From b44658e755b5a733e9df04449facbc738df09170 Mon Sep 17 00:00:00 2001 From: Qii Wang Date: Thu, 17 Sep 2020 19:55:42 +0800 Subject: [PATCH] i2c: mediatek: Send i2c master code at more than 1MHz The master code needs to being sent when the speed is more than I2C_MAX_FAST_MODE_PLUS_FREQ, not I2C_MAX_FAST_MODE_FREQ in the latest I2C-bus specification and user manual.
