Subject: [PATCH 4/4] arm64: rk3399: r4s: disabled i2c4 bus during the system boot process
Date: Tue,  6 Jul 2021 22:44:00 +0800	[thread overview]
Message-ID: <20210706144400.8665-4-peterwillcn@gmail.com> (raw)
In-Reply-To: <20210706144400.8665-1-peterwillcn@gmail.com>

Data transmission on the I2C4 bus is not required during the system boot process,
so it is disabled
