From e3be9c05d503739b14fb1b0a303a3ea4f8d5e032 Mon Sep 17 00:00:00 2001 From: Shelley Chen Date: Wed, 30 May 2018 20:15:18 -0700 Subject: mb/google/poppy/variants/nami: Add delay to enable_gpio during Elan power on During measurement of signals during Elan touchscreen power on, saw that the enable_gpio delay was not sufficient as there is a +1.5 ms delay during power on. Adding more delay to take this into account.
