From 80a53a8e5a2ee0074f6fe1b35311321ca2ecf372 Mon Sep 17 00:00:00 2001 From: Kapil Porwal Date: Fri, 8 Nov 2024 06:04:41 +0000 Subject: mb/google/var/riven: Optimize the stop delay for touchsreen Reduce stop delay for touchscreen based on the latest spec (EKTH6915 Product Spec_V1.0). This will optimize the touch response time to keep the S0ix resume time under 500ms. BUG=b:378012214 TEST=Verify improvement in resume time on Riven.
