Hi, i rebuild the Edison-image. and i don't have the <i2c_dw_sysnode> direction and <mode> file, i'm sure that
“Device Drivers -> I2C support -> I2C Hardware Bus support -> Synopsys DesignWare Controller” is selected .but i don't know CONFIG_I2C_DW_SPEED_MODE_DEBUG in where..would you mind giving me some advise?
