The binding follows the way it is handled by the Mediatek binding to keep things consistent. This will initially be used by the RK3588 GPU power domain, which fails to be enabled when the GPU regulator is not enabled. It is not limited to that platform, since older generations have similar requirements. They worked around this by marking the regulators as always-on instead of describing the dependency.
