From f6b957fdce50ddbd1899948ab109cca64e571eba Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 9 Apr 2015 10:59:27 -0500 Subject: ARM: dts: am437x-sk: reduce col-scan-delay-us The new AM437x SK Beta boards have removed the large capacitors on the gpio-matrix column lines which means we can reduce col-scan-delay-us to 5us without loosing functionality.
