The latest Exynos5433 Audio Subsystem bindings look like this
https://git.linuxtv.org/snawrocki/samsung.git/commit/?h=for-v4.9/mfd/exynos-lpass-v5&id=104cc6ad3ecc7c4c8ecf73663b93eb48b78f35aa
i.e. adma at 11420000, i2s0 at 11440000, serial at 11460000 should be subnodes of
the lpass at 11400000 node.
