Subject: pinctrl: abx500: retire phandle config mechanism
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eea11b0baa63ed871e16ca4513db56341e4c3598;p=linux-beck.git

pinctrl: abx500: retire phandle config mechanism

The abx500 pin control driver supported a method of fetching the
generic config from a phandle to a separate node using the
"ste,config" as a phandle. This is not used in any device trees
and not documented in the bindings, so drop this support.
