Software nodes allow us to represent hierarchies for device components
that don't have their struct device representation yet - for instance:
banks of GPIOs under a common GPIO expander. The core gpiolib core
however doesn't offer any way of passing this information from the
drivers.
This extends struct gpio_chip with a pointer to fwnode that can be set
by the driver and used to pass device properties for child nodes.
This is similar to how we handle device-tree sub-nodes with
CONFIG_OF_GPIO enabled.

Support new nvidia,fixed-parent-rate device-tree property which instructs
I2S that board wants parent clock rate to stay at a fixed rate. This allows
to play audio over S/PDIF and I2S simultaneously. The root of the problem
is that audio components on Tegra share the same audio PLL, and thus, only
a subset of rates can be supported if we want to play audio simultaneously.
Filter out audio rates that don't match parent clock rate if device-tree
has the nvidia,fixed-parent-rate property.

SPDIF and other SoC components share audio PLL on Tegra, thus only one
component may set the desired base clock rate. This creates problem for
HDMI audio because it uses SPDIF and audio may not work if SPDIF's clock
doesn't exactly match standard audio rate since some receivers may reject
audio in that case. Filter out audio rates which SPDIF output can't
support, assuming that other components won't change rate at runtime.

SND_SOC_SOF_DEVELOPER_SUPPORT contains options affecting how the built
SOF driver stack will behave, enables debug options and other features.
These options have no meaning if the SND_SOC_SOF is not even enabled.
If we have SOF client options under developer_support and debug they can
be selected to be built even without the core, but they do need symbols
from the core (the sof-client API) which can result build failure.
In Kconfig we can have
SND_SOC_SOF_TOPLEVEL=y
SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST=y
for example, which will make the flood client to be built, but the SOF core
is not as SND_SOC_SOF is not selected.
