Subject: [PATCH] ARM: dts: imx: Use 100 kHz I2C2 on Data Modul i.MX8M Mini eDM SBC
Date: Tue, 26 Apr 2022 00:16:04 +0200 [thread overview]
Message-ID: <20220425221604.262351-1-marex@denx.de> (raw)
The I2C2 has SMBus device SMSC USB2514Bi connected to it, the device is
capable of up to 100 kHz operation. Reduce the bus frequency to 100 kHz
to guarantee this I2C device can work correctly.
