The simple-mux driver requires gpiolib. Currently it selects GPIOLIB but
since the use of select can lead to issues with randconfig let's instead
depend on GPIOLIB, select is more idiomatically used for Kconfig symbols
that are not user selectable but GPIOLIB is user selectable.

This series extends the sun4i-i2s binding and driver to support some
newer versions of the hardware. Each instance of the hardwar now has
multiple input/output pins, and channels can be muxed between them.
Since so far the driver only supports a "default" linear channel map,
the driver changes are minimal.

The Madera CODECs use regmap_irq functions but nothing ensures that
regmap_irq is built into the kernel. Add dependencies on the ASoC
symbols for the relevant MFD component. There is no point in building
the ASoC driver if the MFD doesn't support it and the MFD part contains
the necessary dependencies to ensure everything is built into the
kernel.

When the DMIC_ENA bit is set the analogue inputs are disconnected from
the digital core of the chip, in favour of the digital microphones.
Currently the driver will always enable DMIC_ENA whilst the GPIOs are
configured for the DMIC function, this means the user can't currently
use both the analog inputs and the digital inputs in one system.
Add an additional DAPM mutex that allows switching between analog and
digital inputs into the digital core.

H6 expands the number of channels in each direction to 16, so the slot
number fields need to be expanded from 3 to 4 bits each.
R329/D1 expand that further by allowing each of the 16 slots to map to
any of 4 data pins. For TX, the configuration of each pin is
independent, so there is a copy of the mapping registers for each pin.
For RX, each of the 16 slots can map to only one pin, so the registers
were changed to add the pin selection inline with the channel mapping.

This series fixes DP/HDMI audio for RK3399 Gru systems.
First, there was a regression with the switch to SPDIF. Patch 1 can be
taken separately as a regression fix if desired. But it's not quite so
useful (at least on Chrome OS systems) without the second part.
Second, jack detection was never upstreamed, because the hdmi-codec
dependencies were still being worked out when this platform was first
supported.
base-commit: e783362eb5
When disabling a regulator fails while the device goes away, there is
little we can do and the machine is probably in enough trouble that any
action we'd want to take fails anyhow.
The return value used to be passed on in cs42l51_i2c_remove() (i.e. the
i2c device remove callback). But the i2c core ignores the error code
(apart from emitting a generic warning) and removes the device anyhow.
So return 0 unconditionally in cs42l51_i2c_remove(), and instead of
returning the error code to the upper layer emit a more helpful warning
message. After that nobody is interested any more in the actual error
code, so let cs42l51_remove() return void.

A copy of substream pointer is stored in priv structure during
rz_ssi_dai_trigger() callback ie in SNDRV_PCM_TRIGGER_START case

The driver used the locks only in rz_ssi_stream_is_valid() and assigned
the local substream pointer to NULL in rz_ssi_dai_trigger() callback but
never locked it while making a local copy.
This patch adds the rz_ssi_set_substream() helper function to set the

Add a new system-clock-fixed flag, which can be used to specify that the
driver cannot or should not allow the clock frequency of the mapped clock
to be modified. This behavior is also implied if the system-clock-frequency
parameter is set explicitly - the flag is meant for cases where a clock is
mapped to the DAI but which is, or should be treated as, fixed.
When mclk-fs is also specified, this causes a PCM constraint to be added
which enforces that only the corresponding valid sample rate can be used.
