I see that a master clock (mclk) is added in patch 6/6 but the
max98088 codec driver does handle this clock.
If the SoC XCLKOUT provides the master clock to the max98089
codec in Spring like is the case for the max9809{0,5} codecs
in the Snow and Peach Pit/Pi Chromebooks then you need to do
something along the lines of the following commits:
e3048c3d2be5 ASoC: max98095: Add master clock handling
b10ab7b838bd ASoC: max98090: Add master clock handling
If that's the case you also have to mention in the DT binding
doc that "clocks" and "clock-names" are optional properties
like Documentation/devicetree/bindings/sound/max9809{0,5}.txt.
Best regards,
Javier
