Merge series "Fix reset controls and RPM of NVIDIA Tegra ASoC drivers" from Dmitry Osipenko <digetx@gmail.com>:
Hi,
This series adds missing hardware reset controls to I2S and AC97 drivers,
corrects runtime PM usage and drivers probe/remove order. Currently drivers
happen to work properly because reset is implicitly deasserted by tegra-clk
driver, but clk driver shouldn't touch the resets and we need to fix it
because this breaks other Tegra drivers. Previously we fixed the resets of
the AHUB and HDMI codec drivers, but turned out that we missed the I2C and
AC97 drivers.
Thanks to Paul Fertser for testing the pending clk patches and finding
that audio got broken on Tegra20 AC100 netbook because of the missing I2S
reset.
Changelog:
v5: - After taking another look at the drivers I noticed couple more
things that could be improved. These new patches correct runtime PM
and probe/remove order of the drivers:
ASoC: tegra20: spdif: Correct driver removal order
ASoC: tegra20: spdif: Remove handing of disabled runtime PM
ASoC: tegra20: i2s: Add system level suspend-resume callbacks
ASoC: tegra20: i2s: Correct driver removal order
ASoC: tegra20: i2s: Use devm_clk_get()
ASoC: tegra20: i2s: Remove handing of disabled runtime PM
ASoC: tegra30: i2s: Correct driver removal order
ASoC: tegra30: i2s: Use devm_clk_get()
ASoC: tegra30: i2s: Remove handing of disabled runtime PM
ASoC: tegra30: ahub: Reset global variable
ASoC: tegra30: ahub: Correct suspend-resume callbacks
ASoC: tegra30: ahub: Remove handing of disabled runtime PM
v4: - Added missing prototype for reset_control_bulk_put().
v3: - Fixed reset stubs for !CONFIG_RESET_CONTROLLER.
v2: - After some more testing I found that I2S control logic doesn't require
I2S clock to be enabled for resetting. Hence it's fine to have I2S to
be reset by parent AHUB driver, so I dropped "tegra30: i2s: Add reset
control" patch.
- While I was double-checking resets on Tegra30, I found that that
Tegra30 I2S driver has a broken runtime PM which doesn't restore
hardware state on resume and it's lost after AHUB RPM-resume.
Thus, added this new patch "tegra30: i2s: Restore hardware state
on runtime PM resume".
- Added new patches which switch AHUB driver to use reset-bulk API.
I took the RFC patch from Philipp Zabel, fixed it and added
devm_reset_control_bulk_optional_get_exclusive_released() that
will be useful for further Tegra GPU patches. This is a minor
improvement which makes code cleaner.

ASoC: Intel: bytcr_rt5640: Add used AIF to the components string
Depending on which AIF is used the UCM profile needs to setup
a different path through the rt5640's "Digital Mixer Path" graph.
ATM the UCM profiles solve this by just enabling paths to the outputs /
from the input from both AIF1 and AIF2 and then relying on the DAPM
framework to power-down the parts of the graph connected to the
unused AIF.
But in order to be able to use hardware-volumecontrol and to use
the hardware mute controls, which are necessary for mute LED control,
the UCM profiles need to know which AIF is actually being used.
Add a new "aif:1" or "aif:2" part to the component string to provide
info about the used AIF to userspace / to the UCM profiles.
Note the size of byt_rt5640_components is not increased because the
size of 32 chars already is big enough.
Rename 'Mono DAC Playback Volume' to 'DAC2 Playback Volume' and move it
from rt5640_specific_snd_controls[] to rt5640_snd_controls[].
The RT5640_DAC2_DIG_VOL register controlled by this mixer-element has
nothing to do with the Mono (Amplified) output which is only available
on the ALC5640 chip and not on the ALC5642 chip.
The RT5640_DAC2_DIG_VOL volume-control is the main volume control for
audio coming from the I2S2 / AIF2 input of the chip and as such is also
available on the ALC5642.
This commit results in the following userspace visible changes:
1. On devices with an ACL5640 codec, the 'Mono DAC Playback Volume'
control is renamed to 'DAC2 Playback Volume' allowing the alsa-lib
mixer code to properly group it with the 'DAC2 Playback Switch' which
is controlling the mute bits in the RT5640_DAC2_DIG_VOL register.
Note the removal of the 'Mono DAC Playback Volume' is not an issue for
userspace because the UCM profiles do not use it (the UCM profiles are
shared betweent the 5640 and 5642 and only the 5640 had this control).
2. On devices with an ACL5642 codec, there now will be a new
'DAC2 Playback Volume', grouped with the 'DAC2 Playback Switch'
Having a complete 'DAC2 Playback Volume' / 'DAC2 Playback Switch' pair
on both variants will allow enabling hardware-volume control by
setting the UCM PlaybackMasterElem to "DAC2" on devices where the
I2S2/AIF2 interface of the codec is used.
