From a76e6542d1ab39ca50777f3fd0146151d0868c5c Mon Sep 17 00:00:00 2001 From: Tristan Shieh Date: Mon, 8 Apr 2019 11:01:40 +0800 Subject: mediatek: Use the 64-bit timer GPT4 is a 32-bit timer and the counter of GPT4 will overflow in about 330 seconds (0xffffffff / 13MHz). Timer and delay functions will not work properly if the counter overflows. To fix that we should use the 64-bit timer (GPT6).
