From: Fabio Estevam Date: Fri, 8 Dec 2017 14:11:33 +0000 (-0200) Subject: dt-bindings: fec: Make the phy-reset-gpio polarity explicit X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=24fd3190817e96b2a57531986bfb6e951df3ee96;p=linux.git dt-bindings: fec: Make the phy-reset-gpio polarity explicit The GPIO polarity passed to phy-reset-gpio is ignored by the FEC driver and it is assumed to be active low. It can be active high only when the 'phy-reset-active-high' property is present. The current examples pass active high polarity and work fine, but in order to improve the documentation make it explicit what the real polarity is.
