+ROCKCHIP with MAX98357A/RT5514/DA7219 codecs
+Required properties:
+- compatible: "rockchip,rockchip-sound"
This is generic, but the binding seems to be very specific to only 3
specific codecs. Listing all 3 codecs seems a bit strange. Perhaps a
name related to the board name would be better.
Yes, I think that I should rename to rk3399_max98357a_rt5514_da7219.c, it is related to the rk3399 boards.

What's the size? always 3?
Not always 3, the size is limited by machine driver, The similar approach with mt8173-rt5650-rt5676.txt.
+- rockchip,codec: The phandle of the MAX98357A/RT5514/DA7219 codecs
Please make the size and ordering clear.
