A workaround is to call hrtimer_cancel() in dummy_hrtimer_sync() which
is called certainly before other blocking ops.

The DSP can have more than one cores. In that case the secondary
core has to be managed by the driver. This patch adds the changes
to driver infrastructure to support multiple core.

A new object skl_dsp_cores is introduced to support multiple
core. Helpers skl_dsp_get_core() skl_dsp_put_core() help to
managed the cores.

Many of the power_up/down and DSP APIs take additional argument
of core_id. The primary core, 0 is always powered up first and
then on demand second core.

reg-8a assign the tracking source for each ASRC tracker. The default
value is 0x0000 which means all ASRC trackers will track LRCK1. But
in most case, we wish each ASRC tracker track the corresponding LRCK.
i.e. ASRC1 tracks LRCK1, ASRC2 tracks LRCK2 and so on. So, we rewrite
reg-8a as 0x0123.

3276d0aa0b ASoC: dwc: make pcm support built-in when necessary
The new PIO mode for the dwc audio driver causes a link failure
when it is built as a loadable module but the audio driver is built-in:

sound/built-in.o: In function `i2s_irq_handler':
:(.text+0x58c64): undefined reference to `dw_pcm_push_tx'
sound/built-in.o: In function `dw_i2s_probe':
:(.text+0x593dc): undefined reference to `dw_pcm_register'

We could link both into a single module, but apparently the
author intended them to be separate, so this instead changes
the Makefile to force the pcm module to be built-in if the
base module is. This is a bit hacky but not as bad as trying
to work around it in Kconfig language.

3915bf2946 ALSA: seq_timer: use monotonic times internally
The sequencer client manager reports timestamps in units of unsigned
32-bit seconds/nanoseconds, but that does not suffer from the y2038
overflow because it stores only the delta since the 'last_update'
time was recorded.

However, the use of the do_gettimeofday() function is problematic
and we have to replace it to avoid the overflow on on 32-bit
architectures.

This uses 'struct timespec64' to record 'last_update', and changes
the code to use monotonic timestamps that do not suffer from leap
seconds and settimeofday updates.

As a side-effect, the code can now use the timespec64_sub() helper
and become more readable and also avoid a multiplication to convert
from microseconds to nanoseconds.

We want to remove all time_t users from the kernel because of

'unsigned int', which seems more fitting anywhere.

  4) __pm_runtime_resume()

The rpm_resume() returns 1 when the device is already active.
Because the return value is unmodified, the hdac regmap read/write

The ak4613 driver is using a regmap cache sync to restore the

register cache which means that the resume is never going to work and we
trigger asserts in regmap.  Fix this by enabling caching.

5d76de61dd ASoC: adau17x1: Add support for specifying the MCLK using the CCF
The devices from the ADAU17X1 family all have a MCLK clock input which
supplies the master clock for the device. The master clock is used as the
input clock for the PLL. Currently the MCLK rate as well as the desired PLL
output frequency need to be supplied by calling snd_soc_dai_set_pll() form
a machine driver.

Add support for specifying the MCLK using the common clock framework. In
addition to that also automatically configure the PLL to a suitable rate
if the master clock was provided using the CCW. This allows to use the
CODEC driver without any special configuration requirements from the
machine driver.

While the PLL output frequency can be configured over a (more or less)
continuous range the narrowness of the range and the other constraints of
the clocking tree usually only result in two output frequencies that will
actually be chosen. One for 44.1kHz based rates and one for 48kHz based
rates, these are the rates that the automatic PLL configuration will use.
For the rare case where a non-standard setup is required a machine driver
can disable the auto-configuration and configure a custom frequency using
the existing mechanisms.

If the common clock framework is not enabled clk_get() will return NULL and
the driver will function as before and the clock rate needs to be
configured manually.

940adb280d ASoC: sgtl5000: Fix regulator support
Regulator support on SGTL5000 is broken because the VDDIO and
VDDA and VDDD should be powered on before enabling MCLK as
shown in Figure 4 of [1]. This requires moving control of the
regulators from the codec block to the I2C block of the driver.

The bulk of this patch consists of swapping the codec device with
the i2c client. The new field num_supplies in struct sgtl5000_priv
is used instead of ARRAY_SIZE(supplies) to handle the special case
when the internal LDO is used instead of external VDDD.

Note that ER1 in the SGTL5000 Errata document [2] suggests that
all designs should use external VDDD.

Since the internal LDO can only be enabled after I2C is available,
there's no benefit in treating it as a regulator, so this patch
removes the regulator structure surrounding it.

Instead, a single block of code in sgtl5000_i2c_probe() performs
the initialization sequence in section 2.2.1.1 of [3] and page
26 of [1].
