Further align HDA init sequence to the legacy non-DSP HDA driver by calling snd_hdac_set_codec_wakeup() during the chip init sequence.

2020-03-26ASoC: SOF: Intel: hda: do not leave clock gating off upon errorKai Vehmanen
The misc clock gating (MISCBDCGE) is disabled for controller reset and reenabled once reset is complete. Fix the case when error happens during reset, and clock gating is left disabled. The clock gating should be reenabled also in this case.

2019-12-10ASoC: SOF: Intel: add codec_mask module parameterKai Vehmanen
Add a module parameter 'codec_mask' to filter out unwanted HDA codecs from driver probe. E.g. on most systems, codec_mask=4 will limit to HDMI audio and exclude any external HDA codecs. Similar to 'probe_mask' module parameter of snd-hda-intel.

2019-10-01ASoC: SOF: Intel: hda: Disable DMI L1 entry during captureRanjani Sridharan
There is a known issue on some Intel platforms which causes pause/release to run into xrun's during capture usecases. The suggested workaround to address the issue is to disable the entry of lower power L1 state in the physical DMI link when there is a capture stream open.

2019-08-13ASoC: SOF: fix HDA direct MMIO accessPierre-Louis Bossart
The recent change to remove the bus->io_ops callbacks used an older version of the SOF code base, and when merged into Mark's for-next it invalidated changes, resulting in broken compilation identified by kbuild and reproduced during the weekly SOF rebase. Restore SOF code overridden by git merge and apply Takashi's intended change in the 'right' location.
