From 24e62217060b56e75cea67d17d251180eb0ad447 Mon Sep 17 00:00:00 2001 From: Kevin Chiu Date: Mon, 29 Jun 2020 21:31:33 +0800 Subject: mb/google/zork: update G2 TS RST delay time in some m/b+BOE panel(G2 TS), G2 TS may still have chance to lost even rst delay time already meets spec definition: 10us (minimum). Restore G2 TS RST delay time to 50ms, we could have G2 TS working fine on those specific m/b+BOE(G2 TS) panel.
