Applicable to all you patches: a per-patch change log would be really
nice for reviewers. It can help them to focus on the parts that have
actually changed with respect to earlier revisions they might have
already reviewed.

Your branch needs a refresh, this file doesn't exist anymore.
You'll want to change sc7280-crd-r3.dts for the CRD <= 2.x and
sc7280-herobrine-crd.dts for the CRD >= 3.x

I agreed earlier that sorting by node name is correct, but that wasn't
entirely true. The nodes should be sorted by name within the 'device'
section, i.e. after the comment "/* BOARD-SPECIFIC TOP LEVEL NODES */".

Shouldn't this be:
pinctrl-names = "default", "sleep";
pinctrl-0 = <&wcd_reset_n>;
pinctrl-1 = <&wcd_reset_n_sleep>;
?
nit: make the ordering of properties (pinctrl, #sound-dai-cells) and
spacing within the node consistent for max98360a and wcd938x? Not
super-important, but since both are codecs and added by the same
patch, why not :)
