From: Chris Packham Date: Wed, 23 Mar 2022 03:40:54 +0000 (+1300) Subject: dt-bindings: hwmon: Document adt7475 pin-function properties X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4fc1b113624784cf1a3b5b1ea813afca2a0b9dcc;p=linux.git dt-bindings: hwmon: Document adt7475 pin-function properties The adt7473, adt7475, adt7476 and adt7490 have pins that can be used for different functions. Add bindings so that it is possible to describe what pin functions are intended by the hardware design.
