Subject: [PATCH 00/10] ASoC: qcom: q6dsp: few fixes and enhancements

This patchset contains few fixes for the bugs hit during testing with
Monza EVK platform
- around array out of bounds access on dai ids which keep extending but
  the drivers seems to have hardcoded some numbers, fix this and clean
the mess up.
- flooding rpmsg with write requests due to not resetting queue pointer,
  fix this resetting the pointer in trigger stop.
- possible multiple graph opens which can result in open failures.

Apart from this few new enhancements to the dsp side
- add new LPI MI2S and senary dai entires
- handle pipewire and Displayport issues by moving graph start to
  trigger level, which should fix outstanding pipewire and DP issues on
Qualcomm SoCs.
- remove some unnessary loops in hot path
- support early memory map on DSP.


Thanks,
Srini
