ASoC: soc-pcm: indicate error message at dpcm_fe/be_dai_startup()
Indicating error message when failed case is very useful for debuging.
In many case, its style is like below.

	int function(...)
	{
		...
		return ret;
	}

	int caller(...)
	{
		...
		ret = function(...);
		if (ret < 0)
			dev_err(...)
		...
	}

This is not so bad, but in this style *each caller* needs to indicate
duplicate same error message, and some caller is forgetting to do it.
And caller can't indicate detail function() error information.

If function() indicates error message, we can get same and
detail information without forgot.

	int function(...)
	{
		...
		if (ret < 0)
			dev_err(...)

		return ret;
	}

	int caller(...)
	{
		...
		ret = function(...);
		...
	}

This patch follow above style at dpcm_fe/be_dai_startup().

ASoC: soc-pcm: indicate error message at dpcm_be_dai_trigger()
Indicating error message when failed case is very useful for debuging.
In many case, its style is like below.

	int function(...)
	{
		...
		return ret;
	}

	int caller(...)
	{
		...
		ret = function(...);
		if (ret < 0)
			dev_err(...)
		...
	}

This is not so bad, but in this style *each caller* needs to indicate
duplicate same error message, and some caller is forgetting to do it.
And caller can't indicate detail function() error information.

If function() indicates error message, we can get same and
detail information without forgot.

	int function(...)
	{
		...
		if (ret < 0)
			dev_err(...)

		return ret;
	}

	int caller(...)
	{
		...
		ret = function(...);
		...
	}

Now, dpcm_be_dai_trigger() user uses it like below.

	err = dpcm_be_dai_trigger(...);
	if (err < 0)
		dev_err(..., "ASoC: trigger FE failed %d\n", err);

But we can get more detail information if dpcm_be_dai_trigger() itself
had dev_err(). And above error message is confusable,
failed is *BE*, not *FE*.

This patch indicates error message at dpcm_be_dai_trigger().

Now, many place uses dpcm_path_get() like below

	ret = dpcm_path_get(...);
	if (ret < 0)
		goto error;
(A)	else if (ret == 0)
		dev_dbg(...)

But here, (A) part can be indicated at dpcm_path_get() not caller.
It is simple and readable code.

This patch do it.
Small detail behaviors will be exchanged by this patch.

	1) indicates debug info (= path numbers) if path > 0 case only
	   (It was *always* indicated).
	2) soc_dpcm_fe_runtime_update() is indicating error message
	   for paths < 0 case, but it is already done at dpcm_path_get().
	   Thus just remove it. but dev_dbg() vs dev_warn() is exchanged.

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.

Dmitry Osipenko (16):
  ASoC: tegra20: ac97: Add reset control
  ASoC: tegra20: i2s: Add reset control
  ASoC: tegra30: i2s: Restore hardware state on runtime PM resume

This patch adds jsl_rt5682_rt1015p which supports the RT5682 headset
codec and ALC1015Q-VB speaker amplifier combination on JasperLake
platform.

This driver also supports ALC1015Q-CG if running in auto-mode.
Following table shows the audio interface support of the two
amplifiers.

In practice the access to the pointer is protected by another

a test to avoid doing the memcpy if the pointer is NULL or the size is
zero.

ASoC: tegra30: i2s: Remove handing of disabled runtime PM
Runtime PM is always available on Tegra since commit 40b2bb1b13
("ARM: tegra: enforce PM requirement"), hence there is no need to
handle the case of a disabled RPM by Tegra drivers. Remove handing
of a disabled runtime PM from Tegra30 I2S driver.

ASoC: tegra30: i2s: Correct driver removal order
Tegra30 I2S driver has a wrong driver removal order, which should be
opposite to the registration order, but it's not. In particular the
runtime PM is disabled in a wrong order. Fix the order.

ASoC: tegra20: i2s: Add system level suspend-resume callbacks
Add system level suspend-resume callbacks in order to ensure that I2S
is gated before system is suspended. This puts Tegra20 I2S driver on
par with the Tegra30 I2S driver.
