[PATCH 1/2] regulator: axp20x: Fill regulators_node and of_match descriptor fields

[Chen-Yu Tsai]

This patch fills the DT related fields in the regulator descriptors,
which can then be used by the regulator core's simplified DT code.

Signed-off-by: Chen-Yu Tsai <wens at csie.org>

This patch still has many lines over 80 characters. However I would like
to separate reformatting and functional changes. I can do another patch
over this one if line length is an issue.
