Subject: [PATCH] ARM: dts: socfpga: set the i2c frequency
Date: Tue, 9 May 2017 09:27:16 -0500 [thread overview]
Message-ID: <1494340036-26099-1-git-send-email-dinguyen@kernel.org> (raw)
Use 'clock-frequency' binding for the i2c node that will put the I2C driver
into the standard operating mode. 'speed-mode' was not a valid binding for
the I2C driver, remove it.
