Thanks for your comments, but I have a question about it.
When I remove the compatible name in the dts, there will be some error
message:
[    0.437562] mt6359-regulator: Failed to locate of_node [id: -1]
[    0.440612] mt6359-sound: Failed to locate of_node [id: -1]

Do you mean that we don't need any compatible name in dts, mfd and
regulator driver?
