From b7a425e0d02b6c4a49732c3bbe13f09a619be01e Mon Sep 17 00:00:00 2001 From: Daisuke Nojiri Date: Tue, 13 Dec 2016 09:46:54 -0800 Subject: reef/electro: modify keyboard scan rate (from CL:415672) Slow the keyboard scan rate from 50 us to 80 us. This compensates the additional delay added to the KBO line by Silego / H1. BUG=chrome-os-partner:60335,chrome-os-partner:60615 BRANCH=reef TEST=check press key "f3" then system only output "f3" scan code.
