From 35bd7afafe9d80728feae9f481ec169d785747e6 Mon Sep 17 00:00:00 2001 From: Ren Kuo Date: Mon, 14 Nov 2022 10:18:32 +0800 Subject: [PATCH] mb/google/brya/variants/volmar: Update ELAN touchscreen timing ELAN updated the datasheet, the HID/I2C protocol's T3 delay time is 150ms now. Modify the volmar's delay time to follow the requiremnet. BUG=b:257073343 TEST=Build firmware and measure the T3 timing of resume and boot up on volmar DUT. Run Suspend/Resume with UI test and got pass.
