Subject: Input: gpio-keys - allow disabling individual buttons in DT
X-Git-Tag: v4.5-rc1~16^2^2
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=809d9516da73345cca587743b57e45e9095d851e;p=linux.git

Input: gpio-keys - allow disabling individual buttons in DT

Add support to disable buttons from DT via status property if given button
is not supported on given platforms. This will help re-using existing dtsi
files across multiple platforms.
