For SM-based SoCs (i.e. MX95, MX943), GPR configuration is performed by the SM coprocessor. Thus, GPR is transparent to the software and does not need to be described in the devicetree. Make it optional.

Medium quality sound (MQS) is used to generate medium quality audio
|
|
via a standard GPIO in the pinmux, allowing the user to connect
|
|
stereo speakers or headphones to a power amplifier without an
|
|
additional DAC chip.
