Subject: [PATCH AUTOSEL 5.8 19/20] i2c: mediatek: Send i2c master code at more than 1MHz
Date: Mon, 21 Sep 2020 10:40:26 -0400 [thread overview]
Message-ID: <20200921144027.2135390-19-sashal@kernel.org> (raw)
In-Reply-To: <20200921144027.2135390-1-sashal@kernel.org>
From: Qii Wang <qii.wang@mediatek.com>
[ Upstream commit b44658e755b5a733e9df04449facbc738df09170 ]
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.
