An errata exists for cs47l15 where the reset must be handled
differently and removed before DCVDD is applied. A soft reset is used
for situations where a reset is required to reset state. This does
however, make this part unsuitable for DCVDD supplies with a rise time
greater than 2mS.

Add the ability to get the clock for each clock input pin of the chip
and enable MCLK2 since that is expected to be a permanently enabled
32kHz clock.

GPL-2.0-only is the preferred way of expressing v2 of the GPL, so switch
to that. Remove some redundant copyright notices and correct some
instances where the wrong comment type has been used in header files.

This patch adds all the core support and defines for the Cirrus
Logic CS42L92, CS47L92 and CS47L93 smart audio CODECs.
Registers or fields are named MADERA_* if it is part of the
common hardware platform and does not conflict with any other
Madera codecs. It is named CS47L15_* if it is unique to CS47L15
and conflicts with definitions on other codecs.

Add variables to struct madera that will be shared by the
extcon and audio codec drivers to synchronize output state
during accessory detection. Also add a mutex to protect
the DAPM pointer.

Put the pointer to struct regmap_irq_chip_data into the parent
mfd structure so that the child irqchip driver does not need
a trivial private structure to store only this pointer. As
the irqchip child driver already has a pointer to the parent
struct madera it can use that to store the pointer. This also
means that the irqchip driver does not need a double-indirection
from its local struct to get at the parent struct madera.

This adds the generic core support for Cirrus Logic "Madera" class codecs.
These are complex audio codec SoCs with a variety of digital and analogue
I/O, onboard audio processing and DSPs, and other features.
These codecs are all based off a common set of hardware IP so can be
supported by a core of common code (with a few minor device-to-device
variations).
