"nyan" goes here alphabetically (still ordered as "big").

In light of v1 and the above commit message referring to this as Google
Big, shouldn't this be "google,big", "nvidia,tegra124" and optionally
"google,nyan" as secondary string, independent of the new file name?

The Exynos5250 based Chromebooks use "google,snow" and "google,spring"
respectively, and I don't think there's any mention of Daisy at all in
upstream, unlike some ChromeOS sources.

Also, should we start documenting these google,* compatible strings to
please checkpatch.pl?

Any need to have the nodes this way? Shouldn't this rather be
dap-mclk1-pw4 as node name by conventions, with a dap_mclk1_pw4 label
for referencing if needed? Same below, obviously.

Add the label to the .dtsi where the node is first declared? Then you
can override it the safer &pwm { ... }; way. Same for all other nodes

indentation.
