Subject: [PATCH v2 resend 0/3] ASoC: SOF: fix suspend ordering with runtime idle
Date: Tue, 2 Jul 2019 16:24:25 +0300 [thread overview]
Message-ID: <20190702132428.13129-1-kai.vehmanen@linux.intel.com> (raw)
Hi all,
this series addresses issues with ordering of HDA codec and controller
suspends in the runtime PM flows. The implemented logic for SOF is
similar to what has been used by the Intel AZX HDA driver.
To implement this, first a fix is needed to hdac_hdmic ASoC codec
driver. SOF framework also needs to be extended to allow SOF devices
to implement a runtime_idle callback. Third, concrete implementation
is in a separate patch for APL/CNL Intel hardware, for which strict
ordering of codec-controller power down sequence needs to be
maintained.
As this extends the SOF device interface, Pierre asked me to
send to the list for wider review. This series has been prereviewd
at SOF github as:
https://github.com/thesofproject/linux/pull/1003
v2 resend:
- no changes since v2 -- resending as 2 weeks has passed and
multiple reviewed-by acks already received
v2:
- Rebased on broonie/for-next, there was a conflict with patch
"ASoC: SOF: Intel: hda: release link DMA for paused streams during suspend"
- Added Reviewed-by tags from v1 round
