly when wrap condition
is reached which caused invalid data to be copied resulting in
invalid hash failure.

This patch fixes the issue by handling copy at the boundary
condition correctly.

Sometimes firmware D3 IPC fails causing firmware to be in invalid

a71e269728 ASoC: Intel: Skylake: Don't enable WAKEENABLE on suspend
For HDA codecs WAKEENABLE bit is to programmed if codec event
change has to wake the system when suspended.

In skylake I2S systems which are currently supported we have
only HDMI codec, which doesn't use this capability to detect a
HDMI connect/ disconnect event. HDMI HDA codec uses display
interface to detect connect/disconnect event.

This patch removes the WAKEBIT enabling during device D0/D3 as
this seems to cause spurious wakes on the system

aaec7e9f78 ASoC: Intel: Skylake: fix typo in sizeof
The size of the pointer to a data structure to send is erroneously
passed to sst_ipc_tx_message_wait() as its tx_bytes argument. It should
be given the size of the pointed skl_ipc_dxstate_info structure instead.

Coincidentally, both the pointer and the structure have the same size of
8 bytes on a 64 bit machine, which "masks" the issue. Compiling for 32
bit reveals the issue more clearly.

Fix the typo for correctness, and to make the code robust to future
evolutions of the skl_ipc_dxstate_info structure size.

This fixes the following coccicheck error:

  sound/soc/intel/skylake/skl-sst-ipc.c:641:8-14: ERROR: application of sizeof to pointer

8724ff1752 ASoC: Intel: Skylake: Add support for virtual dsp widgets

which are not a DSP FW widget and virtual with respect to
firmware. In these case when module has to bind, then the
virtual DSP modules needs to skipped till a actual DSP module is
found which connects the pipelines.

So we need to walk the graph and find a widget which is real in
nature. This patch adds that support and splits
skl_tplg_pga_dapm_pre_pmu_event() fn with parsing code to
skl_tplg_bind_sinks() fn and call that recursively as well as
while parsing

Removing the blob from private data will not allocate memory for module
specific config in which case memcpy will fail. Fix is to assign the ptr
queried from the NHLT table for the endpoint configuration.

9270b7b926 ASoC: Intel: Skylake: Fix return for pm_runtime_get_sync()
pm_runtime_get_sync() will return a negative value in case of
error and can return postive value for success.  The return check
for pm_runtime_get_sync() must be less than 0, so fix it

01bb84b500 ASoC: Intel: Skylake: power down all link in suspend
This ensures that the link is not requesting any clock and the
PLL can turn off. The link is powered when controller is brought
out of reset.

84c9e2836a ASoC: Intel: Skylake: Correct the runtime handler behaviour
On runtime pm resume, we need to download the firmware, also on
suspend we need to ensure all the interrupts from controller and
DSP are disabled.

Also since we download the firmware on resume, we don't need to do
so on init, so remove that bit

def656fe22 ASoC: Intel: Skylake: Verify the status bit before handling interrupt
Like we have in legacy mode HDA driver, we need to check the
status bit and handle interrupt only when it is not zero or all
bits set.  We typically see the status as all 1's when controller
resumes from suspend, So add the check here as well and don't
handle for these cases.

6ea8ba33e6 ASoC: Intel: Skylake: Check CPA bit in DSP core power down
Skylake driver will set the SPA bit to 0 to turn off the DSP core.
Driver will poll the Current Power Active (CPA) bit to match the
Set Power Active (SPA) bit value. When CPA bit matches the value
of SPA bit, the achieved power state has reached.

In case of DSP power down, register that was polled is SPA
instead of CPA. This patch corrects the register to be polled
in case of DSP power down.
