This update bring in new APIs in core and usage of those in SKL driver.
The series is broadly of three parts
- first two are fixes on the driver
- then we add DMA resume capability in HDA core and use it to save restore
DMA link values and add DMA resume capability in driver
- lastly, we add support for MISCBDCGE configuration in core and use it
while resetting and also for phrase detection per HW recommendation
This should be merged thru ASoC tree due to obvious dependencies. Takashi
would need your ack on core patches
changes in v2:
- move msicbdge api to driver and as a consequence sqash into into first
use
- fix lkp warning

Skylake sports new capability of DMA resume, DRSM where we can
resume the DMA. This capability is defined by presence of
AZX_DRSM_CAP_ID.
If this capability is present, we use this capability.
So we add:
snd_hdac_ext_stream_drsm_enable() - DMA resume caps
snd_hdac_ext_stream_set_dpibr() - set the DMA position
snd_hdac_ext_stream_set_lpib() - set the lpib

A stream is by default in coupled mode, in DSP operation we move
it to decoupled mode. On cleanup HW expects that we leave it back
to default state so couple the DMA on cleanup.

We have an API for powering down all links, we need a similar one
for powering up links, so add for power up as well

MISCBDCGE is a new register for Misc Backbone clock gate control
which is useful to control while resetting the link and ensuring
controller is in required state so add API to control it
HW recommends that we reset with CGCTL.MISCBDCGE disabled, so add
that while doing init chip and reset sequence.

When device enters active suspend, we should turn off the links
as they are not in use. Similarly we need to bring back links
when we exit active suspend.

In active suspend, any HDA interrupt should wake the system. When device
enters active suspend, we need to enable HDA controller interrupt as wake
source. Similarly disable HDA controller interrupt as wake source when
exiting active suspend.

Use the DMA resume capability to resume the DMA position when
stream is suspended/resumed.
In suspend we save the position and when stream is resumed the stream needs
to be started from the position when the stream was suspended using the new
DMA resume capabilities
